Characters: Donatello, Michelangelo
Summary: Part 4/5 of the Toddler!Donnie AU.
First, second, third, fifth.
The day Rockwell finished the antidote (or whatever), Casey brought Donnie a little toy car. It was remote-controlled, and battery-powered, and Donnie’s eyes were the brightest thing in the whole universe when their human friend knelt down to show him the controller. It was cute, but mostly it was to keep him busy while Rockwell and April set up the lab—putting the scene of the accident back together, down to the last broken beaker, and getting all the new chemicals ready.
The whole thing kind of reminded Mikey of the Kid Flash origin story, Barry Allen recreating the lab accident that gave him super powers for his girlfriend’s nephew, and whoops, who knew lightning would strike the same place twice and give lucky little Wally West a tap into the Speed Force?
April assured him there would be no lightning involved in Donnie’s case. Which was good, ‘cause comic books made it pretty clear that lightning hurt.
“Mike,” Donnie called from the other side of the room, smiling ear to ear. “Mike, come play with me!”
Man, Mikey was gonna miss that. And he was gonna miss the way Donnie put his arms out to be picked up, and the way he’d giggle behind his hand at all of Mikey’s jokes, and sit on the counter to help him make lunch, and drink in everything he said like a wide-eyed little sponge.
But Mikey missed his big brother, too. So, since he was gonna miss him either way—
“I’m comin’, munchkin,” he said with a sideways grin, hopping to his feet. And if the look his father gave him on his way by was a little too knowing, a little too understanding… well, whatever. Sensei always said he had a great imagination; Mikey was really good at pretending.
And he could totally pretend like this wasn’t gonna hurt.
