Warning: spoilers ahead for Fear The Walking Dead season 8, episode 1.Seven years pass during Fear The Walking Dead season 8's premiere, and plenty of offscreen action happens during that gap. Fear The Walking Dead season 8, episode 1, "Remember What They Took From You," begins in the immediate aftermath of season 7's finale, with Morgan and Madison busting into PADRE looking to reclaim the captured Mo. The story then quickly skips ahead seven years. Not only does this represent one of the biggest time skips in The Walking Dead franchise history, the jump also brings Fear The Walking Dead broadly in line with The Walking Dead's ending, finally lining up the two shows.
