Currupting player character
So after trying his best to bring the party up against each other, Strahd actually managed to do so with one if my players. She was the last one surviving a TPK, and Strahd asked her to help him get to Ireena, in exchange he revived two of the dead party members.
So anyways, now she's on his side, and I'm kind of struggling with what I want to happen now. Strahd has asked the PC for a strand of hair of a new party member (one of my players didn't want their character revived and we wrote a new one) to be able to scry on all of them, and she did so without anyone else noticing.
She's torn between the two sides, her party and Strahd, and I'm unsure of how to handle this situation.
I don't want to actually hurt the other players by helping her betray them, but I also think Strahd would definitely use this to his advantage.
Any tips?
