Ted: Okay, what's really going on with this locket?
Robin: [sighs] I'm gonna admit something that I couldn't admit until I found this. I've been having fears about marrying Barney. I mean, in many ways, he's-he's grown up into a mature, caring adult...
[meanwhile:]
Barney: I'm gonna shoot you with your own gun. [laughs manically]
[back:]
Robin: ...but I still don't know if he's ready for this. I still don't know if I am. But if I could find this locket. If it was still here, waiting for me. That would mean that the universe wanted me to marry Barney. And that everything was gonna be okay. And when it was gone, it was like, every doubt I-I ever had about Barney, about myself, got dug up. But I found it. [laughs] And everything's gonna be okay.
[Robin opens the box and finds it's empty]
