I actually had a bit of a hard time, if you're still struggling. Ignore one of the PCs in the "cage room" with the strong wolfman
I might be misremembering the act but I think this is what was needed
What do you mean by "ignore one of the pcs", I tried not interacting with them but that didn't do anything. It still won't let me open any doors to get what I need to progress
One of the pcs says something along the lines of "dont let her out" and you need to ignore the warning
