I've been pushing the view that a France State Dinner photo will figure in a meme in the finale. I won't repost my revised interpretation of finale since I think it is supposed to suck the fake news into a trap before we pounce, but you can find it above.
But I found two more drops that together suggest that the MOAB marked for the State Dinner should inspire memes. (Q responds to his own drop to emphasize.)
(The red carpet event is the 24 Apr 18 State Dinner for France.)
