[Michael does debate closing his eyes, only because he doesn't prefer to do so unless it's avoiding a flash-bang. Open eyes are a good step towards dodging something. But when she moves in they slide shut, little more than a long blink really, just because it seems polite. And really, they're in a force field.]
[He puts far more thought into the blink than the actual kiss, which is minimally returned because again, politeness. And maybe she reminds him a tiny bit of Fi.]
