So does Sans still like Sci-fi and space stuff?
Yep, he still loves nerdy science and space stuff. Not Canonswap Sans levels of love but, he still has a deep interest with Space and has theories about what lies in the huge and unexplored reaches of space. He talks about it quite a bit with Alphys and Undyne but, not so much with Papyrus, Azzy, or Toriel. Sans even has a copy of a game called “Spacebound” in his room, likely in his dresser or closet... He also has dozens of empty Ketchup bottles and a broken controller too with a cool fire design but, most of the face buttons are broken off as if it was thrown against the wall multiple times and on the back it there is Papyrus’s signature... that’s written in Red Marker... Yep total Nerds...
