I would think that the technology for cryo freezing people would have been newish by 1999, so there probably aren’t too many people from before then who woke up in 3000. There may have been a few people who froze and unfroze around the same time, so he may not be THE oldest, but I think that he’s the oldest person in the series
Ah, ok, thank you for confirming I didn’t just black out a big chunk of that episode or something, cuz I read Steve Castle in your comment and I was like…who the fuck is that? He had a name??
