The Doctor looks shocked and appalled at Iman's vague phrasing and gesturing re: the TARDIS. "Ye-es," he says, which covers two of the three questions, neatly answering the third as well. He can see where Iman is going with this line of questioning, and although he'd already had the thought, he still bristles the tiniest bit at Iman just assigning his living space to a child. Who just comes into somebody's home and does that? But though he may find fault with the execution, Iman's got ahold of the only real solution. "The TARDIS has plenty of space, all the amenities." And is a sentient ship with whom he is on somewhat unsteady ground, who should probably be consulted, but isn't being. Anyway it'll be fine. "As well as some psychic capabilities which may offer protection on that front, too."

He turns his total, stern attention on Callie once more, and points for good measure, like he's delivering some kind of verdict. "You. You stay here for now. You can find something better later, if you like. But you can't just sleep on park benches until then, eating breadcrumbs like a pigeon," he preemptively argues. This is America. Bench-sleeping is probably highly illegal. And her other options are even worse. "Don't argue, it's settled." If she draws the attention of her brother, it probably won't matter where she's staying anyway.
