“Outlander” has officially cast their Lord John Grey. Australian actor David Berry will play the role in Season 3 of Starz’s time travel drama.

The role is minor but pivotal in “Voyager,” the Diana Gabaldon book on which Season 3 is based. Grey is a former soldier who is now a governor in Ardsmuir Prison. He’ll befriend Jamie (Sam Heughan), who is a prisoner.

Entertainment Weekly, who first reported the casting news, also released the official description for Grey. He’s described as a gentleman with a strong loyalty to his family and morals. He isn’t perfect, though. “A scandal from his past has relegated Lord John to an undesirable position as governor of a desolate prison in Northern Scotland,” the description reveals.

Grey was actually already introduced in Season 2 as a 16-year-old (played by Oscar Kennedy), but the series jumped ahead 20 years in July’s season finale. Clearly, he’s gotten into some trouble since then to end up working at a prison. Book readers know that Grey is a closeted gay man, and he’ll be disappointed after falling for Jamie.

Heughan, who started filming last week, already extended a hello message to his new co-star on Twitter (though David Berry doesn’t seem to have an official account on the social media network yet).

The character is a fan favorite and even earned his own series of stories from Gabaldon. “Outlander” viewers, of course, are often very opinionated about the casting decisions. Find out what they’re saying about the Berry in the role below:

It’s a good thing that audiences are taking a liking to him. If successful, Berry could potentially star in his own spinoff series one day. Gabaldon wrote eight stories for the character in the form of books and novellas, so there is certainly enough material. However, no plans have been made yet.

“Oddly enough, we always joke about spinoffs, whether it’s Lord John or Black Jack [Tobias Menzies] or this person or that person, because there is just so much material,” showrunner Ronald D. Moore told the Hollywood Reporter in June. “[Author] Diana [Gabaldon] gives us so much in the books that you can probably make 10 series and the fans would watch it all. We haven’t really discussed it seriously if we could do that, but that would be something for Starz to order before we could start talking about it seriously.”

“Outlander” Season 3 is rumored to debut earlier in the year than last season, but no premiere date has been confirmed yet.
