6 details you might have missed in the latest episode of 'Outlander'

There was no pre-credits scene in "Outlander" season seven, episode five, most likely to make audiences take note of the new, updated opening credits.

While Sinead O'Connor's rendition of "The Skye Boat Song" remains unchanged, some clips have been swapped out in light of the fact that the story now features two simultaneous timelines: the Frasers' life in the 18th century and the MacKenzies' life in the 20th century.

For instance, the shot of Brianna (Sophie Skelton) and Roger (Richard Rankin) rowing to Ocracoke has been replaced with a clip of a pair of hands holding a colorful airplane toy in the more modern timeline.

At another point, Brianna and Roger's red 1980s car driving up the road to Lallybroch is seen where previously the credits included the clip of water being gathered from a trough to help combat the fire at Fraser's Ridge.

Other new moments in the opening credits include Brianna in her work uniform looking over Loch Errenty, and her and Roger swaying slowly at dusk as they embrace outside Lallybroch and their temporary caravan home.

Eagle-eyed fans might have also spotted that certain names, such as Mark Lewis Jones, no longer appear in the opening credits — indicating that we won't be seeing his character, Tom Christie, again.

In its place, the name Charles Vandervaart appears, which is unsurprising given the large role William Ransom has in the remainder of season seven.

While several episodes this season so far have been named after quotes in the "Outlander" book series by Diana Gabaldon, season seven, episode five's title "Singapore" references a battle that takes place 165 years after the one Claire and Jamie find themselves involved in at Fort Ticonderoga.

Discussing General Fermoy's (Olivier Raynal) ill-conceived plan to defend the fort, Jamie (Sam Heughan) tells his wife: "He's convinced an attack will come by land and not from across the water."

Claire (Caitríona Balfe) responds: "It reminds me of the Battle of Singapore, though the other way around."

She then explains how in 1942, the British Army erroneously considered the jungle terrain surrounding their military base in the southeast Asian country to be impassable — until the Japanese Army proved it wasn't.

While Claire's words inspire Jamie to demonstrate to Fermoy that scaling the steep and rocky hills that sit across the water from their own encampment is feasible, their prescient warning ultimately falls on deaf ears.

By the end of the episode, the fort is taken by the British, just as Singapore was taken by the Japanese.

After Ian (John Bell) is dispatched to deliver a letter to someone in the Mohawk community where he used to live, he is not exactly surprised when he runs into his former wife Emily/Wahionhaweh (Morgan Holmstrom). He is surprised, though, when he meets the son she supposedly shares with her new husband, Swiftest of Lizards.

With red hair just like his own and mixed ethnicity, it's clear as day that he is in fact Ian's son.

Emily asks Ian to give their child an Anglicised name for the future, in case he decides to leave the tribe in the future. More than happy to oblige, Ian gives him the moniker Ian James, after himself.

The moment echoes Jamie's christening of his own secret son in season three, episode four of the drama.

Unlike Ian and Swiftest of Lizards, William Ransom (Charles Vandervaart) wasn't aware that Jamie was his father at the time, but happily accepted the name that Jamie christened him with during the impromptu Catholic baptism before Jamie left Helwater.

In both cases, it inexorably ties father and son together — even if their familial relation cannot be publicly acknowledged.

While significantly faded to mark the passing of over 200 years, the once-colorful tapestry that hangs on the wall in the family's dining room at Lallybroch in the 1980s could well be the one that hung in the castle in the 18th century.

The couple also appear to have other heirlooms from the property. In the scene following the MacKenzies' family dinner, Roger takes Briana to his study where he reveals to her that he has found a hidden drawer in the old laird desk from the property.

When Brianna gets locked inside one of the tunnels running through Loch Errenty as a prank on her first day on the job, she doesn't let it faze her too much as she has the tunnel's structure memorized.

However, she is slightly taken aback when she finds her pathway blocked by what looks like a shimmering, translucent barrier and begins to hear the familiar buzzing noise that she has previously heard when passing through standing stone circles to travel to and from the past.

As she approaches it, the noise gets louder and louder until she can't stand it any longer. Seeing no other option but to pass through it, she takes a run at it. Emerging on the other side unscathed — and still in the 1980s — she's perplexed.

So has she stumbled across a new place where time travel is possible? If she had a gem on her, would she have been flung back in time?

In the season two finale, "Dragonfly in Amber," the series flashed forward for the first time and showed Claire in 1968, twenty years after she left Jamie and traveled back through the stones to her own time period for the safety of their then-unborn daughter.

Audiences learned then that she had raised Brianna far away from Scotland, and on a rare visit back, she comes across a stone laid in remembrance of Clan Fraser at Culloden. Believing that Jamie had died in the battle, she uses the unofficial grave marker to speak with Jamie, telling him all about their daughter and her life since they parted.

In season seven, episode five, there's a neat parallel as we see Brianna do something similar, with the makeshift cairn that Jemmy (Blake Johnston Miller) has made in the family graveyard at Lallybroch.

In both instances, neither Claire nor Brianna are at Jamie's official final resting place (which remains unknown). But it's the closest thing they have to the real deal. Like her mother before her, Brianna takes the opportunity to catch Jamie up with everything that's been going on in her life since she left him.
