The aura around Storm brightened at the little glow, not as bright at the Unicorn, but enough to provide a contrast. He smiled, bringing his gaze away from the floor, and focused on the subject at hand.
"I don't mind gray either." he motioned to the little twirl of cloud, as it's color deepened to a neutral tone, sinking away from the white glow and just sort of- contented, at this point. "I'm sure you'll come up with something, though. And I'm sure I'll be delighted, now-"
He motioned a bit towards the door. "I really should be going. I wouldn't want to take up all of your time, and well- I do have places to be, unfortunately."
He was sincere. The Storm cloud really did need to move on, but he was trying to be as polite as he could. Really, it wasn't that he didn't want to be around the Unicorn. In fact, he could probably spend all day there, watching him work, and well- looming like he did. But it was most assuredly, time to get moving again.
