Spoiler warning: This video recap contains plot details for “Outlander” Season 2, Episode 10, titled “Prestonpans.”

“Outlander” star Sam Heughan describes episode 210 as his “favorite episode of the whole season,” in part because of how “rewarding” it felt for him to be translating a historic Scottish battle like Prestonpans to the screen, and in part because of the performances of the entire ensemble as the Jacobites prepared to fight the British.

Heughan sat down with Variety to discuss his favorite scenes from “Prestonpans” and the surprising way they filmed that atmospheric battle scene. (Hint: It involved a gigantic tent.)
