In conclusion, out of all the information about the clues, only the one for "March 10th" related to Red can be considered somewhat plausible. And psychologically, Red seems a bit suspicious.
Look, "March 10th ---> State Coup + Cuban Revolution ---> Che Guevara ---> Che's Quote." Could something like that be possible?
But I don't want to suspect anyone and I won't. Most likely, I'm mistaken. So, as I said at the beginning of the day - nnv, just to be sure.
