[@KatherinWinter] I understand her character. But you're telling me, you don't understand what I'm making her do. But it's not me, it's Bastian. Player knowledge, not character knowledge. Yes, I know and you know that maybe she wouldn't be able to do the hard task given to her and that it may not be the smartest decision and a rash move.

So what is Bastian? What is his thought process? That's the disconnect here. I perfectly understand why you're character is doing what they're doing. But you seem to be confusing, my actions and Bastian's actions. 

If the actions don't seem rationally and substantiated enough. Don't just go, well I, in real life, certainly wouldn't do such a thing. Ask a different question.

Is Bastian, someone who is impulsive and often unself critical, who sees more than what Elizabeth sees in herself. (or at least tells himself that, since you look like his previous wife.) Having one single lead, narrowed down to one location and one building. In the entire expanded world, so all you need to do is find a human to go there and find ONE person, even assume it's as she given the nickname. Cuts 50% of the people in the building, if not more. Because tell me how many women are in highly illegal gambling rings. And once finding that person, likely getting the most clues you've ever had to find the thing that Bastian considers his only true reason to carry on. Someone who you know/think changes their appearance on the spot, magic we've already establish can change and alter speech. So photo's and sketches or whatever, wouldn't be practical.

Does asking her to go in a building and find this person and trick her into going where Bastian can legally go, so he himself doesn't get in trouble. Not make sense, for his character?

If Elizabeth, not you, who doesn't understand Bastian. Then have her start asking questions..."Why do you trust me to do this? This may be your only chance to find the person that knows your kidnappers!? What if she leaves and I miss her? It will be my fault." "What should I ask? Will they even talk to a lowly slave?" I mean, seriously. There's many ways for this to go down in IC.
