Hmm, since I am trying to find any variations of quests involving Yennefer and try to
explain her character with those scenes, I found several details, which I missed out the first or even second time, so that's nothing new, if you followed my other posts, but here are few from my memory, which probably most people missed in one way or another without knowing:
When you are at the wake with Yennefer at Skellige, you can optionally talk to several groups of people including 2 widows, who talk about their deceased husbands. After the talk Yennefer mentions that those skelligan women would make fine sorceresses with such attitudes, to which Geralt says that he doesn't know any skelligan sorceress, but Yennefer reminds him of Coral. A character in Sapkowski's latest book Season of Storms and a friend of Yennefer.
If you saved him, this will also occur in the quest:
Obviously this is a reference to Priscilla's song.
I think there was also something with that crazy guy in that ship. If you gave him all materials he needed, he will try to escape? Sorry, I don't know it exactly anymore, but there was something.
The quest about Freya's Garden has a lot of variations and different dialogues depending on what dialogue options you choose and whether you did the morkvarg quest before starting it or doing it during the quest. The quest itself won't change much, but in particular few dialogues with Yennefer change completely.
After this quest you can decide to follow Yennefer back to Larvik, while doing so, she will comment on that. Most people probably say at the end of the last quest to meet her later there, so that's also something easy to miss:
If you and Yennefer are asking an ex-prisoner how he escaped the prison, he will run off. Normally you will have no problems to catch him, but if you take your time and you are too slow, Yennefer will teleport and stop him with magic.
There are a lot more variations and really minor details, but I think these are details most people probably missed by accident. If you want every detail, well, there is
that thread
Sorry that it is just related to her, but I spent so much time on that, oh well...
It's more about being free to do whatever they want, but that's a discussion for being held
somewhere else.
