Although Leonard doesn't realise it, Stephanie has moved in with him. Sheldon points this out because according to their roommate contract, various new rules go into effect, such as increasing the number of times for vacuuming. Leonard doesn't believe it until Penny walks him around his room and points out all the changes Stephanie has made, particularly the fact that she replaced his Bat Signal with a jewellery box.
Leonard begins to panic, especially when Stephanie starts buying him new clothes that he hates. Realising that the relationship is moving too fast for him, he runs to Penny for advice. However, whenever Leonard tries to follow Penny's advice to tell Stephanie how he feels, they instead end up having sex.

This episode starts on an evening. Probably the next day Leonard finds out that he and Stephanie are "living together". One of the following days he decides that he should ask her to move out. Since co-creator and executive producer Bill Prady stated in an interview that Leonard and Stephanie were together for three weeks in total, this episode also covers the events of one week ().

Leonard: (making it up as he goes along) Penny is one of our many neighbours. In our building, neighbours come and go, all the time, very casual, no dress code. In fact, some mornings I’ll just mosey down to the third floor in my pyjamas and have cereal with Mrs Vartabedian.
Sheldon: (Penny gives a wry half-grin, but Sheldon doesn't catch on) Really? I’ve never once been invited to have cereal with Mrs Vartabedian.
Leonard: She doesn’t like you. (to Stephanie) Don’t you have a gall bladder to remove? And I have to get into the shower and Penny has clothes to put on.
Stephanie leaves, with a pointed glance at Leonard. There is an awkward pause. Then ...
Sheldon: What could I possibly have done to offend Mrs Vartabedian?
Notes and Trivia
This episode ends with cliffhanger. When the next episode came along, fans wondered what happened with Stephanie, since she was obviously no longer living in Leonard's apartment and didn't even figure into his Christmas plans.
The scene where Penny stumbles into the boys' apartment in the morning without bothering to get dressed, looking for coffee, defines the relationship between the characters in a whole new and intriguing way. We have been watching this change happen over the first half of this season, as Penny becomes more and more part of the group. This is particularly clear in Panty Pinata Polarization, where she is so assimilated that Sheldon begins holding her to the same standards that he holds the others to.
