"Cool, that's way better." If he weren't so tired, that might have sounded sarcastic.

Tony frowns and glances back when Antarc pulls out their BSOD'd yimo to scowl at it, pausing before opening the door to the next car. "No, it's not normal. Your yimo's down too?" Tony pulls out his own to check it. It turns on, but clearly isn't happy about it. It lags and glitches out, and after a couple seconds Tony takes pity on it and shuts it down. "Yeah, that's definitely not normal. An EMP...?" Tony mutters, half to himself. "No, I would have felt that. Getting some weird interference with Extremis, though." He hadn't recognized it until now: he'd brushed off the extra mental strain and uncomfortable staticky feeling in his head as fatigue. "Maybe we hit some kind of electrical field. Probably blew the fuses on the train."
