Accelerator watches Donnie for a few more moments. The turtle seems to have things covered on his end, so he turned his attention down to the golems that attacked him.

Even with his two creatures shattered into pieces, Accelerator glares down at their remains. Those things may be broken, but they're made of rock. Conglomerate rock. By definition they may be able to put themselves back together with whatever force - science or magic - that first created them. It'd be best to completely vaporize them, just in case.

He's mulling all that over when the arm comes flying his way. He doesn't notice, he doesn't need to notice, his reflection does all the work.

... Of course, that means the arm is hitting his ability and rocketing straight back in the direction it came from.
