Jasper isn't interested in being a leader, she's interested in following the strongest. She's too insecure to be a Diamond-level leader. This is literally the Roundtable's theory. >>115200991
Jasper got a much better ending than Alura. She got the fight of her life, got to come back from near-death and now clearly lives in a place with many other gems instead of being forced back into the woods. That means whenever the series comes back we don't have to start back from step 1 with her.
