I feel pretty bad for leaving you guys on a mega cliffhanger on chapter six, so to help aid that a bit, here's how it was supposed to end.
4, 3 and mario defeat the big bads, splitting up to take them on one-on-one. they save their friends, and trap puzzles, dove and boopkins in some alternate dimension.
after that there would be some sort of movie night where they watch what boopkins' horrid movie would have been and laugh about it.
smg4 and smg3 got married a few years later too. I think I even made a fankid for a spinoff but it's scrapped because I've moved on from smg4 in general. thanks for reading it, though, and if any of you have any recommendations for any new fics then be sure to let me know.
