Marshall: [on the phone] Difficult stuff? What difficult stuff?
Lily: I don't know.
Marshall: Well, you did the right thing, baby.
Lily: Not entirely.
[flashback to Zoey in Lily's apartment:]
Lily: Zoey, wait! I don't hate you! We just can't be friends anymore because... Robin hates you.
[present:]
Marshall: [phone beeps] And that's Robin on the other line.
Lily: Oh, well, I'll let you take that. Love you, baby!
