Well, TLJ also already broke that rule first with the Rashomon flashbacks, so I don’t see why we have to preserve that rule now. Also, I think the training flashback is more relevant where it is, and it also might affect the pacing in a weird way to add the flashback there. If anything, I wonder if we could add the flashback sound effect from TLJ to when we transition into the flashback.

If we wanted to establish Leia’s Jedi training earlier, maybe it could fit somewhere into Rey’s forceback in TFA?
