Thief discussion

I was confused as well. I think it was written that way in The Opportunist as a way of Olivia saying goodbye to Caleb. I don't think she would have gone through with the wedding or he would have stopped it otherwise. At least I'd like to think so!! :)

No, he didn't go. She just pictured him there as a way to say good bye and move on. I don't remember where but somewhere in Thief, he says that he didn't see olivia for a certain a mount of time and it included when she got married. I don't think he ever found out where she was getting married

I took it as she imagined Caleb at first and then see the real man she is about to marry.

Olivia was wishing it was him.
