I find it rather curious that the original corpse of Angelique, dead for six months, was revived and "rewarmed" by a slight touch from her sister.
However, now that this body is "living" again, when it has an attack of the cold, it seems to need to kiss and really suck the warmth from the other person in order revive again.

By the way, yesterday someone was speculating on what Angelique would have done if Daniel had been the next person to enter. I started wondering what she would have done if it had been Quentin. She clearly has other plans for him - at least at this point.
