Outlander enthusiasts have been combing through earlier seasons to quench their thirst during Droughtlander, searching for hidden gems in the acclaimed Starz series.

The second season saw Andrew Gower’s portrayal of Bonnie Prince Charlie regularly use the phrase “mark me,” leaving audiences puzzled over its meaning, reports the Irish Star.

Ronald D. Moore, the show’s executive producer, discussed the distinctive line on the Outlander podcast, stating: “This became one of the catchphrases for Charlie that he always says ‘mark me’, and then Andrew picked up on it and started adding it in.”

Moore elaborated, “So, mark me is a phrase of the time, it became one of Charlie’s catchphrases.”

First heard in a memorable debut scene within a brothel, Bonnie Prince Charlie’s signature “mark me” has since become ingrained in Outlander lore.

Intended as an attention-grabbing phrase with military origins, it quickly took root among the characters.

Andrew Gower himself has mused over the line, admitting: “It was a nice military, attention-seeking phrase but I didn’t expect the reaction that it had with fans and within the show.”

He found it amusing how quickly the catchphrase resurfaced in the show, commenting: “It’s a rather funny one and it’s very funny how one episode into the new season, you’ve already heard ‘mark me’ again.”

Speaking to Entertainment Weekly in 2017, he mentioned: “I think the writers were very keen to get it back in.”

In the series’ second chapter, the iconic term was employed by Bonnie Prince Charlie no fewer than 15 times.

The iconic ‘mark me’ phrase resurfaced in Outlander’s sixth season during Bonnie Prince Charlie’s dramatic escape to the Isle of Skye, aided by Flora MacDonald (portrayed by Shauna Macdonald).

Disguised as a woman, the Bonnie Prince evaded capture through the Scottish Highlands following the devastating defeat at the Battle of Culloden.

During a pivotal scene, he expressed his gratitude to Flora, declaring: “Mark me, dear Flora, your kindness will not go unremembered.”

The phrase “mark me” is prevalent in Diana Gabaldon’s Outlander series, despite historical accounts suggesting that the actual Bonnie Prince Charlie never used it.

Actor Andrew Gower reflected on his character’s desperate flight from Scotland and his discussions with Jamie Fraser actor Sam Heughan regarding the event.

Gower, talking about reprising his role, stated: “Working on Outlander, the cast, the crew and the fans, they hold such a special place in everybody’s heart, and especially mine.”

He concluded by sharing his appreciation for his time on the show: “And you know. I’m lucky to be able to bookend my journey of Bonnie Prince Charlie.”
