In this episode, having spent an awkward night on the couch spooning Tamara, Alvin is relieved to discover in the morning that Johanna seems perfectly alright, but his good mood is soon spoiled once again... by Ms. Walsh, who, for some reason, decides that her reputation might be saved by moving the students from the classroom to the library. This does, however, offer Dennis a chance to extend his deal with Alvin after showing him some odd compromising webcam videos of Rachel, Lauren, and Ms. Walsh herself. Later in the evening, a heart-to-heart explanation with Johanna suddenly goes off in a strange direction after Alvin decides to plant a kiss on his sister's cheek...
