7 details you might have missed in the 'Outlander' season 7 premiere

In chapter 98 of "A Breath of Snow and Ashes," the sixth novel in the "Outlander" series by Diana Gabaldon, Jamie and Claire discuss the sacrifice that Tom Christie (Mark Lewis Jones) has made for them by taking the rap for Malva's (Jessica Reynolds) murder.

Jamie tells his wife: "Sassenach — I would have done the same, and counted my life well lost, if it saved ye. If he feels the same, then ye've done nay wrong to him, to take your life from his hand."

The scene, almost taken verbatim from the book, actually features at the end of the episode, so audiences see Jamie speak the line as well.

This introductory scene is a callback to the penultimate episode of "Outlander" season one when Jamie is captured by the Redcoats and likewise is shown standing with a noose around his neck at the gallows.

In that scene, Jamie was spared the hangman's noose by Black Jack Randall (Tobias Menzies), who had a far more sinister plan in mind for Jamie.

At this point, every "Outlander" fan knows the show's theme song, "The Syke Boat Song" by heart, but it's recommended you don't skip the opening sequence given that it gives audiences major clues as to what's to come each season.

This time around, many of the events from "A Breath of Snow and Ashes" and "An Echo in the Bone," that are expected to feature this season, are teased.

These include the fire that destroys the big house, Lord John Grey (David Berry) returning the sapphire Jamie once gave him, and Brianna (Sophie Skelton) and Roger's (Richard Rankin) journeying to Ocracoke by boat to pass through the stones and return to the 20th century.

The Irish-born singer's interpretation of "The Skye Boat Song" soundtracks the opening title sequence throughout season seven.

After O'Connor's new take on the song was announced in February, showrunner and executive producer Matthew B. Roberts said in a statement that "her rendition is, for me, a reminder of all that's beautiful about 'Outlander.'"

"Hers is a voice of the ages — one which pierces heart and soul — and embodies the spirit of the show."

In the season six finale, Claire sustained cuts to her cheek and hairline after Richard Brown (Chris Larkin) and his men arrested her with a plan to take her to Wilmington to be tried for murder. 

The fact that she's still sporting the same cuts and bruises in the season seven opener indicates that she wasn't languishing in jail for too long, and that the events of the episode take place soon after the season six finale.

We're sure everyone watching caught on to the fact that Roger was not quoting the Bible when he was asked to give the prisoners some fighting advice and responded: "Float like a butterfly, sting like a bee."

However, it's worth noting that it's a relatively modern reference that tells us a bit more about Wendigo Donner (Brennan Martin).

The world-famous boxer uttered those infamous words (which is followed by the oft-forgotten second line: "Your hands can't hit what your eyes can't see") in 1964 before one of his biggest fights, seven years before Roger and Brianna gave up their lives in the 20th century for the past.

This means that Wendigo must have traveled through the stones sometime after the mid-1960s.

When Tom confesses that it was he who killed Malva, he also dishes up some other family secrets too. He discloses that Malva was not his biological daughter, but his niece. As he tells Claire, his wife Mona seduced his brother, Edgar, then killed him when Tom was imprisoned at Ardsmiur around 1753.

This was something Claire actually cottoned on to shortly after the Christie family first arrived at Fraser's Ridge.

"Wouldn't Tom have still been at Ardsmiur when she was conceived?" she asked Jamie in season six, episode three, after learning that Malva was 18.

While she drops the subject, it's clear that the inconsistency weighed heavily on Claire's mind as she got to know the complex family and their strange dynamics.
