This episode marks the return of Leslie Winkle (Sara Gilbert), now a regular character. We get to see more of her rivalry with Sheldon, and really, aside from their disagreement about what matter is made of, they're two of the most socially blunt people ever. Leonard and Penny are still circling each other, this time using other people to stir up jealousy, which is where Leslie comes in.
