There are things Jackie expects from the Doctor by now--mainly cheeky remarks and a habit of disappearing with Rose for months on end--but not that he'd be quiet. For the last hour he's just sat there by that window, drinking tea, letting Rose tell her own uninterrupted versions of everything they've done.
Jackie makes a fresh pot, and he finally looks at her. "Thanks," he says, though he used to turn up his nose at Typhoo. "That's lovely, Jackie, thank you."
What a smile. What a shine in those big eyes.
What a nightmare that must be coming.
