Sorry if this is a stupid question, but I have no clue how to continue Cassie's route. I have unlocked her safehouse, but I can't talk to her further. When I speak to her all she tells me is to, "Don't go telling anyone about this place, alright?" And I have no indication of where to go from my logbook.
I've been to the city and to Transylvania, is there something I'm missing that's obvious?
