If Leo ever gets mad enough to murder one of his brothers, it’s generally Raph — though sometimes it’s Mikey, but Mikey can almost always get Leo to laugh off the worst of his temper before Leo does something he regrets.
Wanting to kill Donnie — that’s new.
"Why — how did this seem like a good idea, Donnie?” Leo wishes, ever so briefly, that he had a nose, so he could pinch it. He so badly wants to pinch his nose in exhaustion and frustration. “Usagi’s not — why, Donnie, why?”
"He said he was tired!" Donnie says, guilty and shrinking ever deeper into his shell. "And he asked me how April and I managed to pull long hours in the lab and things just sort of…snowballed."
Leo levels a bleak stare at his brother. “Snowballed,” he says. “Donnie, Usagi has not slept in almost thirty-six hours. He keeps —” Leo swallows what he was about to say, because so far they’ve managed to keep Casey away from the most obvious joke of all and Leo wants it to stay that way.
"He won’t stop," Leo finishes.
"I’m sorry," mumbles Donnie. "I didn’t think he would drink the whole pot. Honest, Leo, I’m sorry."
Turns out it’s just as impossible to stay mad at Donnie as it is to stay mad at Mikey, especially when Donnie is hunched over, with eyes wide and apologetic.
Leo sighs and bumps Donnie’s shoulder with his own. “Just don’t do it again, okay? His crash is going to be bad enough without him turning into some kind of caffeine junkie like you and April.”
"We can quit any time we want!" Donnie protests, just before a loud crash from the kitchen sends them both sprinting out of the lab.
When they get there, Casey is picking his way out from the pieces of Splinter’s third-favorite tea set, and Usagi is trying to hide how badly his hands are shaking in his sleeves.
"Dudes," drawls Casey, "you gotta find a way to calm him down. He just keeps going and going and —"
No, Leo wants to scream, but Casey’s eyes have already lit up, and that’s it, that’s the end, Leo is doomed to a lifetime of jokes about Usagi’s battery.
He would kill Casey, but Usagi looks at him with mute, pleading eyes, and he decides to save murder for later, and get his friend to bed.
