Staring us right in the face!
Whenever Q says "10 days.", it means that whomever they are going after have 10 days to make a deal/comply. Once that is up, they forfeit their one and only chance to save themselves.
"10 days." doesn't mean we will see ANYTHING happen on our end. It is a message for THEM!
"Darkness." means it was their last chance, collectively. We are truly in the end game. Sides have been drawn and we are seeing it all play out now. We're just going through the motions.
It fits the time frame. I don't know what the sure deadline is for them to come forward, but the "NO DEALS!" leak today may be the confirmation.
Again, WE didn't need to know when the 10 days was happening. We just get to witness the aftermath.
