This post contains lots of spoilers from the series finale of “Outlander.” If ye havena watched yet, proceed accordingly.

The series finale of “Outlander,” which began streaming Friday, ends on a massive question: Did Claire and Jamie actually live after they seemed to die together on top of Kings Mountain? And while we don’t have a definitive answer for you on that front, we do have the answers to several other queries you might have regarding the time-travel drama’s final episode.

Callbacks to previous episodes! Nods to Diana Gabaldon’s books! Easter eggs for longtime fans! And that post-credits scene! We’ve gathered a bunch of deep “Outlander” intel in the list below. And lucky for us, we had series stars Caitríona Balfe and Sam Heughan, as well as showrunner Matthew B. Roberts, to fill in some of the details.

So once you’ve read our series finale recap, scroll down to see if you caught them all. And make sure to call out your own finale-related questions in the comments!

In his last will and testament, Jamie leaves everything to Claire except the following, which he divides up among his loved ones:

• Brianna receives 2,00 acres of land on Fraser’s Ridge
• All of the grandchildren receive £100 and Jamie’s books
• Jenny receives Ellen MacKenzie’s silver stag brooch
• Ian receives Jamie’s tools and weapons
• Marsali receives his quills, ink, and stationery
• William receives three casks of special whiskey and Jamie’s Bible

Both in bed with Claire near the top of the episode and also later with the bees, Jamie recites part of W.B. Yeats’ “The Lake Isle of Innisfree.” The work is name-checked in the books, though mainly as Brianna recalls Frank’s fondness for it, and a line from it was used as the title for the Season 4 episode, “The Deep Heart’s Core.” Here it is in its entirety:

“I will arise and go now, and go to Innisfree,
And a small cabin build there, of clay and wattles made;
Nine bean-rows will I have there, a hive for the honey-bee,
And live alone in the bee-loud glade.

And I shall have some peace there, for peace comes dropping slow,
Dropping from the veils of the morning to where the cricket sings;
There midnight’s all a glimmer, and noon a purple glow,
And evening full of the linnet’s wings.

I will arise and go now, for always night and day
I hear lake water lapping with low sounds by the shore;
While I stand on the roadway, or on the pavements grey,
I hear it in the deep heart’s core.”

This one’s a little more nebulous. Claire and Jamie have been deeply connected from early on in their relationship, and as recently as last season, when Jamie was allegedly lost at sea, she made that clear to Lord John. Caitríona Balfe tells TVLine that she saw Claire’s clutching at her chest in the finale, which coincides with the instant Ferguson shoots Jamie in the chest, as evocative of that conversation with Lord John.

“What I really loved was the moment that she feels it, she feels that hit,” Balfe says. And that was sort of a callback to Season 7, where he was supposed to have died. She was like, ‘But I don’t feel it, and I would. I would know.'”

The question longtime fans had held since the premiere — what was up with the man Frank sees watching Claire from outside the inn in Inverness? — was answered in the show’s finale: The man was, indeed, Jamie — or a spirit version of him — who disappeared when Frank approached. The finale went on to show us Jamie going to Craigh na Dun, an act that brought about the blossoming of forget-me-nots at the base of the standing stones. The desire to gather those flowers is what eventually brings Claire to touch the stone and get thrown back through time.

“Outlander” showrunner Matthew B. Roberts explains that the finale sequence is a combination of old and new footage. “The footage [showing] his back was from Episode 1, and we built a virtual model,” he says. “We didn’t go back to Falkland, where we filmed that initially, because… there was just no chance we were going to film this without it getting out. ‘Why would you be there, standing there, doing that with a rain machine?'” He laughs. “There was zero chance.”

Part was filmed on stage, part was filmed on location. “Everything looking at Jamie… is brand-new, and everything at the stones is brand new,” Roberts says. He recalls that the shoot at the stones was just him, Sam Heughan, and a small crew, and “it just was one of the most beautiful days I’ve ever seen in Scotland.”

In Season 4, a Cherokee woman named Adawehi recognized Claire’s healing abilities and prophesied that Dr. Fraser would come into her full powers when her hair was fully white. (Adawehi met a violent and sad end soon after.) Over the years, Jamie joked with Claire that her hair was slowly approaching that powerful state.

In the finale, after Claire seemingly joins Jamie in death, we see that her entire head is covered in white hair. Might that have something to do with what happens after…?

If you stuck around until the end of the finale’s credits, you were treated to a quick episode tag featuring Diana Gabaldon as herself, circa the 1991 release of “Outlander.” As a line of people wait for the author to sign her work, someone asks her about leather-bound journal near her on the table. She responds that it’s a “wee bit of inspiration,” and viewers recognize it as the place where Claire started writing her story (which happened to be the opening words of “Outlander” the book) earlier in Season 8.

The brief scene is a tribute to the behind-the-scenes staffers who were with the show for its entire run. The woman who asks Diana the question is script supervisor Margaret Graham. Sam Heughan’s driver, David Stewart; dialect/dialogue coach Carol Ann Crawford; and executive producers Maril Davis, Matthew B. Roberts, and Toni Graphia also are in the shot.

“Everybody in that room, it was our thank-you to them,” Roberts tells TVLine. “Basically saying: Hey, you guys stuck with us from Day 1. You put your hearts and souls into this show, and I wanted to do something to show, like, ‘Hey, we recognize you.’ And we wanted to say thank you to Diana for creating this world that has provided, ultimately, for so many of us.”

The set decoration also pays homage to the show’s long history. The book jackets feature the names of people associated with production, like composer Bear McCreary and set decorator Stuart Bryce, and the bookshelves are dotted with props from various episodes.

“We did that on purpose for the hunters and gatherers who want to go through that scene and see, ‘Oh, there’s this, and there’s that,'” he added. “I’m not gonna say wha tthey are, but there’s a whole bunch of props from throughout the season.”

Fun fact: Gabaldon, who is a consulting producer, has appeared in the series before, notably as a character named Iona McTavish in the Season 1 episode, “The Gathering.”
