Gar had this tendency to turn into a cat as the two of you were cooling down after an argument. He'd follow every your step or curl up over your laps and not budge until you'd be willing to talk.

Tonight was exactly the case. You two had run up into a typical couply argument but you need some time to come back to your sense to talk about the issue later. So, Beast Boy was now laying over your laps, letting you pet him and purring like crazy, since he knew how much you liked it.
