Wegnus, having overheard the conversation with the newcomer, attempted to listen in into what the man by the door would say to the newcomer. He could already tell that it was about ichor, because he heard 'kingdom of the gods' in the other man's sentence. As he was trying to listen, he hid the labeled flask in his robe's left sleeve. Wegnus really didn't care about dying. It's either he gets separated from the other person in him, or death. Or maybe another, bigger problem.
