Sheldon offers a one a  trial period except "when she is cranky during her ". Leonard thanks him; however, he notes that he and Penny want to move in together... without Sheldon. He doesn't understand: how can they all move in together when he is not there! Leonard realizes that is scary for Sheldon. One is that he and Penny live in Apartment 4A and Sheldon could move in across the hall. Sheldon wonders if Leonard has taken, or if he has been hit in the head with a.

Later, Sheldon is at Amy's place complaining about all the changes: the university won't let him change his field of study, and Leonard doesn't want to live with him anymore. Amy made him some, which he says won't solve his problems, but does visibly calm him down. Amy points out that he is always complaining how lousy a Leonard is and maybe it would be good for him to live alone. Sheldon says that perhaps that is true. Amy then continues by saying that if it turns out that he doesn't like living alone, then maybe they could move in together. Sheldon that she would "love that", and "why don't we get engaged, buy a, start a family and spend our  years together!" Amy counters that it was just a thought. Sheldon demands that nothing change and everything stay the way it is. He also points out that Amy also made the Quik with the instead of the ; it s better this way, and he dislikes it.

She mentions that he flipped out over her suggestion that he move out so they could live together. He was so upset he couldn't understand her great idea that she and Sheldon move in together. Leonard says that he has had a couple of rough days and probably needs time to. Amy sits down and asks what they are doing; Penny says they are having a nice dinner together as a newly engaged couple, and Leonard adds that maybe Sheldon just needs some time alone - a lot of people need that. Finally Penny tells Amy to get out and she leaves.

Leonard nonetheless finds out that he is at the. He reasons that even though he loves s, it's late and they should go get him.

Critics

 * Jesse Schedeen for IGN- "Overall, this episode managed to live up to its name more than I might have expected. Things are finally changing on a sitcom where the status quo has always been pretty rigid and slow to evolve. It could be argued that the writers are guilty of returning to the same season-ending trope they so often rely upon. Once again, the season wraps up with a major character taking a dramatic trip and leaving the rest of the gang anxiously waiting his return. In this case, there's an element of unpredictability that should be fun. We have no idea where Sheldon will go or what he'll do on his cross-country travels. The potential is there for all sorts of new Sheldon-centric stories. Or he could just follow Leonard's example and come back quickly without really accomplishing anything."

Costume Notes

 * Sheldon wears his light blue TV test pattern t-shirt, his Quantum t-shirt from Thinker Collection , and his red 20-sided dice t-shirt.

Trivia

 * For the first time, Melissa Rauch and Mayim Bialik have appeared in every episode of a season.
 * Stuart's Comic Book Store suffers fire damage after he has an accident with a hot plate.
 * Sheldon takes to the rails after too many changes occur in his life. As a contrast, he is sensitive of hobos on the train in "The Locomotive Manipulation" (S7E15).
 * Stuart begins a new job as Mrs. Wolowitz's caregiver.
 * Mrs. Wolowitz's first name is revealed to be Debbie.
 * When complaining to Stuart, Sheldon tells him that his girlfriend loves him so much that she wants him to move in. That's the first time love has ever been mentioned in the Shamy relationship and even more incredible that Sheldon saw it and acknowledged it.
 * The second episode where someone attacks Leonard for damaging Shamy. First was "The Pulled Groin Extrapolation" - Sheldon karate chops Leonard in the back, giving him a message "She is not for you", clearly concerned about how well Amy and Leonard got on.
 * After saying that Sheldon could move across the hall, Sheldon asks him if he has been hit in the head with a coconut. That was the logical suggestion that little Spock gave to Sheldon for his situation in one of his dreams in "The Transporter Malfunction".
 * Despite his fondness for Amy, Sheldon had no farewell scene with her.
 * Penny out of character doesn't comfort Amy when she falls apart over Sheldon's departure.
 * This episode is the second where Sheldon tries to leave Pasadena forever. The first was "The Bozeman Reaction".

Quotes

 * Leonard: You can move across the hall.
 * Sheldon: Move across the hall? Did you take a marijuana?


 * Amy: (Hits Leonard with a pillow) How could you let him go?!


 * Sheldon: So, who’s watching her now?
 * Howard: A bowlful of M&M’s with a few Ambien tossed in.


