"Oh man, don't even worry." Sulu couldn't give specifics, but that didn't mean he couldn't at least give Ianto some reassurance there. "I mean, every era has something exciting in it, you know? You're at the end of the 20th century, right? Because the 21st century starts a lot of chain reactions that lead to this." Some of it wasn't good - terrible, even - but he was sure that Ianto's timeline hadn't developed the same way his had. "So it won't be boring." Maybe it wouldn't be "colonizing planets" exciting, but still.
