I don't usually comment on things I read now, but this one deserves a WTF comment cause I need to get that out. I never in my wildest dreams ever thought a scenario like this would ever happen.
He really is his bride (probably). He has a big mana capacity so that when he and Glunn do the deed he won't die from mana overload (my theory). Not a spoiler but just a theory.
Conveniently, he easily gets hives. So the hickey problem would turn to "oh,it's just hives not hickies".
