Hesitating too long to answer what he was doing, though, would be suspicious, and he couldn't start admitting that he felt or wanted anything now, he had been doing so well, so he bought himself some time by spinning around in front of Keith with a flourish, legs extended and fingers spread daintily to ask, "Isn't it obvious?" He brought his hands behind his back to bow a little closer, where he might have been looking through his lashes coquettishly if the mask of the Iron Man wasn't so impassive, so he could purr, "I was waiting for you."
