Hardly surprising that Kylo deflects these shots easily. I am curious though why he didn't immediately do the time-freezing thing on Rey like Poe was hit with. If the goal is to stop her from completing her training, death would be a very permanent way of doing so. Maybe Kylo can't actually do anything else to people at the same time? With no troopers nearby to grab Rey afterwards, they'd be in an awkward stalemate of sorts. It could also be a terror thing to show just how outclassed Rey is before trapping her in frozen time; that would fit quite well with how Sith all seem to behave in the movies.

Also curious is why the GM is narrating the actions. The players know that Kylo is played by Sally, so there's no need to hide that fact. Perhaps Sally had to step away for some time; I've seen some GMs play a PC's characters before when the PC had to leave for a bit. They couldn't (or wouldn't) give the character the same amount of personality as the player due to the need to manage all the other NPCs, so minimal descriptions were usually the go-to method. This usually only happened when the missing PC's character was integral to the plot as well. In-comic, something like that would handily explain Kylo acting strange here.
