If you side with the dawnguard you can convince Serana to cure her vampirism after you kill her father and finish the main questline. This is dependent on the conversations you have with her during the questline. A conversation option "Have you always been a Vampire?" will become available after Serana brings the scroll to Fort Dawnguard and you ask her to follow you. There are a few possible choices you can make while conversing with her about this however, if you ask her if she has ever thought about getting cured she will refer to her condition as a gift and state that she will never seek a cure for it. Should she say this you can still ask her to seek a cure after her father has been defeated but she will refuse and then refuse to speak to you about it further should you ask again. If you do wish for her to cure her Vampirism after the main questline then choose the option "Are you all right?" instead of asking her about a cure. Once you ask this she will end the conversation but you will still be able to convince her to seek a cure at Fort Dawnguard after her father is dead.
机翻:
如果你站在黎明守卫一边,你可以在杀死瑟拉娜的父亲并完成主线任务后说服她治愈她的吸血鬼。这取决于你在任务线中与她的对话。对话选项“你一直都是吸血鬼吗?”塞拉娜将卷轴带到黎明守卫堡并且你要求她跟随你后,就会出现。在与她谈论这个问题时,您可以做出一些可能的选择,但是,如果您问她是否曾经考虑过治愈,她会将她的病情视为一份礼物,并表示她永远不会寻求治愈方法。如果她这么说,你仍然可以在她父亲被击败后要求她寻求治疗,但她会拒绝,然后如果你再次询问,她会拒绝与你进一步谈论此事。如果你确实希望她在主线任务之后治愈她的吸血鬼,那么选择选项“你还好吗?”而不是问她有什么治疗方法。一旦你问了这个问题,她就会结束谈话,但你仍然可以说服她在她父亲去世后去黎明守卫堡寻求治疗。
