The last thing Barry was expecting when he decided to accept the invitation to come here and help build a new society was that he would run into his ex girlfriend. The ex girlfriend that he still had very strong feelings for but had pushed away because he thought it was the noble thing to do.

Cisco said that the island was big enough that they wouldn't have to see each other, but the population was small enough that he didn't want things to be awkward between them.
The fact that she was so scantily dressed nearly made his eyes bug out of his head. Swallowing hard, he gave her a nervous smile. "Hey, Patty. You look great."
