>>393270930 seconds in, the MW crew is confused because they were supposed to be at their destination in 10 seconds. They begin to get really worried at 1 hour and no one has helped them yet. Curly with his experience as ship captain is able to keep all the passengers in their carriage calm with his confidence. Swansea is confused at why his hangover isn't going away and passes out at frequent intervals.
They all soon realize their bodies are "stuck" in the state they boarded the train and it'll be that way until they somehow unboard. Several days in, Anya considers attempting until she hears that someone a few cars down tried and couldn't die no matter what. Curly continues to keep morale boosted in their carriage but things aren't looking so good next door as people start intentionally mutilating themselves for any sort of stimulation and breaking into other carriages to attack people.
Jimmy and Curly inevitably get into an argument where Jimmy gets fed up and pushes Curly into the next-door carriage where he gets chopped up and all his skin ripped off by the suicidals. They somehow manage to retrieve his body in pieces and he's still alive but can't talk anymore.
Jimmy tries to "fix" the situation by sewing Curly back together but he can't find every limb so he starts attaching parts of random passengers, creating a weird amalgamation Curly-kaiju thing that barely resembles his original form.
So morale in their carriage is at an all-time low and people break down and start splattering themselves and eachother on the walls. Poor Daisuke is the first to join the walls, Swansea and Anya follow suit, Jimmy goes "fuck it" and mutilates himself mixing his insides with Curly's so they'd "never be apart"
They stay that way for like 2000 years until the WARP cleanup crew shows up, resets their bodies to their original state, wipes their memories, then they all leave the train going "Wow that really was 10 seconds! Technology sure is amazing."
