[quote=@Spoopy Scary]I think it would be interesting to see how their relationship would develop. They have very different upbringings, and they both have dealt with their hardships in different ways. While Fiona might chastise Finch's way of life, so they would butt heads often, but she might also have sympathy with him and bond over their mutual losses to the Dominion.[/quote]
I think you've summed it up pretty well. Fiona has some shaky morals when it comes to things like revenge, considering her own desire for it, but she very much looks down on thievery. That said, she'd rather try to change a person like Finch than punish him, since he's never wronged her personally. Especially if she sees that he would still like to be a good person. So... yeah! I imagine getting their backstories on the table for each other might not be easy, but they could probably bond over that, and clash in other ways.
