Andrew Campbell : [secretary] Oh, first things first. We have to welcome a new member. Mona Vanderwaal will be joining us.
Spencer Hastings : Wait, what?
Andrew Campbell : Word came down from the faculty advisor this afternoon. Joining in school activities is part of her recovery.
[the other two girls share knowing looks]
Andrew Campbell : I guess she has a note from her doctor.
[Spencer looks down uncomfortably, and he realizes:]
Andrew Campbell : You guys have history. That's rough.
Spencer Hastings : [softly] Yeah, if you're downplaying it.
Spencer Hastings : There are forty-two clubs at Rosewood High. Mona could've picked any one of them. She's baiting me. And the only way to stop her, is to beat her fair and square.
