Quote from Robin in Unfinished
Robin: Okay, I left Don another message. [flashback to Robin on the phone:] Robin: "This just in is what I'm gonna say when I'm stabbing you." [present:] Lily: But that's impossible. You deleted his number. Robin: I tried to. But then this thing popped up on my phone that said, "Are you sure?" And I wasn't sure. I can't lie to my phone.
