Like with Dany, Tyrion has some new winter wear here, but the bigger deal is that's he is back at Winterfell for the first time since the very first season. He stands on the ramparts, clearly in conversation, and likely with a mix of feelings. He's been through a hell of a lot since his first visit: back then he went as part of Robert Baratheon's entourage. Since then, he's killed his father and been estranged from his family. And if that's not enough, he's also seeing his wife, Sansa, for the first time since Season 4. They should have a lot to catch up on.
