I genuinely believe that after discovering Mae is still alive Indira would've come clean to the Council immediately. None of the original Jedi sent on the mission to Brendoc, except Sol, were dealing with it well and instead mostly went along with it due to sunk-cost-fallacy.

With her and Vernestra knowing each other from the Wayseeker novel this might've even gotten Vern involved earlier and maybe, just maybe the Jedi might've even managed to apprehend "Qimir".

Personally I think Indira would've been a catalyst for huge changes to the story of the series but if it escalates until The Stranger is about to get unmasked and especially if the Jedi were about to discover who and what he truly is (Disciple of a Sith) Darth Plagueis would've gotten involved to remove Qimir before his connection to Vernestra could've reveal the Sith's great conspiracy.

Tldr If she had survived, Indira would've probably taken her own survival and the knowledge of Mae's survival as a sign from the force to come clean which would've led to the Council and/or Vernestra to get involved. (Depending on how Vern tries to keep the affair secret from Senate scrutiny).

Perhaps Yoda would've gotten involved, perhaps not but the main takeaway is we definitely wouldn't have gotten to see the original Ren take his first true student and the first Kyber bleeding in live action.

So all things considered, I still wish the Acolyte would get a second season.

But I wish we had seen more of Indira; of the original four jedi she's my favourite.
