So far in Season 7 of Game of Thrones there’ve been *lot* of callbacks to characters and events from the first few seasons of the series, but it seems the latest might just be the downfall for this major player. Spoilers ahead for every episode so far of Game of Thrones.

For seven seasons, Petyr “Littlefinger” Baelish — an unimportant Lord from a lower house — has been outmaneuvering our favorite characters and conning his way to the top. From his betrayal of Ned Stark and his role in Joffrey’s death, to the reveal that he masterminded Jon Arryn’s murder, Littlefinger has always been one step ahead, until now.

In the preview for Episode 4, “The Spoils of War,” Littlefinger is seen brandishing a dagger — the very dagger that was used in the Bran Stark assassination plot. Could the return of this dagger mean the end for Littlefinger?

Back in Season 1, after the attempt on Bran’s life, Catelyn Stark went on a witch hunt for the person behind the plot using the only piece of evidence she had: the Valyrian dagger. Littlefinger — her childhood friend and longtime admirer — claimed to have lost the dagger to Tyrion Lannister while gambling. Now, Littlefinger has never fessed up to the crime (poor Catelyn died having never learned who was behind the plot), and the storyline faded into the background. But that doesn’t mean it won’t come roaring back with a vengeance.

Not only has Season 7 brought Bran back to Winterfell and seen him reunited with Sansa, he’s returned as the Three Eyed Raven, meaning he knows EVERYTHING.

Littlefinger is not a popular guy at Winterfell — the only thing keeping him welcome are his bannermen from the Vale — and right now, Sansa and Jon aren’t aware of the many, many crimes he’s committed. If Bran knows the truth about Jon’s parentage and Sansa’s marriage, we’re *pretty* sure he’s aware that Littlefinger doublecrossed Ned (causing his death), potentially tried to have him killed, and a whole host of other immoral acts.

If and when the Stark kids find out what he did to their family, he’ll be dead before Arya can say “valar morghulis.”

We think the dagger’s reappearance — it hasn’t been seen since Season 4 — signals Littlefinger’s getting a little bit nervous about his safety at Winterfell. And since we already know that dagger ends up with Arya, we have reason to believe that the dagger itself might bring the end of Littlefinger.

We’ll find out if Littlefinger’s days are *actually* numbered or if he’s lucky enough to survive the rest of the season on Sunday.
