Just a thought: could Ezra be the “another one” Yoda mentions in ESB (since it’s not Leia, who has never managed to learn the ways of the Force) ?
LUKE
Yoda spoke of another.BEN
The other he spoke of is your twin sister.
Originally when there were going to be 9-12 films the plan was to have Luke go off in search of his sister after ROTJ. But after ESB proved to be a huge hassle for George he decided to cut it short and just have the three films. But they’d already hinted at this other so they made Leia his sister to tie that up. The original intention was that if Luke failed Yoda could then try to recruit Luke’s mystery sister to finish the job.
As for Ezra, I think he has a very dark path ahead of him…
