Donnie's liked you for quite a bit, even though you're not as into science as he is. No one's as smart as him anyway, though; his favorite thing to do is invent, to make things that help his family. Yet another favorite pastime of his?

It's to watch your band play. At first, it started off rickety, but Donatello gave you pointers. And now you're playing at a club, and wow.

He just got here, and he's already beaming at how you're so energetic. So happy. He can feel his small tail wagging just from the joy that radiates from you, the way the light hits you just right.

Until he realized you were looking at someone in specific. Someone in the crowd that wasn't him. And he faltered, eyebrows furrowing because that wasn't right. Like something miscalculated. An error was made on your part, surely.

But you smiled at a person, kept staring at them. And bitterness swelled up in his chest.
