Extended plot
Sheldon sneaks into Leonard's room early in the morning, all dressed up for an emergency. He sets off a siren on his phone, waking Leonard up for the. Leonard is not at all in the mood for Sheldon's antics, and wants to go back to sleep. Sheldon persists on, saying he tried to make the drill fun that night. Leonard chooses a "catastrophe card", turning out to be a 8.2 that hits Pasadena, which Sheldon sees as an "excellent choice". Leonard groggily puts on his and, afterwards, Sheldon pushes him into the wall, saying there's a hypothetical.

In the Cal Tech cafeteria, Howard shows Raj and Leonard the NASA for the space expedition. Raj reads off the list of astronauts, and Howard's name is at the end. Raj suggests that Howard should get himself a cool nickname, as all the other astronauts have one. Howard points out to Raj that the other astronauts have to pick it for him. Raj says that if he had to have a nickname, it should be " ". The guys notice that Leonard puts in six sugars into his coffee, and Howard figures out they must have had an emergency drill night. Sheldon enters the room, remarking on how bad Leonard did on the test, saying that if it were a real situation, he would be dead.

Leonard can't deal with Sheldon's incessant whining, and says that he's going home, asking one of the other guys to drive Sheldon back home later. Sheldon interjects, saying that he needs someone to take him to the, and as per the rules of the Roommate Agreement, he has to comply. Being fed up being told what to do, Leonard says that he is sick of the Roommate Agreement, as he is a roommate and not a. Sheldon asks whether or not he wants to activate Clause 209, which will nullify their friendship. Leonard immediately signs so that he can head home to sleep. At apartment 4A, Howard announces that he has some interesting news: the following week, he will be going to NASA orientation and zero-gravity elimination drills (as Bernadette calls it, "he's gonna learn how to in space"). Sheldon enters, greeting everyone as his "friend", except for Leonard, who he addresses as "Dr. Hofstadter". They both exchange their greeting, which is a and  Sheldon apologizes for being late, and goes to sit next to Amy, saying that she will be the one to take him to the dentist the next day. Amy explains that she can't, as they're in the middle of an experiment in her lab. Sheldon struggles to find someone to take him to various places, and in the end, no one wants to give him a lift to his destination.

Desperate for a friend and transport, Sheldon heads to Stuart at the comic book store. As a before dropping the big question on him, he asks Stuart out about his family, who confirms that his mom and dad are alive, but his grandparents are not. Sheldon gives his condolences, and then moves on to a "cheerier note", telling Stuart about the teeth cleaning, and asks for a lift. Stuart declines, saying that he can't and that he really doesn't want to. In a hurt attitude, Sheldon leaves the store.

Back at the guys' apartment, Raj continues to try and get Howard to think of a nickname for himself. Howard declines most of Raj's suggestions, like "Buzz" and "Crash", and they finally find a suitable name: "Rocket Man". Leonard comments that it sounds pretty cool, but Howard persists that he can't choose his own nickname. They devise a plan to suggest the name to the astronauts. Howard has a chat scheduled with astronaut Mike Massimino the following day, and during the chat, Raj will call Howard, who will set his  to ", to plant the seed. Sheldon enters, and out of courtesy, Leonard asks him if he went to the dentist. Sheldon replies 'no', but says he found someone who can come over to his house to do it for him. Leonard stands up from his chair, addressing Sheldon that he would be happy to take him to different places, but he wants to do it as a friend, not because some agreement said so. Sheldon says that is not possible, and it would only work if the full Roommate Agreement is restored. He then exits the room, saying he has to call his dentist.

Still in the apartment, Leonard is watching television, when the. Penny enters their apartment to see if their power also went out, worrying that it might just be her apartment. Sheldon enters, implementing the power outage drill, fetching some equipment from the cupboard. Penny suggests that Leonard come to her apartment because she has s, as Sheldon does not want to share his with Leonard. Sheldon comments that that is a fire hazard, and that s are more appropriate. Leonard fetches his Star Wars, mocking Sheldon with it. Leonard chooses to go to Penny's apartment, and Sheldon tries one last time to persuade/bug him to reinstate the Roommate Agreement. Penny easily convinces him otherwise, and they leave.

