Rey won a lightsaber fight without any training at all. This indicates that she is special and incredibly strong in the force and it begs for an explanation.
The explanation is chewie had just shot kylo ren with his crossbow and he was quite injured. You can even see blood falling out of his suit in several shots.
Sorry, I don’t buy it. Yeah he was injured, but it was still someone trained against someone untrained.
Obviously the only way to test this is for you to go get trained in the Force, dahmaged will shoot you in the side, and then you and I will have a lightsaber fight. Let’s do this.
