The main spoilery thing I wonder about is a blend between me remembering some things, and not enough. I'm wondering about the attack on Ozymandias, wondering if it was staged by him and he had the poison at hand and forced it into the guy's mouth, to keep suspicion away from him. Or if it was someone else who knew something, and tried to put a stop to it. I can't remember, or even remember if we find out. I

'm leaning toward the former though, if only because the gunman shot at the wrong target when he had the drop on them.
