I'm pretty sure he knows what Quick Claw does who he wouldn't have used it. We needed confirmation that that's actually the move he used. There are other possibilities, such as not noting that maybe the latios may have also used Quick Claw, or maybe the Latio did use priority. Or maybe it was just a bug. I use to often get these types of glitches happening to me because of the lag I got from my old second hand 3DS
