With the eighth and final season of Outlander upon us, fans of the Starz series have been trying to work out how Jamie Fraser’s (played by Sam Heughan ) ghost could have watched Claire (Caitriona Balfe) in the future.

Fans have theorised Jamie time travelled to pull Claire back to him, he died on the battlefield at Culloden or that he is dreaming.

Now, one fans thinks they’ve worked out a “beautiful” explanation and others agree it is a “lovely” theory.

Writing on Reddit, one fan shared: “In Book One – Jamie is seen watching Claire from outside the B&B in Inverness. He’s looking with longing and not just a little a bit of sadness. Frank confronts Claire about maybe cheating on him during the war. she wonders later if HE had done just that, within days she’s at the stones… Claire travels back to Jamie (obviously) – she hears the battle BEFORE she travels through the stones.”

They shared quotes from book one which detail how Claire could hear sounds of battle as she approached the stones at Craig Na Dun.

The fan continued: “In later books we know some of the Fraser family have the sight – Jenny at times talks about it openly. Jamie dreams about the kids when Bri and Roger are still in the future. He knows about electricity and telephones.

“STILL IN BOOK ONE – Claire, after the witch trial, tells Jamie the truth about who she is and where she comes from. He takes her to the stones and tells her to go back to Frank, to go back to where “she belongs” and leaves her, but remains nearby to keep her safe.

“We CAN assume that while Claire is thinking about going back to Frank she’s thinking about the last days they were together – she HAS to at least touch on the night Frank saw the highlander – even if SHE doesn’t make the connection herself, it’s a memorable night with the storm and the fight between them. Ultimately, she chooses to stay when she tries walking first to the stones, and then toward Jamie – and JUST KEEPS GOING.”

They recall how Jamie falls asleep at a nearby croft. The fan theorised that as Jamie slept, he dreamt of Claire and was able to call her back to him when she was in the future.

“what if…THAT’S ghost Jamie – dreaming of Future Claire – dreaming of the same night that Claire is thinking about AT THE STONES with the TIME WINDOW OPEN – when he can do more than dream…where his soul can exist in both places at once…and because HE WAS THERE. and BECAUSE he was there – he called Claire TO HIM because Frank saw him and confronts her. It’s a PERFECT loop. It’s a LOVE story not a GHOST story.”

Fans only have a few months left to wait to find out if the theory is correct but it would certainly be a lovely way to wrap up the mystery.
