You mean the guy who is heavily wounded after having taken a bowcaster shot to the side from Chewbacca?
Remember how he's pounding his side constantly during the battle?
I'm not sure how much more blatantly obvious they were trying to get in terms of letting the audience know that he was not at 100%.
The fact of the matter is, the first time they encountered each other, Ren blocked her blaster fire and easily disarmed her and disabled her.
The "Mary Sue" people always leave that part out for some reason.
Here's Rey being easily tortured by Snoke.
Rey was not one of the major reasons why the sequels were subpar.