 * Leonard: Okay. Now that everyone’s here, Penny and I have some big news.
 * Penny: We’re engaged!
 * Raj: Oh my goodness! And I thought me having sex with Emily would be the big news. [Hugging.]
 * Leonard: Hey, hey. What the hell?
 * Bernadette: You guys propose all the time. This never happens.
 * Penny: You’re right! [Hugging.]


 * Leonard: Hey buddy.
 * Sheldon: Hello.
 * Leonard: You okay?
 * Sheldon: I just got called into President Siebert’s office. The university won’t let me switch my field of study to inflation cosmology. They are forcing me to continue with string theory.
 * Howard: Why?
 * Sheldon: He said it’s why they hired me, it’s what my grant was designated for and that everybody has to do things they don’t want to do. He then gave an example of something he had to do even though he didn't want to do which was look at my stupid face.
 * Leonard: That was a rude thing to say…out loud.


 * Howard: Well, what if we use our vacation time?
 * Bernadette: I wanted go to Hawaii, not hell.


 * Beverly: Let me save you all of your hemming and hawing. Sheldon already told me that you and Penny are engaged.
 * Leonard: I hate that you talk to him more than you talk to me.
 * Beverly: Would you like for you and me to talk more?
 * Leonard: You know what? It’s probably fine.
 * Beverly: In any event, while I've had my misgivings about…Penny…Sheldon spoke very fondly of her, and if she is good enough for him, then she’d good enough for me.
 * Leonard: I’m your son. What about the fact that she’s good enough for me?
 * Beverly: Sure.
 * Leonard: Thanks, Mom.
 * Beverly: Leonard, would it make you feel better if your Mother approved of your life choices?
 * Leonard: Yes, it would.
 * Beverly: Yeah, well, you should work on that.


 * Penny: No Mom. It’s the same guy I've been going out with for the last two years. Yeah, the scientist. Well, it’s complicated. I mean, he works with lasers and atomic magnets. No, I did not see it coming. No, we did not set a date. No, I am not pregnant. Yeah, this is a first for our family. All right. Tell Dad I love him. I gotta go. Right. Bye.


 * Leonard: So listen. There was something I hoped to float past you. Now that Penny and I are engaged I thought we might want to talk about our living arrangements.
 * Sheldon: Of course. She has spent many nights here and you’re worried about preserving the myth of her virginity before the wedding.
 * Leonard: I’m not.
 * Sheldon: Good. Because not only has that ship sailed, but if it hit an iceberg countless men would perish.
 * Leonard: Actually this is about where she and I are going to live.
 * Sheldon: What do you mean?
 * Leonard: Well, well. We might want to live together.
 * Sheldon: Oh yeah, well. I have already given this some thought and I’m willing to let Penny live with us one day a week for a trial period. Now; obviously not when she is made cranky by the shedding of her uterine lining.
 * Leonard: That’s very sweet. But we were thinking more of us maybe living together…with not you.
 * Sheldon: I don’t understand. How can we all live together if I’m not there?
 * Leonard: Look I know this is…this is a change, and that sounds scary, but…
 * Sheldon: Where are you going to go?
 * Leonard: Well, I don’t know. We’re just starting to think about this. Maybe I’ll move in with Penny or maybe she and I’ll take this place and you can move across the hall.
 * Sheldon: Move across the hall? Did you take a marijuana?
 * Leonard: No, I did not.
 * Sheldon: Did you get hit on the head with a coconut?
 * Leonard: No.
 * Sheldon: Then I’m all out of guesses. What? Move across the hall.. Why would you even suggest such a thing?
 * Leonard: Because I love Penny and want to give her the life she deserves.
 * Sheldon: I see. You’re putting your future bride’s happiness above mine.
 * Leonard: Well, yeah.
 * Sheldon: Wow.


