But we were very few, and now there are millions of people playing Dawnguard now. If anyone can tell me how to get Serena to marry you. That'd be great.
I'm currently trying to have every dialogue option with her and choose all the nice options. And I'm not sure if you must choose the Dawnguard side or not. But there is a specific set of options you must choose to convince Serena to turn back into a human.
I'm also glad if anyone can tell me how to do these things.
