Outlander’s Frank Randall (played by Tobias Menzies) might have had a difficult relationship with his wife Claire Fraser (Caitríona Balfe), after she returned from the past pregnant with the child of a 18th century Highlander whom she’d fallen in love.

However, the Oxford historian’s devotion to his daughter Brianna MacKenzie (Sophie Skelton) was undeniable, reports the Express.

Although Frank struggled with Claire’s fantastical tale about time travel and Jamie Fraser (Sam Heughan), he did seem to secretly believe the strange story and even looked up the Scot in the history books.

Moreover, it seems he had an inkling that Claire and also Brianna would venture into the past one day to be with Jamie.

To this end, it appears Frank prepared his daughter from an early age for the possibility that Brianna would go to find her biological father.

Many took to Reddit to speculate about what Frank really knew about Jamie, time travel and how he equipped Bree with the skills needed if she went through the stones.

One person posted on the forum: “He knew Claire and probably Bree would go back when Bree was young, because he started “training” from her from an early age.

“I’m sure she mentioned when she started horseback riding, handling a knife or gun, or fishing (one of the skills) and a rough age but I can’t recall the book or the scene.”

The user continued: “He had a great interest in Jamie, Fraser’s Ridge, and the revolution early enough to have researched, written, edited, and published a book before he died.”

They added: “I still believe Frank’s background in military intelligence played a role in his research.”

A second echoed these sentiments: “Yes, it definitely feels like he knew A LOT more than we know right now because of his background in the military intelligence, maybe even about time travellers.

“Maybe he believed Claire’s story because of her 18th century outfit or he knew more before then because of his connections with Roger’s father for example.

“My question is, could’ve he known other time travellers too (and also about their abilities) or could’ve he had someone on the “inside” (like someone who could travel in the same time period as Claire and Bree)?”

While a third person said: “I also feel like a complete moron 20 years into this not realizing or thinking about Frank at all actively training Bree to be in the past though it is all so obvious now after reading here [sic].”

A third wrote: “Frank knew Claire would return to past while Bree was still a little girl.

“I believe he corresponded with the Reverend frequently, and the Reverend kept tabs.

“I believe he knew Jaime was alive the whole time, and didn’t tell her out of fear he could be the catalyst that would set events in motion of Claire going back and taking Brianna. One thing we know for sure, he knew they BOTH went back.”

So, it appears Frank was well aware his daughter would eventually go through time and tried to help her do this.

The things Frank taught Brianna showed how capable she was compared to her husband Roger MacKenzie (Richard Rankin), who struggled with his lack of practical skills in the past.

For Roger, the past was a steep learning curve for the historian, who had some very unfortunate and brutal moments, including unwittingly getting attack by Jamie who thought he was Brianna’s rapist.

Additionally, Roger was accidentally hanged but managed to survive with the whole ordeal proving to be highly traumatic.

Eventually, Roger managed to find his place in the church in the past as he became more grounded with his family.
