Remember how at the end of season three, three members of the team were left stuck in the Cretaceous period? Man, we thought that was going to be the series finale and we were so incredibly upset about that cliffhanger of an ending. We may be even more upset when the new season picks up and our time-traveling friends find their role at the center in jeopardy. You have to expect that sort of thing what with getting lost in the past and people thinking you'll never return, but that doesn't make it hurt any less. Can you imagine fighting off dinosaurs only to have to fight off bureaucrats when you return? That's hard.
