As Wyatt comes up from the ground Grey recognizes him immediately. His killer from the previous arena. He'd had help then, though. Not this time.

"Hello!" He says brightly, despite the fact that he looks like death warmed over (and feels like it too). His forehead is dripping with sweat, the edges of his hair wet with it. Switching the piece of re-bar to his cybernetic left, he draws the folding knife with his right, flicking it open.

Watching the other man closely, he moved with him, unwilling to give him that opening. Not easily, at least.
