{{OOC: Following on from the
emotional Three Mile Island between the Doctor and Martha.}}
The TARDIS is, to certain people's probable dismay, lurking in the Doctor's room.
However, this time, she's not lurking there to teach him a lesson. She's lurking there because she's still deeply unsettled by the fact that she ceased existing for a while, there, and she desperately wants someone to tell her what's going on.
She is, at the moment, a diminuitive blue box--roughly half-sized--with her face to the wall, quietly broadcasting a derivation of this universe's universal physical constants to herself. It's psychically "audible" in the room, but it's very soft.
