I am in the middle of the Brother's in arm quest, and tried to recruit Triss. Talking with her, she said she has to finish something first. Now the quest marker is on Triss and the quest description is that I should help her finish what she has to do. Yet I cannot seem to progress a new quest line. I can ask her about her hand, though this is related to a previous quest in the Witch hunter's lair.
Is this quest bugged? Or do I have to get the relevant quest some other way?
