Quote from Robin in Sandcastles in the Sand
Robin: I got a second chance. Lily: What happened? Robin: He came by my place tonight... [flashback to Robin's apartment:] Robin: Simon. What are you doing here? Simon: I just feel like there's some unfinished business between you and me. Seeing you now... has made me realize that breaking up with you is the biggest mistake I made in my entire life. [back:] Lily: Oh, I like where this is going. [flashback:] Simon: I know this is crazy, and I'm only in town for a couple of days, but do you want to go on a date? [back:] Lily: He asked you out?! Oh, step into my web, Simon. Ted: The coup de grace. Barney: Finish him! [flashback:] Robin: I'd love to!
