Most of the character quest stories have been lackluster for me, but Victoria's was surprisingly awesome.

And, as a plus, it's also voiced by the game's best voice actress.

But I was expecting it to just be a yandere horror show and, while that's still present as always with Victoria, the CSQ actually tries to rationalize why she is the way she is, and shows the Knight Commander helping her become an ever-so-slightly healthier person.
