[Hunk nods. He'd been worrying about that himself.]

I'm trying to imagine they all just evacuated. I don't think we've found any signs of escape pods or ships or anything...but it's a possibility. We DID just get here, so maybe we'll find out they sent that distress call and then just booked it out of here.

[He chuckles nervously as if to say 'and won't we feel silly then.' He knows it is a long shot though. Why would you send a call like that and then leave? What would be the point? And it wasn't like they'd seen any indication of planets nearby.]
