1. Maybe Rey isn't exactly untrained - perhaps a survivor from where Luke trained jedi. 2. Perhaps Rey is Luke's daughter and is a natural - what if the force is even stronger with her than we yet know? 3. We learn that Kylo's training was not yet complete - cut him some slack lol 4. Kylo's conflicted - what happens when he's not? 5. Most importantly, Chewy's gun appears to be rediculously powerful. Han loved it. It apparently goes right through trooper armor, knocking them back about 20 feet and/or slams them into the nearest wall, killing them dead. Well and here we have one way past enraged Chewy shooting the crap outta Kylo, who doesn't appear to be as armored as a stormtrooper, so Kylo buckles but does he go down? NO. This dude hunts down Finn and Rey through a fricken blizzard, bleeding out onto the snow and does he cry about it and give up his persuit? NO.He keeps punching the wound and whoops Finn's ass. Finn would totally have died right then and there if Kylo had wanted to finish him instead of turning his attention to Rey, and would have died from his wounds if he hadn't been rescued. So, the wounded Kylo continues on and fights Rey as well! He gets bested but survives all that too. Dude's a badass. Cant wait to see what they do with him.
