Q is startled by her playfulness--in fact, she just about gets a laugh out of him, certainly a surprised scowl-smile and an outraged expression! And then all at once he reaches out, and as he pins her close against him the lights in the house flash out for a few seconds. Just long enough to press a peck of a kiss against her mouth.

It happens without warning, in almost no time at all, and by the time the lights are on he's standing by the counter keeping his hands to himself again, one eyebrow raised in challenge. His elbows are propped behind him on the edge of the counter.

Retaliation. If she can play then so can he.
