Plot

Dividing up their possessions becomes an all-out war between Leonard and Sheldon. Stuart asks to live with Howard and Bernadette and tries to supplant Raj's efforts to help with the new baby.

Amy tells Sheldon they need to remove some of Penny's things and bring some of his from the old apartment. Sheldon goes there and takes practically everything with no regard for Leonard. He tells Leonard to pick something he wants and what he picks is something Sheldon holds dear. So in retaliation he does things like change the wifi password and rent out his room to a homeless guy. Stuart tells Howard and Bernadette that he was evicted and would like to stay with them. Bernadette reluctantly lets him. Raj is upset that Stuart is doing the things he normally does.—rcs0411@yahoo.com

Amy's suggestion to Sheldon that they redecorate their apartment - what was Penny's old apartment with all her possessions still there - leads to Sheldon wanting to move everything that was in his old apartment - where Penny and Leonard live - into his new apartment. Before he can do so, he and Leonard have to divvy up all those possessions. What starts out as a negotiation on each individual item between Sheldon and Leonard ends up being Sheldon wanting to keep everything, an attitude Leonard sees as Sheldon being selfish. An action by Leonard in obvious retaliation results in a battle of oneupmanship between the former roommates. Meanwhile, Howard and Bernadette decide to abide Stuart's request to move in - if only on a temporary trial basis - as Stuart has been evicted from his apartment. Howard and Bernadette's agreement is based on how well Stuart treated Debbie when they lived together, with the belief that Stuart may be able to provide some support when the baby arrives. Stuart moving in does not sit well with Raj as Raj and Stuart battle for the place as Howard and Bernadette's alpha third wheel, which Raj sees as more important now with the imminent arrival of the baby.—Huggo

In Sheldon and Amy's apartment, Amy wants to start redecorating their new home. Sheldon suggests that they move everything from Apartment 4A into their place. Amy figures they should ask Penny what she wants of her stuff including the big ugly painting Amy had made of the two of them to commemorate their friendship. Walking it over to 4A Penny has the same sick look on her face as in the painting.

In the Wolowitz's kitchen Stuart is offering Howard and Bernadette a book of coupons he made to help them do some tasks for the upcoming baby to have breaks like sweeping or a foot massage. Bernadette sees that one coupon is written on the back of an eviction notice. Stuart has nowhere to live and would appreciate that they let him stay a few weeks which bothers Bernadette, but is surprisingly fine with Howard, especially considering Stuart's extra pair of hands will really help them with their baby (like how he successfully nursed his mom back to health).

In Leonard and Penny's apartment Leonard, Sheldon and Amy want to help them hang it immediately. Penny offers it to Amy since it is also a picture of her. Amy may really like the painting, but Amy insists that Penny also likes it so much that Penny doesn't deny it. Sheldon figures that there are lots of things in Apartment 4A that he and Leonard should go through. The sword that Leonard and Sheldon jointly bought mounted by the front door should be Sheldon's since they have the painting or the avocado plant growing in the kitchen. Leonard sarcastically thinks that it is great that they are trading a collectible worth hundreds of dollars for a seed they rescued from the garbage.

Cleaning out the closet, Sheldon finds the Mr. Spock cuckoo clock they got at Comic Con. Leonard lets Sheldon have it which thrills Penny, but doesn't thrill Amy. Then Sheldon gets out their 3-D chess set and suggests that Leonard won't want it since he never won a game. Then Leonard tells him to take everything because Sheldon will have some reason that he should have every item. Amy thinks that Sheldon is being a little selfish. Leonard then says that there is one thing he wants - the official apartment 4A flag.

Stuart is helping set the dining room table after having cooked dinner. Bernadette is impressed as Stuart runs off to answer the doorbell. At the door, Raj is surprised that Stuart is living there, again. He claims to be there helping out since he needed a place to stay. Raj brought Chinese food which Stuart thinks will cause Bernadette's ankles to swell.

Leonard is on his computer and Penny is on her computer pad and neither of them can get onto their Wi-Fi. Sheldon had changed their password to "Ha-ha-ha; now I've got you." Leonard asks Penny what her next move for revenge would be and it was to sleep with the guy's best friend. She feels that she is already doing that. Leonard marches over to 4B and tells Sheldon to fix the password. He exclaims that two can play that game too. "All right, I tried," replied Leonard. Sheldon insists that that should be the name of his autobiography.

At dinner Raj and Stuart are trying to top each other. Raj suggests an infant CPR class and Stuart knows somebody who will come to the house. He also tells Bernadette to relax because he'll keep everything under control. Raj feels that everything was already under control.

In the laundry room Sheldon enters and finds Leonard is separating his shorts while wearing the apartment flag. Sheldon complains about the level he is stooping to. Leonard then shows the level he is stooping to by removing his underwear and rubbing his private parts on the flag.

Raj shows up at the Wolowitz's front door to assemble the cradle; however, Stuart already did it. Raj bought the cradle. Stuart says that he read about it on WhoGivesACrap.com. He loves them and wants to keep helping so he can continue to mooch off of them. Raj points out that he is the only emotionally needy person around here. Stuart invites him in to help with the baby swing.

Coming up the stairs, Penny says that she is thinking of going for a run. Leonard declines because the last time an old lady thought he was stalking Penny. Inside they find an old gentleman named Theodore (Christopher Lloyd) who rented Sheldon's old bedroom. Sheldon comes out and confirms that they have a roommate since his rent is paid up to the end of the month. Sheldon shoots back that Theodore has no ID whatsoever, though he does have a receipt from the blood bank.

Working on the baby swing, Raj and Stuart show Bernadette the two mobiles that could be installed. One is giraffes and the other is zebras. Bernadette chooses Stuart's zebra mobile. Bernie asks Howard to go to the market. Howard wants one of the help to do it. Bernadette insists that Howard go to the store; however, he still gets Raj to drive him. Stuart is going to paint Bernie's toenails.

Theodore is snacking, watching TV and sitting in Sheldon's spot as Leonard and Penny stare at him. They wonder if they should go to a hotel or stay and watch him. Theodore tells them that thanks to the coins he found in the couch, he can stay an extra day. Leonard goes to see Sheldon. Leonard calls Sheldon selfish, while Sheldon feels that he is being awful. Theodore provides an unwanted analysis that all of their anger is coming from love. Each is moving onto another phase of their lives and that it is easier to fight than face their feelings for each other. Amy agrees with whoever that old guy is. Sheldon has found leaving Leonard to be difficult, but he does want to stop fighting. Leonard can keep the flag and that is not just because it touched his private parts. Sheldon is even willing to do the same as Theodore.

Later, Leonard is adjusting the painting onto the wall next to his desk where the audience can't see it. Leonard thinks that eventually they won't even notice it. Penny denies that since it even shows up in her dreams. Theodore thinks that it brings the whole room together.

Finally Howard is lying on the couch of his living room playing on his phone asking who wants to paint the nursery. Both volunteer. Bernadette calls out saying that she thinks that she is in labor. Howard can't remember what the plan is, so Raj and Stuart take care of it. Stuart comes running into the living room with Bernie's suitcase. They all head out to the car.
