Blood Plus, the anime? *SPOILER*?

Okay, so I'm at the point in the anime just after the year break, where Saya comes back and is distant and somewhat stuck up. Does she stay like that? I don't want any big spoilers, but if she doesn't get better, then I don't know if I want to continue the anime. She and Hagi were my favorite characters, and I kind of got to the point where I only watched for them.
