"What?" is a predictable response, followed a moment later by Kaidan pivoting away from the treacherous patch with a "--Shit. Thank you." that's managed to mingle soldierly profanity and innate Canadian politeness. (Clearly the problem is that ice patches on rooftops don't mesh well with hockey skates, or he'd be just fine.)

The crunch and hiss of shovel against snow is followed by a few more scoops of it getting tossed off the side of the roof, and then the sound pauses as Kaidan uncovers a universal truth about home maintenance:if you start a simple project, you're going to find another project after that. "...looks like there's a hot spot up here," he reports down to Zarya, in case she's as interested in the roof as he is. "Must've melted some of the load last time there was a warm spell. Do you know what they use for insulation around here?"
