With his head still messed up from recent events Sarge would have assumed that he was hallucinating in some form of twisted flashback, if he hadn't seen everyone else react to what most definitely was an explosion that was loud enough to make his ears ring quite spectacularly. His eyes automatically turned to Rodeo, who didn't scramble towards it like everybody else, so of course he didn't, either.
