She is, in part, being polite for the sake of giving herself something to focus on--having to keep her voice level, her words chosen with care and her demeanor controlled. It's a distraction for herself and one she's very familiar with. Familiarity is comforting, after all. Pippa is also trying very hard to remind herself that Rory isn't the only one with things to reveal and she'd be rather hurt (terribly so) if he reacted to her the way she's been carrying on. Granted, what she needs to share with him is...ordinary by comparison. Still, doesn't he deserve the very consideration she herself wants?

Of course he does.

"You pretend to be...human," Well there's something you never thought you'd utter in all seriousness, "You're not just pretending with me, are you? Last night, I mean...and the things we discussed on the phone a few days ago. You meant those things, didn't you?"

She keeps her palm pressed to his cheek, her eyes on his and she realizes that in those dark depths she can still see the warmth and gentleness she's come to know from Rory Stone. "Please, Ro...I need to know what you want."
