Ted: I don't want her back. Or her front. I just want to move on. And this was an important step towards that. To moving on. [Ted and friends toast]
Future Ted: And you know, I really meant it. But still, that night, my mind began to wander.
[fantasy scene of Stella arriving at Ted's apartment:]
Stella: I made a terrible mistake.
Ted: I know. I'm a better person than you are.
Stella: You totally are. Let's get back together, and have way more sex than before.
Ted: Deal!
[reality: Ted hears a knock and goes to answer the front door:]
Tony: Hello, Ted.
