The Game of Thrones season 7 finale aired on Sunday, much to the despair of fans who face a long wait for the final eighth season in 2018, or possibly even 2019. That's a long time, people.
And to make the wait even worse, Game of Thrones has released the message that Jon Snow sent to Sansa in the finale. The night is dark and full of spoilers, so continue with caution.
So as the younger Stark siblings were teaming up to take down Littlefinger, Jon Snow, or as we now know him, Aegon Targaryen, sent a letter detailing his success at the negotiation table with Daenerys and Cersei. Bran can be seen clutching the letter when he reunites with Sam, but never said what was in it.
