Dean couldn't be bothered to hold in his laughter when he heard the chick's question. Well, he guessed she got points for originality. The last thing he needed in a stressful situation like this was a nut job. He was about to open his mouth to give her an answer when the other dude spoke. Ok...maybe he was dealing with two nut jobs.
"What the hell are you talking about?" he looked back and forth between the two trying to figure out what exactly was going on. "I mean, yeah it's Earth but it's 2007." He figured, though he'd never run across it, this guy may have experience some time travel....or he was just bat shit. The only thing he did know for sure was that there was no way it was 2010. Hellhounds were coming for him in a few months, if it was 2010 he wouldn't be here, time travel or no the demons would have come for him.
