Leo might have moved in with his parents in Payton where his father gave him the mechanic job there. Chase, Jenna, and TJ might have returned to college/stayed in college (MA/MS/Ph.D. track). Carl might have found work in Payton/given college another try. Flynn might have passed away after contracting STD's from engaging in TSR unprotected; at least he'll finally be with Sydney. Like Echo routes, anything is a possibility within the multiverse which explains how socket face travels across space, time, and dimensions.
