Continuity mistake: When Sarah resuscitates Cyclops, they are by the edge of the swimming pool. When the shot changes to Cyclops blasting through the screen door, the pool is nowhere to be seen, nor is the puddle of water that was under Cyclops in the previous shot.
Continuity mistake: The layout of the living room in Killgrave's house varies depending on the shot. Sometimes the half-circle couch is next to a staircase and sometimes it is not. The piano is also in a different spot on the floor each time it is shown. There are also chairs that appear and disappear throughout the scene.
