Lily: You know, maybe it was good you called Karen.
Ted: It definitely was. And not just for me, but for her, too. Later that night, she sat down with Jerry, and she had the break-up talk she always avoided with me.
Future Ted: [v.o.] So you see, kids, sometimes when you have to have a tough conversation, the best thing to do...
Lily: Wait... a second. Wait a second. You said you were never gonna talk to Karen again, right?
Ted: Yeah.
Lily: Then how do you know she took your advice?
Ted: Hm? Oh, right. Well, about that... After she broke up with that dude, she called me, we went out, we hooked up, and we've been dating ever since. We're really seeing eye to eye this time. I don't know, it just feels different somehow. Here she comes now. Be cool!
