During the chaos, he saw the red head and the black haired one helping the now horned girl with the bloody ice in her chest. He slowly inched over with his machina, charging his weapon up as he placed it in his machina. He strolled over to see the red head was the only threat; and not one that he'd see as threatening seeing as he had range on her. 

"Girl, I never quite caught your name, but I can see this person is precious to you, though I see her as a potential threat to a degree, I no longer see her as very active, and because of that...-" He cut himself off, he wasn't about to go into too much exposition. 

"Just hold her steady..." Cassius ordered. 
"Master, that shard contains a large portion of her blood..." Helios said trying to be discrete despite everyone already able to see what it was. 

Cassius looked at Eva. "No offense, but you're going to make it worse by closing the wound around the ice, what you all should do is move her into a hut away from here where we can patch her up, and melt the blood so it can be filtered back into her body. Though I'm sure they appreciate the effort." 

"There is something I can try here, seeing as my machine is pretty much a medical one. But... if it were up to me I'd do as I just stated. Melt and filter the frozen blood. Pretty hard to do in debris." he commented. 

Cassius folded his arms as he looked over the four. [i]A moment ago she was a big threat, and now they want to save her, so if I am correct as I previous guessed, she is important to them, and if my assessments are correct, she was possibly not in control seeing as her aim dramatically shifted and transformed her body... truly terrifying...[/i]

"Well... there is one more alternative... if there is no breech in her back, you can lay her flat on the ground and slowly melt the blood from the root- where it is impaled as it seems, and then I could heal over that." He gave his last option to the group.
