"Well, I think the definition of alien is a little muddy around here," Sam said wryly. "Your galaxy might not be any farther from Earth than our home dimensions are from this one. We're all on a different planet now, technically speaking. Us refugees, I mean."
He paused for a moment. "Sentient World Outreach and Research Division, I think. Or something to that effect. And SHIELD is Strategic Homeland Intervention... something... Logistics Division. I can't remember what the E stands for." He ran a hand through his hair. "Well, I should say SHIELD was. Past tense."
Curling his fingers around his drink, he smiled a little. "We just started talking over the network. Found out we had a fair amount in common, especially in regards to... the way we reacted to ending up here and trying to figure out our new world, so we kind of agreed to watch each other's backs. It's always good to have backup, when you're wandering around in a new universe."
