Mostly, it's the accumulation of "everybody is more than it seems" what bothers me. Too many characters are nemfected, a starborn, a secret denarian, wearing more than a mantle, under a thrall, a n ex-angel, and so on. When paranoia is THAT justified it became old fast. And losing one of those who were "just" what they seem to be, like Murph, hurts more when that is the case.
