And I so appreciate Hope. I always wanted to do the deal with Raphael to get the different end scene and I end up doing the HoH heist anyway, because it is entertaining and I want to free Hope. I love her little rants and the actress doesn't get enough credit imo.
I wish, there would be more interaction with Korilla about her sister, so we would know in advance and maybe, Korilla, while loyal to Raphael as she obviously is, would want to get her sister out of the picture. She seemed to genuinely cared for her little sister in the past, given her journals, you can find, so I would have loved that explored more.
Same with Wulbren if you find his diary. I always want to try sheeping Korilla and see if you can somehow get around ending her but then my "Healer dies first" instinct strikes along with Astarion's daggers. >_>
Korilla isn't a healer though, she is a warlock. Between Raphael and his cambions, she is actually the most harmless foe. I just always forget Yugir - I convince him, to fight with me ( bards, I never had to reload for that 30 persuasion check) and then the first thing he doesis killing Korilla. Next time I won't convince him and see, if I can save Korilla somehow. It's harder to keep Hope alive then, I guess,since she gets focused by Raphael normally and Yugir will probably go after her too. He seems to focus on the enemies with the lowest health pools.
