Q could have said JFK Jr was deceased, but all he said was "there is only Q".
I don't have an opinion about Q's identity, and I don't really care about R one way or the other - if R is a shill/LARP then yes, get lost!
But I do care and keep hope alive that JFK Jr, his wife and sister-in-law survived. Nothing wrong with hope! I think there is evidence that they live, and I think we've been seeing them here and there, around Trump, without realizing…
It is relevant to Q's mission of informing the US public of the evil activities of the cabal, the Deep State: if they are alive they are potential victims who got in HRC's way. This is connected to the presidency.
What do you want to bet that evidence exists of her attempt to kill JFK Jr to clear a political path for herself?
