Let me rephrase Steven: he's a more significant nobody than the other nobodies...if that makes any sense.

My view of Steven has always been that of a plot device. He's the one who initiated the argument that forced Lizzy into her predicament and his refusal put a man of action in Angel in the guard room. I understand how that looks like he's guilty, but I really think he's just a way to get the story to move along for our main players.
