Based on his relatively quiet screen time over the past couple of seasons, you would be forgiven for not remembering that Peter Dinklage is the top-billed actor on HBO's Game of Thrones.

For some time now, Dinklage's Tyrion Lannister has operated in a supporting capacity, at the heart of some touching scenes and occasionally ruling in times of his queen's absence, but otherwise a minimal presence compared to what some of his compatriots are getting into — like Jon Snow (Kit Harington) decimating House Bolton in "Battle of the Bastards," for instance, or Daenerys (Emilia Clarke) incinerating the masters of Slaver's Bay in the very same episode.

Expect the tide to shift for Tyrion as soon as the coming episode, "The Queen's Justice," for a couple of reasons. For one, viewers are finally about to lay eyes on Casterly Rock, the esteemed seat of House Lannister. In "Stormborn," Tyrion hatched a plan to send the Unsullied and Dothraki to his old stomping grounds, with an eye toward snatching his sweet sister's treasured home away from her. It doesn't look like Tyrion is along for the battle this week, because he's otherwise occupied at Dragonstone. Then again, with how swiftly characters are moving from one location to another this season, it's not completely unreasonable to guess Tyrion might make the journey to his childhood home after all.

Even if he doesn't leave Dragonstone, Tyrion has plenty of business exactly where he currently stands. The true must-see moment of the latest episode is Jon Snow and Daenerys Targaryen's first meeting. Fans have waited years, some for more than two decades, for the first official interaction between these two powerful figures. But Tyrion is an intriguing ingredient in the mix as well. After all, he's the one who vouched for Jon when Daenerys initially showed skepticism. What's more, Jon and Tyrion go back a long way. "All dwarves are bastards," and all of that. Both men have grown so much over the past six seasons and change. Their reunion isn't as hotly awaited as Jon and Dany's first meeting, but it's destined to be a riveting moment all the same.

Following "The Queen's Justice," only four episodes remain in season seven, and 10 episodes overall before Game of Thrones closes the book for good. (Until the successor shows, anyway, which won't involve any of the current series regulars.) That means we're swiftly running out of time to spend with Tyrion. Given his relatively low profile over the past two seasons, the short road ahead toward the finish line and his instrumental role in two of the coming episode's most pressing matters, expect this renegade lion from House Lannister to roar louder than he has in quite a long while.
