on the plus side, if "uhhh idk sith ruins underneath jedi temple" is canon now for trying to explain that plot hole, it means i have even more justification for declaring that my SWTOR sith character persists up to prequel era at least by being the reason that somewhere in the jedi temple there is a sign in comic sans in a breakroom somewhere reading:
"DO NOT TALK POLITICS WITH GHOST!!!!!!!!!!
(recipes ok)"
(force ghost of achates pachai, sith inquisitor voice) you've absolutely fucked up that cup of tea, by the way. don't pour boiling water straight over green tea leaves, you'll burn it horribly. no really, taste it, you see how bitter it is? exactly. you've absolutely messed it up. and you know what's also absolutely messed up is jedi philosophy -
"that was a long tea break, is the kettle on the fritz again?"
"no, just that sith ghost talking at me"
"ah. did he read you his manifesto again?"
"only partially. but it's fine, since i got a really good recipe for vegan buttercream frosting out of the deal"
