A favorite "Game of Thrones" ship is even more intense than it looks.

Season 7 really got us on board with the idea of Tormund, Brienne, and their monster babies, thanks to brilliant performances by Kristofer Hivju and Gwendoline Christie as the lovesick wildling and his reluctant object of affection. They took a simple line from the script in Season 6 and managed to turn it into an unexpected TV love for the ages. But it doesn't end between takes. Christie revealed during a Sept. 5 appearance on "Late Night with Seth Meyers" that Hivju continues using his potent stare on her even after the cameras stop rolling.

"He likes to continue being in character even off set," Christie told Meyers of her co-star.

She described his behavior as "terrifying," and pulled out a hilarious anecdote as proof. It seems even the simplest of activities, like eating a sandwich, can become seductive moves when Hivju does them.

"He will start, you know, chewing a sandwich wildly at me. ... Really kind of making love to that sandwich as he eyeballs me," she said. "So strong. Eyes like lasers boring right in."

Those laser eyes present a unique challenge, because it is hard for her not to laugh. The classically trained actress admits it is "possibly the one time" that she can't help but "dissolve." The problem, she revealed, is that she wasn't prepared for Hivju's lustful gaze, least of all its intensity.

"No one told me that this was going to happen," she said of the improvised look that kicked off their budding romance. "I was not expecting the power, the magnitude of ... intense sexual intention to pour out of a man's eyes and cover me."

We just hope we'll get to see more of it in Season 8.

Watch Christie's hysterical descriptions below.

"Late Night with Seth Meyer" airs weeknights at 12:35 a.m. ET/PT on NBC.
