David Berry is father to one-year-old Alexander, but the “Outlander” star has actually given his little lad a nickname inspired by his character, Lord John Grey, on the Starz drama.

“I remember when [my son] Alexander was born. I started calling him Little Lord Berry. He wears that name a little bit now,” Berry told Entertainment Weekly.

The baby boy was born in 2016 on the day Berry returned home to Australia after filming his scenes for “Outlander” Season 3 in Scotland. (The library scenes in episode 12 were filmed in Edinbugh, unlike the other Jamaica scenes, which were filmed in Cape Town.) Berry’s wife Kristina Tesic was already at the hospital in labor when his flight landed.

His mother-in-law may have been more forgiving than other in-laws, though. After all, she was the one who urged Berry to accept the role as Lord John Grey. She was apparently a longtime reader of Diana Gabaldon’s bestselling novels. “She was a massive fan of the book series before I had been cast,” Berry explained. “She was over the moon when I got it. So whenever I go meet her, she wants all the behind-the-scenes gossip.”

She isn’t the only fan whose opinion he worries about, though. Berry has definitely felt the love from “Outlander” fans. Lord John Grey is a fan favorite character, and right away, viewers let Berry know that they supported his casting. However, their enthusiasm adds a bit of extra pressure when filming.

“The fan base really drives the show, and meeting them has been truly life-changing because they’re so passionate and engaged in the show,” Berry told EW. “Always, in the back of your mind when performing these things, you think, ‘Are the fans going to like this?’ It’s an important part of the whole thing.”

Right now, the only thing that will make “Outlander” fans happy is Lord Grey rescuing Jamie (Sam Heughan). Season 3, episode 12 ended with Jamie getting arrested, but Claire (Caitriona Balfe) has to focus on finding Young Ian (John Bell) after finally getting a clue about where he is being held. As the governor of Jamaica, Lord Grey might be the only one who can save him.

The “Outlander” Season 3 finale airs Sunday, Dec. 10 at 8 p.m. EST on Starz.
