"There's a humming under her skin that never fully goes away. She might forget, sometimes for days at the time, sometimes for weeks if she's lucky, but it's always there in some way. It fluctuates. There are times when she can ignore it and other when she can feel her cells vibrating to the point of bursting."
Rose's still human. Mostly. Doctor isn't.
I really wanted to write some tenrose hurt/comfort dealing with the aftermatch of well... Rose becoming a cosmic deity for a moment. Also, there's not enough portraits of the Doctor as an alien he is. I hc him as a creature existing beyond three dimensions so he looks human, but trurly isn't, so his "true form" literally shines through when in distress or other strong emotions. It's normally not in a visible spectrum for humans, but Rose isn't just human anymore after looking into the heart of TARDIS, so... That happened.
