6 details you might have missed in the 'Outlander' season 7 midseason finale

While most episodic titles this season have been taken from quotes in the "Outlander" book series by Diana Gabaldon, episode eight's title references the fact that almost every major character has a "shift in their journeys" in this episode, according to executive producer Maril Davis.

She told Insider that there are "a lot of obvious kind of reasons why this title came about."

"Jamie and Claire, obviously, originally at the beginning of this season intended to go to Scotland, then they got waylaid, and now they're back on that path," she said. "Ian, we're leaving him on a bit of a weird cliffhanger with Rachel and he's leaving his dog behind."

"Certainly for William, he'd had such an idealized, boyish vision of how war is supposed to go and what being a soldier is all about. It's a turning point in his life in terms of realizing the realities of what war is like and what it means to fight."

While Davis didn't mention Brianna (Sophie Skelton) and Roger (Richard Rankin), it's clear the title refers to them as well, given the unexpected turn their lives take by the end of the episode.

Claire's (Caitríona Balfe) reputation as a healer precedes her in the rebel camp and she is paid a visit in this episode by a general (Rod Hallett) who is after a particular healing herb that might help one of his soldiers.

After making a trade for some laudanum, since she used the last of her supplies on healing Jamie's hand, Claire asks the general's name and is left speechless when he tells her he is Major General Benedict Arnold, the man who mounted the revolutionary army's infamous betrayal.

Per Smithsonian magazine, he served the cause of the American Revolution until 1779, when he grew disillusioned and shifted his allegiance to the British.

As Claire tells Jamie, Arnold's name becomes "synonymous with being a traitor" to future generations and they shouldn't try and stop him, as it could interfere with the revolutionaries taking the victory.

Arnold joins the growing list of prominent historical figures from the American Revolutionary War who Jamie and Claire have crossed paths with this season, including Colonel Daniel Morgan (Barry O'Connor), Cornelius Harnett (James Weber Brown), Major Donald McDonald (Robin Laing), and Governor Josiah Martin (Eugene O'Hare).

During Jamie (Sam Heughan) and Claire's conversation with General Arnold, Jamie accidentally finds himself quoting a line of poetry that Claire has taught him.

When asked about his take on the philosophy of endeavor, and whether men should know their limits or deny them, he responds: "Well, I've often heard it said that a man's reach must exceed his grasp, or what's heaven for?"

Arnold delights in the "perfectly expressed sentiment" and asks where Jamie heard it from, to which he and Claire tell him it's from a poet, whose name they can't seem to recall.

The poet is in fact Robert Browning, an English writer who will not be born until 1812 — over three decades later.

The poem itself is "Andrea del Sarto," which is a meditation on the Renaissance painter of the same name, and is rather long at 267 lines, so it's impressive that Claire and Jamie are able to recall a line from it.

The scene in which Colonel Morgan gathers a crowd and delivers a fervent speech about the evils of the British Army, before ripping off his shirt to expose the gnarly scars from a flogging by a redcoat, is a powerful callback to the first season of the show.

Back then, when Dougal (Graham McTavish) was trying to gain sympathy and support for the Jacobite cause, he used the brutal flogging scars on Jamie's back, administered in a fit of rage British solider Jonathan "Black Jack" Randall (Tobias Menzies), to prove to people that the British should not be trusted.

The only difference this time around is that Morgan is a willing participant in the ploy, both delivering the speech and showing off his own scars. As he says, he was sentenced to 500 lashes, but the British soldier only gave him 499.

This is something that actually happened to the Welsh-born colonel. In 1756, he was punished with 500 lashes, typically considered a fatal number, after he irritated a British lieutenant at Fort Duquesne. He carried the scars, disdain, and story about the miscounted number of lashes for the rest of his life.

The song is titled "Tha Mi Sgìth 'n Fhògar Seo," which translates to English as "I am weary of this exile," a fitting song for Jamie and Claire's return to Scotland after more than a decade away.

According to the blog The People's Voice, the song was composed by John MacRae (also known as Iain mac Mhurchaidh), a Scot who also emigrated to North Carolina and got caught up in the American Revolutionary War.

MacRae fought as a Loyalist soldier during the American Revolution and was held as a prisoner of war in Philadelphia, where he is said to have composed the song, expressing his regret for having ever left his home in Scotland.

After the final shot of Claire and Jamie welling up as they set their eyes on Scotland's lush and rolling green hills for the first time in years, the screen fades to black, and an in-memoriam message appears before the credits.

"In memory of Sinéad O'Connor," it reads.

The Irish-born singer passed away in July at the age of 56. Lending her voice to the "Outlander" theme song marked her final musical recording.

When it was announced in February that her interpretation of "The Skye Boat Song" would soundtrack the opening title sequence for season seven, 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."
