I've been digging into RBG - and it's interesting - I think she's either dead or comatose and this might be why - if she has Alzheimer's as some have suggested - she may have been getting cult cures - but now have been cut off from that supply starting 09/2018 due to the full time security detail.
Also interesting regarding RBG this Comey tweet the "amazing cast" part of it in particular makes me think he's calling on plants as that amazing cast to "rise up" and play the music loudly (the way the cult views their shenanigans in the media is often likened to music)
but looking deeper - "vital message" is a book by sir Arthur Conan Doyle "Are the dead really dead?"
Supreme Court is the entire Judicial branch in a literal sense as they have final say - Q said it's essential (along with senate but not house) - I think her losing her vote means the military tribunals can no longer be challenged legally. They need her to avoid jail - and so perhaps Comey is calling for some kind of effort around her.
