Well, to his credit Emlyn [i]was[/i] surviving. He'd hardly been able to move from his previous spot, remaining back-to-the-ground with Mirror held defensively above him. The Itzamna only paused in its assault every few moments to try and snake a talon around, or over, but Emlyn had retracted almost his entire form behind the shield. This was a little less than the best situation he'd ever been in -maybe the Grimm would tire out? He must've looked ridiculous laying there like a turtle, and if his life weren't on the line, the embarrassment would have been deadly. 

He faintly heard the dying screeches of the other Itzamna, and that brought a sliver of relief to him. On top of that, he wasn't the only one to take notice; the Itzamna hurling slash after slash at him paused for a few terrifying moments until it screeched, directed away from him. Emlyn chanced a very brief view around his shield, and realized the Grimm was gazing off at Auriel as he slashed off the other Itzamna's tail. 

Emlyn saw his chance, and took it. He rolled to the side, out from underneath the beast, and retracted the center from Mirror. Springing to his feet, he whirled the chakram around and tore through the front of the Itzamna's neck. The thing tried to screech again, but the sound wouldn't travel past the gaping wound, and after a few flails of its arms, and its tail, it toppled to the ground, dead. 

"[i]Yes![/i] Holy shit we did it!" he yelled, jumping up in excitement. He gave the nearby corpse a swift kick, scurrying a few steps back when it twitched a bit. He recomposed himself though and grinned in the sinister way that was his default. "Oh man, we absolutely [i]wrecked[/i] them!"
