A.this will be explained in the next main comic I'm working on. they only have one soul and usually no they go "offline" and don't remember what the other did when they were off xD they can talk to each other in rare situations mostly when pup is tipsy. Rex doesn't like Pup  that's why he's not careful and destoy his own body when he's in control :c and thank you for th ps ;;

2) Hi there. She saw everything by chance and had the feeling she should save when she saw what blue just did. If she wouldnt have been there and reacted like this, the chances of being able to reset would be bound to the last save point, and who knows when this was. So depending on how frequently she would actually save the reset would be possible. But since you like angst c: Viper dies. Blue witnesses it. None of the girls was able to reset without disturbing the whole timeline. Everyone would be grieving the loss of their friend and family. Blue never mentions he has the moment of impact recorded. His screen might be broken but the phone still works. He keeps watching the video of his best friends death over and over again. He shuts himself off more and more, his whole behavior changes completely. Theres no cool bean anymore. He died the day viper did. Eventually his mind would snap and hed go insane. To the extend that vipers never died and everyone around him lies to him. To which extend his insanity reaches noone really knows (kirsch wrote this since we do all together and I’m a horrbile writer xD)

3) there are 4 types of swapfell: Swapfell KH by khoppang; swapfell Red by the fandom; fellswap/fellswap gold by jot; and customyzed swapfell. the last one means that anyone can create their own version/interpretation of this AU. Mines (Pup viper iris/ Pupper Phyto Ruby) are my own swapfell. so yes I am the creator of these 2 ;; along with my best friend @kirschkernchen
