Extended plot
The episode starts with Penny returning from The Cheesecake Factory and running into Leonard downstairs in the apartment building as he is checking his mail. They have a friendly conversation where Penny asks whether Leonard knows how to cook, to which he replies "not really". Penny asks what Leonard's plan is with Sheldon for the night. Leonard says they were going to watch Star Wars on. Penny mentions that he must have seen the a thousand times and Leonard replies that he has only watched it twice on Blu-Ray. Penny tells Leonard she was going to the movies tonight and asks if Leonard wants to go with her. A confused Leonard asks if it is okay for them to do that since they have not spent any time alone together since they broke up. Penny says it would not be a date but merely just a man and a woman hanging out and not having sex at the end of the night like a lot of Leonard's dates.

They reach Leonard's apartment and hear Sheldon yelling, "Oh Dear Lord, get away from me you !" Penny wonders what it is about and Leonard suggests Sheldon is smart and crazy enough to create a monster. When they get into the apartment, they found Sheldon freaking out over a (called a Blue Jay by Sheldon) perched on the window sill, trying to shoo it away. Penny is amazed that on top of all the things Sheldon fears, he is afraid of. Sheldon explains that it is called and that someday it will be recognized as a true disability and the  will be required to put a giant  over the building, adding that he has fear of nets too. Penny asks Leonard again if he wants to go to the movies with her and he immediately says yes. Penny leaves the apartment as Sheldon continues to try and shoo away the bird. Leonard tells Sheldon to ignore the bird so Sheldon pulls the to cover the window, noting that it is a good idea since attention is what birds want. The bird makes a sound and Sheldon starts freaking out again. Sheldon continues his attempts to shoo away the bird, this time by mimicking a cat's, but to no avail. Leonard comes out all dressed up to go out with Penny. He asks Sheldon what he thinks of his outfit, stressing that he does not want to give an impression to Penny that he thought it was going to be a date. He ends up going back inside his room to change as Sheldon decides to call but they just laugh at him. Sheldon draws a cat's face on a piece of paper and attempts the cat meow again, resulting in another failure. Meanwhile, after changing his outfit again, Leonard finally dressed up like how he used to dress up everyday to work.

At the, Penny wants to watch a  movie but Leonard wants to watch a on building a  on a river in . Penny insists on her choice and Leonard almost gives in until he tells her that he should pick this time since in the past they always followed Penny's choices. Penny did not realize that and thinks Leonard loved all those movies. Leonard confesses that he only went along with them since he was expecting sex at the end of the night and, since this was a non-date and sex was off the table, they should watch the documentary. Leonard even asks Penny to pay for her own ticket.

Back at the apartment, an impatient Howard and Raj are waiting for Sheldon to finish his work on his blast machine before starting the Star Wars movie. Howard says he will just start the movie since, if they wait any longer, may change the movie again. Sheldon asks Howard's assistance in finish setting up the machine and, while Howard works on it, Sheldon shares his ordeal with birds with Raj, which includes a calling him a "fat-ass". Howard finishes working on the machine, calling it Sheldon's "bird death ray". Sheldon tells him that it is not a and, if he did have one, he would be in his, enjoying the money the people of the Earth gave him for not using it. He starts the machine, but it does not scare the bird away, instead shattering the window. Raj comments with "that is one tough birdie".

Penny and Leonard are hanging out at after the movie. Leonard suggests that Penny enjoyed the movie since she when the village got flooded and the people had to relocate. Penny denies it, saying she only teared up because she was thinking how come the people could leave yet she could not. Leonard laughs and asks Penny if she would like some since he was getting some for himself. Penny says no and Leonard asks again by saying that she always says that but ends up eating half of his fries. Penny says that she only ate the "little crispy ones" that Leonard does not like, but he says he likes them and prefers to save them for the end but they are gone before he can eat them and he kept quiet about it. Penny interrupts, answering that he was expecting sex at the end of the night and Leonard agrees. He asks again if Penny would like some fries and she says yes. Leonard says "great" and asks her for money for her fries. While he goes to get their fries, Penny ends up with Kevin, a geeky  who is sitting behind their table. Penny even sits at Kevin's table, leaving Leonard alone.

Meanwhile, Sheldon tries to watch but the jay makes a noise again, causing him to get frustrated. Sheldon goes inside the closet and comes out with a while wearing. He carefully opens the window and tries to shoo the bird away using the broom. But the bird takes opportunity to fly into the apartment and lands on Sheldon's spot on the couch.

