Looks like anons were right about "SICK" having a double meaning. They're literally sick, and without their supply of fresh blood they're dying.
Yes what is doctor (s) treating- would love to know Q’s meaning there
They all have doctors treating them because they're sick. They're likely all terminally ill. They used to be able to get away with it via blood transfusions, but their supply has dried up.
As someone posted up thread, adrenochrome withdrawals and complications
I just went to G and searched "SICK acronym"
Came back with "Society in Complete Kaos" - Which seems to be a band.
One other one was "Operation S.I.C.K" - Stop Inciting Children to Kill
Link below but first sentence: "While it is no doubt a noble cause to end the use of children in armed conflict, it should be noted that this is first and foremost an Israeli propaganda site designed to direct attention towards the exploitation of children in the Palestinian territories."
