Fenrir had keep his eyes and nose on Nathan, not quite trusting him. He didn't smell quite right, almost as if he bathed in keratin and way more of it than any other race. He wasn't quite sure what it meant, but he knew it wasn't normal. But, he was then distracted by another, probably more important smell, explosive compounds, and he was smart enough to know it generally good not to be around those. He was half-tempted to just jump out of the window, not knowing how powerful the charges is and not wanting to find out.
He slowly walked over to the window, no need to cause a panic and possibly set them off anyways. He was this close from jumping out until he remembered why he was here. He then sighed and said under his breath, "Well, there is worst ways to die." He then heard a short telepathic message, "You too Fenrir". Which, he was pretty confused by nevertheless, he knew something important was going down. He then followed Nathan's scent back to the group. "What is going on, I smell something, maybe it is gunpowder, maybe it is something else, all I know is probably going to explode."
