I think it's a very difficult power to role play, as I've already said to TillForPie privately. It's a subtle enough change that trying to run with it is like sewing with a rapier. One thing the GM said to me in PMs was that it's not very likely that Agnasci would contradict Gloria's suggestion that she can take care of herself and didn't need a place to stay. Agnasci did indeed contradict her just the same, but in my opinion the argument he was making was never about trusting her or having a high opinion of her. For Agnasci, he was arguing from a position of greed, not distrust. So on its face, it looks like I'm just ignoring Gloria's power.
Anyway, all in all I think the scene still went pretty well. This was the first and only moment of awkwardness I've felt this whole game, and we're one of the most content-filled games on the front page. It wasn't even really "awkward" come to think of it, just the players having a slightly different angle than the GM intended. I think part of the issue was that we took this minor power a vampire was using (who may or may not have any ill intent at all toward us) as something much more significant (or urgent, maybe? I don't know what the right word is) than it actually was.
