Robin: Barney?
Barney: Hey, I've been looking for you. You okay?
Robin: Uh... yeah. I-I was just talking to the... the band about the... thing with the stuff. What are those?
Barney: My vows. I-I know it's bad luck to see the bride right before the ceremony, but I realized something. Marshall and Lily have broken most of their wedding vows, but they're still the best couple I know. I think their biggest problem was that Marshall didn't tell Lily the truth. So... I've decided to make only one vow to you, because it's the only one that really counts. Robin Scherbatsky, from this day forward, I am always gonna be honest with you. 'Cause I love you. I'll see you up there. Oh. Ted got that locket for you. He's the one you should thank.
Robin: Barney, wait. [they kiss]
