Daniel had been waiting to see what happened, the idea of actually attacking the other trainer never occured to him, he'd been to rougher places (Orre has some epic colosseums with unusually high prizes to try and draw people in, but one visit is enough to see why they have to offer such good payouts) but people were generally smart enough not to try anything once their pokemon were down. 
It seems the guy who'd been in trouble earlier has just found out why too. Where had that Mr RIme even come from. The world warped and the masked man was gone before Daniel could act. 
He rushed over to the downed man "You alright there?"
