Recap

The gang are eating dinner at Leonard and Sheldon's apartment. When Howard tells Bernadette they should get going for the movie they want to see, Raj thinks he's being invited and gets up to go with them, much to Howard's annoyance. Penny has to go to work and Sheldon asks if anyone can drive him to the model train shop. Leonard and Amy are now left alone in the apartment, despite Leonard's discomfort at Amy sticking around. When Amy asks whether she is overstaying her welcome, Leonard is too polite to tell her to go.

As Raj drives Howard and Bernadette to the movies and Sheldon to the model train store, Howard suggests that he and Bernadette will one day move into his mother's house. Bernadette wonders if Mrs. Wolowitz is moving out, but Howard clarifies that they will be living with her. Bernadette is shocked to find Howard thinks she's going to move in with him and his mother. Back at the apartment, Leonard has just finished taking a shower and Amy is still there, reading his year book. Sheldon arrives home from the model train store, disappointed that the H-O/O gauge debate turned out to be nothing more than a front to sell H-O starter kits, which Sheldon duly bought. As Amy is leaving after her enjoyable evening with Leonard, she mentions she needs somebody to accompany her to a wedding. Leonard wonders why she wouldn't rather take Sheldon, but she says he behaved like a child at the last wedding they went to.

Bernadette goes over to the Wolowitz house to apologize to Howard. Howard says he shouldn't have sprung living with his mother on Bernadtte, and suggests they have a trial run this weekend. Elsewhere, Sheldon is playing with his model train set in the apartment. Penny asks Amy if she knows why a brilliant man likes playing with toy trains, but Amy would need to cut his brain open to figure that out. Leonard is all dressed ready for the wedding. At Mrs. Wolowitz's, Bernadette is surprised to learn she still cuts Howard's meat for him, but Howard promises Bernadette will get to do that for him one day.

At the wedding, Amy is disappointed with Leonard's lack of conversation and unwillingness to dance. Leonard explains he's not in a party mood with his kinda-sorta girlfriend 9,000 miles away. Amy convinces Leonard to lighten up and dance with her. In Howard's bedroom, he's playing with his lightsaber getting ready for bed, but Bernadette needs the bathroom which Mrs. Wolowitz is using.

In the apartment building stairwell, Amy is helping Leonard up the stairs after Leonard suffered an injury during the Hokey Pokey. Leonard thanks Amy for an enjoyable evening and reminding him that it's okay to have fun once in a while. After Leonard returns to his apartment, Amy goes over to Penny to talk about the evening, including how she accidentally made Leonard fall in love with her. In Sheldon and Leonard's apartment, Leonard recounts to Sheldon how he had a fun evening with Amy. When Sheldon gets the wrong idea, he karate chops Leonard to send a message: "She is not for you."

The next morning at Mrs. Wolowitz's house, Bernadette wakes Howard up after she and Mrs. Wolowitz make him breakfast. Bernadette says they're very different people and communication is hard for them, though they are starting to sound remarkably similar.
