You Can Travel Forwards in Time, Too?

Sam has been spending a lot of time in the 1800s lately, so... So you can travel forwards in time, too? Yeah, I mean... I've never been to the future before. But time travel only works one way - towards here and now. The Eldridge is the only point anyone can travel towards. Sam: "For the love of God, please, if you could just try, please, I can't"
