Hey no worries, take all the time you need! RL stuff always comes first! :D Good luck with the new certification though, hopefully this one works out better for you! :3
-If I'm remembering rightly, we said something about Revan and co camping out on a nearby moon or something? XD sooo potentially they could be holding Meetra on Odessa, or if we wanna chuck them literally into the frying pan we could say Arcann wanted to keep a real close eye on her, in case Revan came after her, so was holding her on Ziost? (then there's more chance of stuff going wrong, plus they might have the Knights to back them up? XD) but up to you, whichever you feel fits I can roll with it :)
-I think we may have decided to kill her off, too. Either way, nobody's died for a while (since Voldon) so might be a good time to throw another one in - plus, will give Kytra and Ethan a real taste of "this is what it means to be a Champion, sometimes it sucks but you've gotta deal or you're gonna get chewed up and spat back out" ;)
-I shall start spitballing Revan's master plan in the meantime, because yes, I'm sure he would have one :P
-As for Vitiate...that could be very interesting? I don't imagine he's the type to sit on the sidelines and spectate when there's death and destruction going on XD How involved we make him, though, is something to think through? The "established" lore seems to suggest he and Revan have some sort of beef going on, hence why Revan went storming off into the unknown regions to hunt him down (and drove himself kinda crazy in SoR trying to bring him back just so he could kill him himself... seriously, Revan, why?! everything was fine till you did that, dude XD) so it could be potentially interesting to build into some kind of final showdown (ala-Bracknell-style maybe? hehe) between Vitiate, Arcann, Vaylin and Revan and the Champions?
I can't think of anything else but that should cover the main bits for now? XD We can always iron out the finer details of the later points as they approach that time in-posts :3
