Yes, I agree. But does he leaves just because Kylo falls? Movie strongly suggest Kylo did something terrible to Luke's foundation, which can be seen in Rey's flashback of Kylo standing (with what seems to be another group of people) next to a lot of bodies; which again means Kylo is no pushover when it comes to getting his hands into a fight. |
My guess is Kylo Ren murdered Luke's wife and he hid his daughter Rey on Jakku to proctect her...he then went into hiding just like Obi-Wan in A New Hope. The old guy who was murdered at the beginning holding the map was there to look out for Rey. Just my two cents for what it is worth.
