Season 7, Episode 1 of Game of Thrones had plenty of plot twists and shocking moments to keep even the most casual viewer coming back for more. But after a few re-watches, even more layers of the story come to light. Here’s a spoiler-free look at all the references, callbacks, and Easter eggs you might have missed from “Dragonstone.”

This Has Happened Before and It Will Happen Again: First, I should point out that we’ve already covered a number of references and callbacks in our earlier coverage of “Dragonstone.” Jon and Benjen each giving their version of Ned Stark’s dad joke up there, among other things, was touched upon in the complete episode breakdown. The deeper textual meaning behind Ed Sheeran’s controversial cameo was covered here. And we broke down some of the book-based rules and ramifications of Arya slaughtering the Freys here. But since there’s more to cover, let’s dive in.

Some Close Reading: If Game of Thrones is going to put some ancient text in front of its audience, you know they’re going to pore over every word looking for some kind of clue. Most of the text in the book Sam is reading here has to do with either the Targaryen tendency to use dragonglass as decoration (which Sam says out loud) or the revelation that Dragonstone is built on a huge cache of the stuff (which we covered here). But some very sharp eyes caught a clue on the page opposite the Dragonstone map.
