Traditionally, the Star Wars saga focuses on the Skywalker dynasty, meaning a Skywalker's incredible power with the Force and how he handles that power. Episodes IV, V, and VI focus on Luke Skywalker's ascent to becoming a Jedi Knight, while Episodes I, II, and III focus on Anakin Skywalker's descent to the dark side. Both Skywalkers discover that the Force is strong with them, learn how to use it, and assume their respective places on either side. Based on what Abrams has shown us in The Force Awakens, we're assuming he won't be avoiding the traditional Skywalker focus—and we don't think he'll be focusing exclusively on Kylo Ren, especially since his journey to the Dark Side is complete. Rey is the one the lightsaber called to, and Rey seems to be the one whose Jedi training the trilogy will focus on.

Also, the original lightsaber: Kylo Ren believes it belongs to him, and he even tells Finn that explicitly. But it calls to Rey. Rey is the one it flies to when the two battle over it in the snow. This is significant because only two Jedis have held the lightsaber before her: Anakin Skywalker and Luke Skywalker. So even though we're pretty positive she's not the daughter of Leia and Han Solo since neither of them even acknowledged that they had one, there's another possibility: is she the daughter of Luke? We hope we'll learn the truth of Rey's origins sooner rather than later.
