Stella: Okay, I really overreacted last night. I'm sorry. Maybe I have some trust issues, but believe me, I have earned them. You said that I was looking for a reason for this whole thing to fall apart. Well, you're onto me, Ted. That's actually something that I do a lot. But I'm not going to do that with you. Ted, I'm in.
Ted: This is awkward. I have a girl here. [Stella playfully hits Ted]
Stella: Come on. There is something that I'm ready to do with you.
[later, at Stella's house:]
Stella: Ted, this is Lucy.
Ted: Hi, Lucy.
Stella: Lucy, this is Ted.
Future Ted: [v.o.] Stella and I thought our relationship was going to take a big step that weekend. Turned out, it took an even bigger one.
