After significant trauma that prevented blood fom reaching the brain, it would take twenty-one seconds for oxygen starvation to take place. The cells of the brain would die, causing irrevirsible damage, and soon after, death. Oxygen starvation. Stein knew all about it, the way it worked, he'd drained some of his victims dry to study their brain slowly ceasing to operate. He needed to get up, to move. Find some way of replacing his heart, or directly oxidizing his brain in some fashion. Whatever the cost, he needed to prevent his brain cells from dying out, or it would all end.

Stein fiddled with the teleporter, blackness filling the corners of his eyes, His fingers were heavy and hard to move, his injuries taking a massive toll even on his body, modified to be as durable as possible. He needed to take his time, if he teleported to the wrong location and had to try again, he wouldn't have enough time to do anything of importance before he died. He selected the coordinates correctly, even without looking at the device. He'd used it for years, and his familiarity with it's workings was the only thing that let him perform this action in such a short amount of time.

Stein was in his lab, bleeding out. Moving was a struggle, his muscles screamed at every flex of a muscle. He inched towards the operating table, knowing he had plenty of hearts in reserve. At least one of them would fit him. He slowly worked his way towards it, , eventually simply dropping forward, his limp body crashing onto the smooth metal surface of the table. It was cold, but peaceful, the embrace of death finally reaching out for him. It was comforting, in a way, standing at the end, finally freed from the sins he had committed, at least in some sense. The pain couldn't haunt him in death.

He needed to get his body up on top of the table, Mia's pet wouldn't be able to operate with him in this position. He shook himself from the cold calmness that had fogged his mind, willing himself to move onwards. He still had things he needed to do. He still needed to avenge his wife, and Mia still needed him. He couldn't die here, not so long as Drac continued to draw breath, and Mia still wished for him by her side. He couldn't leave her again.

Stein reached out, grabbing onto the sides of the metal table, slowly pulling himself upwards, his vision foggy and blurred with blood and tears, streaking freely down his cheeks as he wept almost inexplicably. He pulled himself up, hardly able to think in a straight line. His brain was dying, it was slowly shutting down his systems, preparing for the end. It simply wasn't recieving enough oxygen to fundction properly. He couldn't recall the last 2 seconds of struggle, but he worked his way onto the dissection table, breathing erratically.

Stein watched as long, spindled arms reached down from above. They took ahold of his wound, moving with calm precision, slicing through tissue in order to discover and solve the problem. Stein couldn't care anymore. His mind was incapable of caring at this point, blacknes filling him, a coldness sweeping over him. Everythign was dark, as the sound of a bone saw filled his ears. His last thoughts before falling into unconsciousness were a question. One he had asked himself many times before, in the moments he faced death such as this, the moments the agony became unbearable. Had he made the right choice?
