You had always been on the smarter side, but never really got along with people due to your personality. You also tended to be smug about your abilities, and sarcastic around others. You wanted friends, you really did. You just couldn't seem to make any without changing everything about who you are.

That's why you were grateful for Donnie. The turtle mutant had been your best friend for quite a while, and you both were able to nerd out about stuff, your personalities meshed well, and you thought he was a good friend, and didn't feel like you had to change yourself to appeal to him.

You were currently hanging out in the sewers with Donnie, while his brothers were out doing... something. You hadn't picked up on what they'd said while leaving, as you were too focused on your current project that Donnie was helping you polish up and complete. You were happy he'd decided to help you out.

"So... This part can just.. Oh, you got it. Yay!"
