Sam was used to ignoring voices in his head. More recent had been Schmuz, of course, but there had been Meg, too. Hauntings, too, where the ghosts had tried getting into his head or Dean's. It meant that the voices that were trying to get in, the ones that he honestly had no clue WHERE the hell they'd come from, were easy enough to ignore. Besides, with the renewed attack, it wasn't like he had time to really think about it.

So he ignored the jangling in his mind and added his guns and torpedoes to the attack, doing his best to keep the Shrikes away from the downed mecha, staying in behind the Quarter to add coverage and avoid the cannons.
