It's probably a very good thing Accelerator has already whitelisted Donnie. If he hadn't, he'd have to do it right now. There's no way he could be walking around with a little kid like this with the risk of killing him.

He enters the restaurant, holding the door open for Donnie since his hands are full with the cane, then approaches the counter. The place isn't too busy, thankfully, and he orders a chicken nugget happy meal and a coffee. It comes with a toy that Donnie can pick out, some little plushie that Accelerator quietly thinks is kind of dumb but something Last Order would go ballistic over.
