yeah so sloane and luther found each other, got remarried, and luther is the world's greatest stripper and sloane is a physicist. diego and lila went to couple's counseling and are doing better than ever. diego quit his UPS job and started a food truck selling street tacos. lila teaches mixed martial arts at a gym. allison is continuing to pursue her passion for acting and raising claire. maybe she and ray even find each other again. klaus falls in love again. he misses dave, but not everything can work out. he overcomes his hypochondria and can have fun again. five retires. he's going to learn who he is without constantly having to be on a mission. ben... is honestly probably still a bit of a selfish asshole, but he starts working on himself. maybe he gets some other kind of tech or salesman job. viktor may have been dumped by every woman in town but that doesn't mean there aren't any men for him to date. he's got his bar and his life, his violin, and maybe a dog or cat.
they're all adults, finally. they get together enough to never miss each other, but not too much so they all get annoyed with each other. with reginald dead and their powers gone, they can all finally start to move on from the past. they're no longer the children they used to be. they no longer have to be defined by their childhood and where they came from.
