2 or 3. Anna is waifu material. 2 because it can get her a new body and make it acceptable for readers who prefer virgin spouses. I would say do something similar to the other chick who had a huge crush on Blake but got assaulted as well. Blake has deflowered enough women to be more open to others imo.
I know I said 1, but thinking on it, that wouldn't fit her character arch as when she was found, she was one of the girls being raped and the darkini are very sexual so it would be a question of if she is completely over that trauma. likewise there are more options available such as werewolf etc in which you can add to the story
