Continuity mistake: During the throne room fight against the red-armoured guards, one of them splits his weapon into 2 blades. In the shot where he gets Rey into an arm lock, the blade in the guard's left hand vanishes from the scene completely, in the middle of a shot. The hand that held the weapon is obscured by Rey's body at the point when the disappearance happens. It could be that the actor dropped it (a strange thing for an elite fighter to do), but then the blade is nowhere to be seen on the floor in the wider shot when Rey kills him.
