In "The Arrival", Michael and Vanessa are working on Michael's reading skills when his mother barges in and says he's supposed to be working on his reading, not spending time with girls. He claims that he is, but she doesn't buy it. When Vanessa defends him, his mother says that Vanessa doesn't know her son. The following rebuttal ensues:
Vanessa: I know him, all right. He's been a revolting, two-faced little creep, but he's not the only one to blame for that, is he?!
