Green and blue. Earth, essentially. Everything there, from Eva's turtlenecks to her family, to the wind whistling past the half-opened car window. The Doctor thinks those are all perfectly good reasons to hold onto herself and remember how human she is.

The Doctor's own smile is wry. Eva does have a way with words, even in a dim prison and surrounded by thousands of Sobek's faithful.

"I'd say we're almost out of time," the Doctor says, and somehow he makes that sound like a good thing. He reaches out to pat her hand, his voice barely above a whisper - Eva can hear him, but the guard posted at the door can't. "Have you and Vala found anything about how to stop Sobek himself. Anything we can use to separate it from Daniel."

He'd had that one psychic connection with the beast his first interrogation session, but after that, Sobek had made sure to say out of range, knowing full well than anything within touching with the Doctor was risky. Quite right, too! If he'd had more time, he thinks he could have dug in deep into the False God's mind, only "could" isn't what they need right now and that's why Vala and Eva are in such important positions. They can move about, far more than he or Jamie can. The Doctor shifts again, slowly, mouth thinning into a line as the dead heart continues to sit there, his face turning toward Eva's.