 * Amy: This might work out for the best. I mean, you’re always complaining what a terrible roommate he is. Like how he turns up the thermostat when you’re not there.
 * Sheldon: Ugh. It’s like walking into the Amazon. And no the good Amazon with one-day shipping. The awful one with bird and snakes.
 * Amy: You hate the sound of all those keys on this key chain.
 * Sheldon: Four keys! I mean, what does he think he is, a warden?
 * Amy: See, maybe you’ll love living alone.
 * Sheldon: I don’t know. Perhaps.
 * Amy: And if it turns out you don’t…you and I could live together.
 * Sheldon: You and…Oh sure. You would love that. And while we’re at it why don’t we get engaged, too. Why don’t get a little house and start a family? Enjoy our sunset years together. Do you hear yourself woman?
 * Amy: Sheldon, it was just a thought.
 * Sheldon: No, here’s a thought. You’re not moving in, Leonard’s not moving out. Everything stays exactly the way it is.


 * Leonard: So should we talk about setting a date?
 * Penny: Well, I’d like to pick one that works with my brother’s schedule.
 * Leonard: Okay. When would that be?
 * Penny: Uh, 12 to 18 months from now depending upon good behavior.


 * Stuart: I don’t mean to be rude, Sheldon, but my life’s kind of falling apart right now.
 * Sheldon: Your life? The university is making me do string theory. And my girlfriend loves me so much she wants to live with me. And now, the place I need to go when I’m sad smells funny.


 * Howard: Don’t take this the wrong way, but did you do this for the insurance money?
 * Stuart: No. Oh God, you sound like the police, the firemen, my parents, my therapist and the insurance company.


 * Leonard: Sheldon.
 * Sheldon: You tracked my phone?
 * Leonard: Yeah.
 * Sheldon: Boy, you chase one balloon for three miles.
 * Penny: We were worried about you.
 * Sheldon: Don’t be melodramatic. I’m just getting on a train and leaving forever.
 * Leonard: Seriously? You don’t even have change of clothes or a toothbrush.
 * Sheldon: My plan is to stop at malls and buy what I need. It’s called living off the land.
 * Leonard: Okay. I know you’re upset and they’re a lot of stuff going on, but it’s nothing we can’t workout. Come on, let’s get you home.
 * Sheldon: No, I've reached my breaking point. I need to leave. Now.
 * Penny: And go where?
 * Sheldon: It doesn't matter.
 * Leonard: So a few things don’t go your way and your best decision is to ride the rails like a hobo?
 * Sheldon: I suppose it is. Except I have a credit card. And I refuse to carry my laptop on the end of a stick. And I’d sooner die than eat beans out of a can.
 * Leonard: Come on, come home with us and tomorrow I’ll take you to Legoland.
 * Sheldon: Legoland is not the solution to everything. And it’s too much of a scene since that movie came out.
 * Leonard: Then what can I do?
 * Sheldon: Leonard, I am overwhelmed. Everything is changing and it’s simply too much. I need to get away and think.
 * Leonard: Oh, come on. You know you’re over reacting.
 * Penny: Leonard, hang on. Just come here. Maybe you need to let him go.
 * Leonard: What? Why?
 * Penny: It might be good for him.
 * Leonard: You know he can’t take trip like this himself.
 * Penny: He’s a grown man.
 * Leonard: No, he looks like a grown man. You've seen “Freaky Friday”. Sometimes little kids end up in big person bodies.
 * Penny: Leonard, we can’t protect him forever.
 * Leonard: I know, but…
 * Penny: He’ll be okay. You taught him well, Padawan.
 * Sheldon: Good Lord. Padawan’s the student, not the teacher.
 * Penny: Seriously, let him go.
 * Leonard: Sheldon, if you really need to do this I’m not gonna stand in your way.
 * Sheldon: I do.
 * Leonard: Okay. Good luck.
 * Penny: Be safe and call us.
 * Sheldon: I will.
 * Leonard: Bye, buddy. Sheldon.
 * Sheldon: Yes.
 * Leonard: I’m gonna miss you.
 * Sheldon: Of course you are.
 * Leonard: He just made that easier.


 * Amy: Okay Sheldon, thanks for checking in. Talk to you tomorrow? Okay, bye.
 * Leonard: He’s okay?
 * Amy: Actually sounds like he doing pretty well.
 * Penny: I really think this is going to be for the best.
 * Leonard: Me too. And he was able to take a sabbatical…
 * Amy: [Hitting Leonard with a pillow.] HOW COULD YOU LET HIM GO?
