Quick recap
Strahm survives the water cube by giving himself a tracheotomy, but Hoffman is the one hailed as a hero. Suspended, Strahm starts digging into him. Flashbacks show Hoffman's origin: he killed his sister's murderer in a copycat Jigsaw trap, and John found out and forced him into service. Meanwhile, five strangers tied to a fire go through one trap after another; only Brit and Mallick make it to the end, once they see they had to work together. Jill receives a box from John. Strahm corners Hoffman, but walks into a glass box and is crushed by the walls.
