Probably a good thing Donnie managed to hold his tongue on what would have definitely come off as an insult, although who knows, maybe making Accelerator mad would enable him to hit harder?

...Yep, that really is the esper's hardest. Thankfully Donnie keeps his face neutral as he does a simple shift, deliberately slow so Accelerator can see what he's doing- and also so as not to let him go sprawling on his face.

The turtle angles his bō to help slide the crutch along rather than meet it directly to halt its momentum. He's also ready to grab Accelerator in case the esper looks like he's going to fall past him.
