is it possible to have both quirks unlocked?
Care to elaborate?Some of them, yes.Like Jessica can have both Auntie and Adultress.But in the case of Chloe, she swaps between them if you ask her to.

You progress the main story, to a point where you go to hunt fey with Chloe.After the hunt she should have a new option if you talk to her in her room during the morning.
