This week's chapter answers some key questions. I think it'd be better off if you aren't spoiled. You have been warned.
! Dawn Roar wonders why they were given the order and what Helbram is up to. Jericho listens in while hiding. Meanwhile, back in the forest, Gowther reveals that he made the monster wear the armor to suppress its powers. Sins begin fighting while Gowther carries Pelio to safety. Meliodas picks up a sword on the ground and uses a black flame attack, which Ban recognizes as what gave him the scar.

Gowther comes back and attacks the monster and Ban frees Meliodas. Meanwhile, back at boar hat, Cain from Byzel visits the bar, and Elizabeth opens the door. Cain is in disbelief, and as he looks at Elizabeth, he exclaims "Liz!"
