Anons, help me out…

I only saw Season 1 of GoT, so I don't know if this works, but it might.

The FISAGATE movie poster followed by the next post sets up a series. The FISAGATE poster is obviously in the middle. The last poster is the "Sanctions are Coming" poster which is derived from the line "Winter is Coming" from GoT. I'm wondering if this relates to the "Follow the watch" post. I remember that there was a big wall in the north that had the Night's Watch on it, I think. Was this particularly associated with the "Winter is coming" theme? Because then "Follow the watch" might mean that something big is going to follow that last Q post.

If Q posts again shortly that likely doesn't work, but I figured I'd toss this out there.
