Outlander's season finale is less than two weeks away, and "heartbreak" is the watchword.

Claire (Caitriona Balfe) and Jamie (Sam Heughan) seized upon the chance to change history as season 2 began, choosing to focus their energies on reversing the tide of the Jacobite Rising. Now, with the Battle of Culloden just hours away, their futures are more uncertain than ever.

"I haven't seen the last episode. Obviously I was in it somewhere, but I just remember it being very, very emotional and critical, actually," Heughan told Access Hollywood. "The time is getting so close to zero hour, to the point that they have to stop history from happening. Whether or not they do is the spoiler."

When "Dragonfly in Amber" hits screens on July 9, fans should brace for 90 minutes of gut-wrenching turmoil.

"It's so emotional...It's so heartbreaking," executive producer Maril Davis teased. "I don't cry any more at playbacks; I really don't because I've seen the stuff so many times. I cried like three times [watching the finale]. The music is wonderful, the writings amazing. I mean, Caitriona and Sam are heartbreaking. Get your tissues and your whiskey 'cause you're going to need it."

That doesn't mean episode 213 won't provide a little levity. According to writer Matthew B. Roberts, your emotions will run the gamete from surprise to red hot anger.