In Penny's apartment, Leonard and Penny share wine and pop over the lightsaber's light and candles that Penny had lit. Penny suggests they, and Leonard quickly agrees, though remarks that he thought they were going slow. As they start, Sheldon bursts informing them that he'll be making, and that they should not be alerted if they smell marshmallows burning. Sheldon says that Leonard can join him, but only if he reinstates the Roommate Agreement. Leonard once again declines, and Sheldon leaves. Penny feels bad that Sheldon looks so sad, commenting that Sheldon misses his buddy, and suggests that Leonard go talk to him.

Over a Bunsen burner, Sheldon is cooking himself some s'mores. Leonard enters the room, commenting that he thought Sheldon believed that candles were dangerous. Sheldon disagrees, saying that it's a Bunsen burner, and he knows how to use it; subsequently, the marshmallow he's toasting is set on fire, and he's forced to put it out. Leonard goes on to say that he would be happy to help Sheldon, but at least wants some recognition and a "thank you". Sheldon counter-offers, saying that there could be a "Leonard's Day", where they celebrate him. The agreement is restored. Penny enters, and explains how the power went out: Someone went down to the basement and pulled the main switch. All eyes are on Sheldon since they know who probably did it.

At the Wolowitz house, Howard and Raj test out to make sure his ringtone is set to "Rocket Man". Mrs. Wolowitz yells and asks when Howard will eat his breakfast. Howard yells back, saying he doesn't have time for that, and that he has a with NASA. The sound of a Skype call incoming is heard, and Howard answers. Mike Massimino appears on the screen, and they greet. Mike says the guys on the base calls him "Mass", which Howard confuses for a scientific equation, when it turns out to be the shortened version of his last name. Howard's phone goes off, and plays his ringtone. Mike recognizes the tune, and asks out about it. Howard says that it's his favorite song. A second after this, Mrs. Wolowitz yells to Howard that his are getting soggy. Howard apologizes, and Mike then dubs him "Froot Loops".

Critics
"If the writers really think Sheldon is better as a character by being that's fine. It really is. But if that's the case then he can't be the object of sympathy. And reflexively Leonard needs a backbone. Leonard continues to look like a wimp and a fool for constantly giving in to Sheldon's demands. If there really is no gratitude coming to him then he shouldn't settle for "Leonard's Day." If Sheldon isn't going to change then Leonard must or we are left to see him as a fool."

But in "The Countdown Reflection", the astronauts that go into space are Mike Massimino, Howard, and Dimitri Rezinov.
 * Howard's astronaut nickname is "Froot Loops". "Fruit loop"/"frootloop" is a for "a crazy or stupid person" and a pun on the breakfast cereal, which is the  Massimino was going for, as an obnoxious exchange with Howard's mom about the cereal occurs while Massimino is on Skype with Howard. As dramatic irony, the  additionally refers to a "fruit" (slang for a  person), in regards to his and Raj's odd and often commented-on relationship.

Mistakes

 * In "The Russian Rocket Reaction", Sheldon revealed that he started his list of mortal enemies in the year 1989, when he was 9 years old. This means that he was born in 1980, between April and May according to "The Peanut Reaction", which would mean that in February 2012, he would be 31 years old. However, in this episode, Leonard described Sheldon as a "30-year-old man who can't survive on his own". Yet, this can be overlooked, as it appears that Leonard was just being imprecise.
 * Sheldon tries to persuade Leonard to stay with him during the power cut with "all 61 episodes of the BBC series , even though the DVD pack he is holding only contains the original 52 episodes. Of the other nine episodes, three are from a 2009 special that is not featured in the collection, and the other six are due to be broadcast later on in 2012.
