5x21 - Undressed

Zack/Clark/ Betsy Saga: Hayden dumps Zack. Clark presses Betsy too far for a relationship and gives her a gift. But Betsy says no, and leaves. While Zack is studying, Clark interrupts him and tells him ""do not enter the bathroom, you know what I mean."" Thinking that Betsy is in there, Zack takes a small peek to see what's happening. He sees Clark, jumping around, hitting things pretending that he is getting it on with Betsy. Zack opens the door more, and Clark is embarrassed. He then tells Zack that Betsy wasn't interested in him, and that he bought a gift for her (thanks to Zack's Hidden 1 Dollar Bills stash). He tells Zack, ""Go get her."" They then turn around to see Betsy witnessing the whole thing, saying ""I forgot my purse."" Zack and Betsy get together for their first time. [This saga ends]
