Ed was mostly too damn stubborn to pass out was really the only reason he hadn't. He kept going because he'd had no choice. Al had needed him to, but now Al wasn't there. Now he had no choice but to slow down apparently by a familiar hand. A pair of golden eyes flickered upward in pure annoyance at the colonel as though he wasn't sure why this was happening. "M'fine." The hand that barely touched his wound however proved otherwise. He coughed as he sat back, muscles contracting in protest at the movement.
"Homunclus." He wasn't sure why the Colonel didn't know, The last thing he remembered was Envy and a mixture of Lt. Ross blurring into his vision before hitting the ground and being kicked repeatedly. He was breathing, but it was ragged and painful to do so. Sitting wasn't really that helpful, but it was better then standing especially if there was a brick named Mustang in his way. Ed gave him a forced smirk through the obvious discomfort he was feeling. "Tried to force me to make a philosopher's stone. Told them to kiss my ass." He'd learned a few things in his time with the military at least. The philosopher's stone was not something to be taken lightly, he knew what it meant now.
"S-something happened anyway. I couldn't leave." His blood had triggered the circles already created in that room but that part was a bit of a blur to him. He had a few broken ribs ontop of everything else, but the bleeding wasn't internal at the least. No blood from the mouth-it was all from the wound Roy pawed at. Ed could feel his vision struggling to cooperate, struggling to cling to the waking world but he retaliated out of pure stubbornness.