Back at the bar, Penny starts telling Kevin how wonderful the documentary she just saw with Leonard was by talking about and preserving the, while Leonard sits alone ing. Leonard finally stands up and asks to speak to Penny. He tells her that he knows she is going out of her way to talk to that guy because he said that their outing was not a date. Penny says she thinks the guy is cute and tells Leonard to talk to other girls if he wants to.

Back at the apartment, Sheldon enlists Amy and Bernadette's help with the bird. Amy asks Sheldon what he expects them to do and he says that, since they are both s, they should know how to deal with living things like the bird. Bernadette tells him that she specialized in microorganisms while Amy studied brains. Amy added that neither of them minored in bird-shooing. Bernadette asks Sheldon to come back into the apartment and has the bird perched on her arms. She suggests that the bird may be someone's. Sheldon tells Bernadette to slowly and carefully. Amy tells him that the only way to get over a fear is to interact with it, just like what he did with the. Sheldon approaches the bird slowly but backs away. Bernadette immediately yells, "Oh, just pat the bird, you big baby!", prompting Sheldon to stroke the bird. He still insists on flushing the bird down the toilet.

At the bar, Leonard finally finds someone to talk to, a woman named Laura. He lies to her about the stuff he enjoys such as, , and Jennifer Aniston movies. Penny comes over and apologizes for ditching him. He says he is fine with it and asks her to go away. Penny says Kevin left and asks to hang out. Leonard says that she only wants to hang out with him now that Kevin is gone. Penny asks Leonard what he has been telling Laura about her, but Leonard refuses and asks her to go hang out with other guys there. Penny asks Laura whether Leonard told her he owns two Star Trek uniforms and he wears them even when it is not. Leonard retaliates by saying Penny thinks s are only fought during. Penny responds with that half of Leonard's s are. Leonard replies by asking if Kevin knows that Penny's acting career involved a long-running role as in a local production of The Cheesecake Factory. Penny asks if Laura knows about Leonard's. Leonard asks Penny to spell "asthma". Penny can't and asks him to take her home. Leonard initially refuses but, noticing that Laura has left, agrees.

Meanwhile, Sheldon has overcome his fear of birds and is infatuated by the black throated magpie jay, holding and gazing at it longingly. He asks Bernadette to take a picture of him and the bird, suggesting he will use the picture on a, , and. Sheldon starts calling the bird his "little Lovey-Dovey". Bernadette tells him the bird still looks like someone's pet and they should make s. Sheldon agrees but says the posters should have the words "Is this your bird? Not anymore!", and starts planning the fun things he will do with the bird, including to all his enemies. Amy says Sheldon can borrow her cage if he wants since one of her test s slipped over a and broke its neck. Sheldon declines and says Lovey-Dovey will sleep in his own which he will retrieve from the window sill and put in his room. But the moment Sheldon opens the window, the blue jay flies out.

Penny and Leonard return to the apartment building and see Sheldon's poster of his missing jay on their way up the stairs, neither looking as if they had enjoyed the non-date. Leonard by saying that they went out, met some interesting people, and said horrible things about each other, so it was a magical night. Penny replies that she is not innocent but Leonard calls her stupid and she calls him an "asthmatic dumb-ass". Leonard admits he crossed a line and apologizes, even adding that his apology is sincere and is not expecting sex for it. Penny thanks him and apologizes too. Leonard thinks maybe they are not ready to go out as friends, but Penny says she likes the "take-charge and cocky" Leonard. Leonard immediately changes his mind and puts sex "back on the table" saying that he can be anything she wants him to be. Penny shakes her head and says good night. When Leonard enters his apartment, he tells Sheldon he had a weird night. Sheldon says he had a great night and takes off the orange blanket covering what turns out to be the jay's nest with an egg in it, revealing that the bird is female. He tells Leonard that he is going to be a.

Critics
"This season has featured a lot of Sheldon on his own. Or at least not interacting with many people. We have seen him playing dice, seeking revenge, obsessing over paintball or a  set. Those stories are fine and he remains one of the few characters on TV who can make scenes funny just through his performance... The Leonard and Penny story was pretty good too. Leonard standing up for himself and pointing out all the sacrifices he made when they were dating made for a fun story."
