This is good characterisation, but remember that she is
part of your Sanctum feature, so she should be available for your use. I like having to play out dealing with her fear of the place, so let's do that this time, but we should probably, eventually, resolve that for future convenience?
Maybe she had a scare? The curse did something to her? Maybe that was when she discovered the curse, or came to believe you about it? Or did
you only learn about the curse then? Or was that the first time it was serious enough to be a danger? Once she has learned enough to cope with it, or you get that danger under control, she may be confident enough to not need 'persuasion'
†? We can set a Clock (a general PbtA concept that is not mentioned in
Urban Shadows‡) and see how well you handle this situation, once the clock is filled, her (current) worry is mollified and you don't have to deal with it, but you may have to finish the clock over a few interactions.
This can also lead you towards understanding the 'curse'.

‡ If you don't know the concept we can talk about it. They are big part of games like The Sprawl, and Blades in the Dark, and Apocalypse World to a lesser degree (but they were there from the beginning).
