I’m assuming you will be removing the Yoda cameo? I’d be wary of removing the Plagueis cameo, because at least that explains how Quimir and Osha are screwed.
And the link between Vernestra and Q’mir doesn’t make sense now in a standalone story… it was setting up season 2…
Their link does go at least a little ways in explaining why Vernestra would want to cover up the whole thing. It’s her own failure that she doesn’t want to confront. But I do agree that it was sequel bait. Perhaps you could just tweak the scene between Mae and her concerning going after him? So it’s more of thing she wants absolutely nothing to do with going forward?
I suppose her cover up could work as a way to preserve the entire Jedi Order’s reputation, still.
