Honestly. The only chance she can redeem herself, is by sacrificing herself upon her final death. Nothing more value for her anymore. She's not a Bolvar 2.0.
No, no need to wrap it up but there is a need to come to a further conclusion than, "he's a puppet of death by the use of domination magic", he's not dead but currently, not of light, or alive either.
Because Domination magic is not the Jailer's invention? His tool, not his creation, it is a completely new school of magic added.
The Drust is not connected to Elune's realm, though. And the Night Warrior card is on hold while Ardenweald returns to its full glory.
I do not believe we'll kill the Sire in 9.2, his deal is done with Zovaal, and he's now free on his own again with his people. We'll most likely see a few Dreadlords but ever since the Sire got out, they've had no need to work for Zovaal anymore.
So, just Ethereal them, meaning, secondary content for them. Brokers, unlike Ethereals, are currently are 2 questionable cartels, and one questionable freelance.
You might not want to, but we see on forums that people would like glimpses of past dead characters such as Arthas and Rhonin, they already were able to push a majority aside by just stating they were soul crystals.
Is there a need to rush Shadowlands and leaving bigger questions? I know many whine and cry that they don't like it but doubt it'll stop before 2½ years, so we'll most likely see 9.2, and 9.2.5, and 9.3 being conclusion before a crossover patch. We most likely won't even hear about 10.0 in BlizzConline (Which they claim they might do).
