It isn't because Tom's trying to avoid Albert's feet that he takes Felicity's knife to the gut, but it is because of his instinctive dodge that the blade sinks as deep as it does, ripping through muscle and organs alike on the way in and near-sawing through the viscera back on the way out. Blood spatters across the wall in a straight line that seems nearly unnatural, like a laceration in the wall rather than in Tom's body.

He throws a backhand at Felicity and continues his forward momentum past her and under Albert, hurling himself at a transportation chute that'll take him upwards or downwards or anywhere else. It'll take him to escape, and that's what matters. He grabs the wooden necklace around his neck and a flash of heat and light from his palm melts the control panel right after he's set the chute into motion for himself. He is, very suddenly, beyond their reach.

But the wound is fatal, and the amount of blood over even that small distance between them and the chute should be enough to tell them that.
