The STARZ hit television series, Outlanderis full of superstitions, but one thing is most certainly a fact: Claire fell through the stones in the 1940s and landed in Scotland 200 years prior. This delicate information is kept secret as the character attempts to navigate her way through a rebellious time period.

While most characters believe Claire to simply be a healer with witch-like tendencies, there are some characters that know the truth about the 20th-century sassenach. Here is a look at which characters from the STARZ television show know Claire Randall Fraser is from the future.

James Fraser

James Fraser is the very first person Claire informs of her time travel through the stones. This tell-all moment truly shows Claire's vulnerability toward the situation and the compassion and faith Jamie has for his new wife. He believes her wholeheartedly, even though he does not fully understand the magic, or how something of that nature is possible.

Murtagh Fitzgibbons

Murtagh found out that Claire was from the future while he accompanied Jamie and his wife to France in season two. After one-too-many half-truths and accurate foretellings, Murtagh became suspicious, so Jamie took him outside and explained everything to his godfather. Like Jamie, Murtagh believed Claire's fantastical tale after this.

Even though Jamie and Claire chose to keep the secret from Murtagh for quite a while, their relationship with Murtagh wasn't tested. In fact, being privy to this knowledge seemed to bring the trio together even more.

Roger MacKenzie

Raised by Rev. Wakefield, Roger was a mere lad when Claire went through the stones. As a man, he realizes the truth about Claire and even follows Brianna through the stones. The three are reunited in the 1770s and must keep the secret that each of them is from the future.

Brianna MacKenzie

Daughter of Jamie and Claire, Brianna is told of her father and even encourages her mother to reconnect with the red-headed Scot after Frank passes away.

Brianna also follows her mother through the stones later in the series, which shows that Brianna is also a time traveler.

Frank Randall

Frank Randall looks concerned on Outlander

As soon as Claire returned to her own time through the stones, she was reunited with her first husband, Frank. Though their marriage was testy and rather toxic, Frank was one of the privileged few that knew Claire's Craig Na Dun experiences. As a history professor, he even found an old newspaper detailing her obituary in the 1770s.

Tewaktenyonh

Tewaktenyonh was a Mohawk healer that met Claire when the Frasers began constructing the Frasers Ridge settlement and Jamie slew the "bear".

Her heartbreaking prophecy was proof that while Tewaktenyonh knew Claire to be from another time, this character was also gifted with a form of time-bending. Though Tewaktenyonh could not time travel, she seemed to accurately foresee the future.

Geillis Duncan

Like Claire, Geillis Duncan was also a time traveler. Geillis was constantly questioning and probing Claire for more information; it was as if she knew Claire didn't belong in that time period. During the witch trial portion of the series, Geillis finally understands that Claire is from the future. When she escapes death and is seen again in a later season, she confesses to Claire that she needs to have the 200-year-old baby (Claire's baby) as a blood sacrifice.

Mrs. Graham

Mrs. Graham is a character born and raised in the Scottish Highlands. She is very familiar with the magic of Craig Na Dun. She even prophesied Claire's time travel. Fast forward in the series, when Claire returns back her own time, she confides in Mrs. Graham. It is Mrs. Graham that convinces her to leave the past, well, in the past and try to make a life in Claire's new future.

She also passed this knowledge of Claire's abilities down to her granddaughter Fiona.

Rev. Wakefield

Rev. Wakefield shared Franks Randall's passion for history and was a very useful character throughout the first few seasons before the character passed away. The character found out that Claire could time travel in part because of Mrs. Graham's insisting and openness to the magic of the Scottish highlands, and in part because when Claire returned back through the stones, she returned to Rev. Wakefield's home to talk to Mrs. Graham.

Dr. Abernathy

Dr. Abernathy is one of Claire's best friends in her own time period. Equally overcoming adversity to become a doctor, the two were bound by their drive for success and breaking societal barriers.

Though he did not understand it, he accepted Claire's truth and remained a great friend and colleague to her.

Fiona Graham

Fiona Graham, the granddaughter of Mrs. Graham grew up in the 1960's Scottish Highlands which was still shrouded in supernational and superstitious beliefs. Learning for Mrs. Graham, Fiana knew Claire was a time traveler but did not make a big fuss about it. Perhaps in Fiona's eyes, this was just another tale come true.
