Quote from Marshall in Farhampton
Robin: Well, I'm glad that deleting our entire time together was so easy for you. But I guarantee you: Quinn is gonna find out eventually. Barney: No, she won't. I just need your help. Yours, too. I know you're out of it, but you have to promise not to tell Quinn, okay? Lily: Tell Quinn what? Barney: Exactly. Robin: No, she's really asking. Marshall: Tell Quinn what?
