Alright, battle's over - back to Novigrad. Save Triss for last of course.
Did the fountain scene a couple of times to see all the different dialogues. If you picked the Witcher option in the lighthouse, I think it's better to pick it again here. I like what she says. She isn't going to try to control him or tie him down. She's just going to make sure he has a home to come back to. I like to imagine that he is out on the path a bit more frequently and for a bit longer at first, maybe for the first 5 years or so. As he gets older, he begins to settle down some more. Less frequent trips, shorter duration, more time at home. The two of them live quite literally "happily ever after".
