'Compromise'
"Don-"
"The bike will be done, Raphael, as soon as I'm done with Mikeys game."
"Yeah, but I need it for-"
"If you need it earlier, then the tools are over there. You've watched me fix it enough, I'm sure you remember."
Raphael folded his arms. "Sure, but I don't trust myself not to screw it up. And then I'll have no bike and-" He paused, considering the possibility of no easy way to leave the lair and get the adrenaline rush he always seemed to need.
"I understand, Raph, really I do. But I'm busy. But, I tell you what, if you try fixing it by yourself I can come and check the bike over before you actually ride it. That won't take to long."
Raph nodded, eyes lighting up. "That's sounds awesome, Donnie-boy!" He picked the tools he needed and ran from the lab.
Donnie shook his head fondly and went back to Mikeys game.
