Penny clearly loves Leonard and she has taken interest in what he likes, read/ watched Harry Potter, and has made Star Trek and Stars Wars references in past episodes. Yet she seems too uptight when taking the next step (moving in) with Leonard. Its about time Amy yelled at Sheldon, I wonder if he evolves (past his man child behaviour?)
You finally get to see a small (LARGE) glimpse of Mrs Wolowitz. She has some hilarious lines, and the kidnapping of Raj = priceless. As Howard said ''we'll see him at his Bar mitzvah'' lol
Overall a hilarious episode.
