Ben walks up and says that he knows it's stupid, but that he needs Felicity's help on the poetry final. Felicity says, "What, the Keats?" Ben replies, "Yeah. And please don't say 'the Keats' like it's the easiest stuff in the world." Felicity starts listing off poems, and Ben complains about the length of the poems. Felicity starts explaining it. Elena complains that she's trying to do her system. Ben says that Felicity owes him, since she pretty much caused him to fail that one paper, so now he needs to get at least a B on the final. Felicity looks guilt-stricken, and then agrees to do it.
