WHERE THE HE K IS THAT GIF OF THE MACHETE COMING OUT OF THE CLIPBOARD FROM
It’s a deleted scene, one of the ways Ginger and Merlin try to jog Harry’s memory. He’s spread out, limbs tied to horses. Merlin can’t bare the sight of Harry in so much pain, so he unsheathes the blade and cuts him free.
(If I remember right, Merlin doesn’t cut all the ropes, so Harry ends up being flung and dragged through grass as the horse he’s tied to gets spooked.)
