Donnie stared at him, still struggling with the whole idea that anyone had any interest in what he was doing. That was one thing, wanting to be taught.... Well, that wasn't exactly something that had ever happened so he was surprised by the mixed thoughts that were prompted by this new request. It had always been his niche, after all, fixing things, creating things. Raph's was being strong and smashing things, and being the leader. Leo was the face guy, and apparently also leader now, which was still weird, even if he'd seen it in action during their trip to Iskwiyac. And Mikey, he was the wildcard and his attention was never in one place for very long. ...was it wrong to mesh all the Mikeys together?

He hadn't too much time to figure out if he'd just felt somehow threatened by this request when Mikey followed up with things that he'd been certain they'd covered before. And it was strange, but relieving to see that he wasn't chewing on himself or worrying at something. This was Mikey who had finally figured out where he was supposed to be. It made Donnie feel guilty about his earlier thoughts, even though they lingered. His smile felt forced, but he hoped it didn't look like it.

"I thought we had that figured out already but, yeah. That's true enough. Glad you came to your senses."
