One of the most highly anticipated face-offs fans are hoping can be fit into the final two episodes of Game of Thrones is Cleganebowl, the fan-named fight between Sandor Clegane, a.k.a. the Hound, and Gregor Clegane, a.k.a. the Mountain. And based on the most recent episode, “The Last of the Starks,” we’re pretty certain it’s coming soon.

Last time we saw the two brothers together, they were reunited at King’s Landing after the Mountain was brought back from the dead by Qyburn. The Hound has hinted that the final fight between them is ahead. He tells the Mountain, “You know who's coming for you. You've always known."

During the latest episode, we see the Hound riding off to King’s Landing earlier than everyone else; he tells Arya Stark that he has unfinished business in the capital. Fans’ ears perked up at hearing that, knowing the unfinished business he speaks of is more than likely Cleganebowl. But since Arya is traveling with the Hound now, could she be involved in the fatal fight between brothers? TIME has theorized how Arya could be a major part of the showdown.

Two factors lead this theory: The fact that the Mountain is still on Arya’s kill list, and that season 8 has been so heavily focused on Arya's relationship with the Hound. TIME argues that the Hound might sacrifice himself to protect Arya from his brother, ending with the trained assassin killing the Mountain.

As we saw in episode 3, “The Long Night,” the Hound has even faced fire—the one thing he fears—to help save Arya. Though it’s true he wants to be the one to kill the Mountain, we believe he’d rather die than have Arya killed by his greatest enemy.

The latest episode also saw the Hound jokingly asking Arya if she was going to leave him for dead again, which TIME believes is foreshadowing just that. Because Arya was the one to kill the Night King, many people believe it’s unlikely she’ll also be the one to take down Cersei Lannister—the only other person still living on her list besides the Mountain.

We’re sure Arya has more kills in her this season, but traveling to King’s Landing alongside the Hound might mean she won’t be involved in the main fight for the Iron Throne between Daenerys and Cersei. She has already taken out the Night King and saved the Seven Kingdoms, so now she’s doing what’s best for her.
