Mikey lights up as Donnie agrees. He is still a little run down with emotions and he hadn't really expected Donnie to say no. (Though, if he had, Mikey would have been crushed).

"I promise I won't be too clingy!" He says cheerfully. They both know it's a lie but the heart is there. At least he won't take up too much bed space, but that sure isn't the issue here.

"So, does this mean I can call you "little bro" now?" A phrase he absolutely will not use, he wasn't a fan of being called little by Raph and Donnie is still his big brother, no matter what. But c'mon, it is a little funny and he has to get Donnie's reaction at least once.
