Laoghaire (played by Nell Hudson) was last seen trying to shoot her ex-husband Jamie Fraser (Sam Heughan) in season four of Outlander.
Furious with him for going back to Claire Fraser (Caitriona Balfe) upon her return, Laoghaire couldn’t temper her anger and she showed up at Lallybroch with a pistol.
Eventually the characters managed to put aside their anger and Jamie agreed to pay off Laoghaire, but their lives will forever be intertwined.
When Jamie and Claire travelled to the Americas, Laoghaire’s daughter Marsali (Lauren Lyle) stowed away with them, and quickly fell in love with Fergus too.
Brianna Randall Fraser (Sophie Skelton) was faced with a terrible dilemma when she then ran into Laoghaire in the Highlands after travelling through the Standing Stones, completely unaware who the kind and welcoming woman taking care of her was.
But what if Laoghaire decides it’s time to chase her daughter and meet her first grandchild on the other side of the Atlantic in season five?
It wouldn’t be too much of a stretch to believe the mother-of-two would be aching for a reunion with her daughter.
And coming face to face with Jamie and Claire once more would undoubtedly produce fireworks.
Jamie continues to pay Laoghaire alimony, so regardless the character remains in the Frasers’ lives in some capacity.
Another theory about the Outlander world could suggest that the entire reason why Claire and Jamie were separated even longer over the painful 20-year period they were in different times was because of Frank Randall (Tobias Menzies).
Frank secretly learned Jamie was actually alive and had survived the Battle of Culloden, but chose not to tell Claire.
And the latest speculation muses the reason he didn’t come clean was actually because he didn’t believe his wife had actually travelled back in time.
A confused fan called onlyonecandikuka took to Reddit to discuss the issue.
“It has been really bothering me the relationship that Frank and Claire created in season three,” they said.
“I get that Frank thought that divorcing Claire would take Bree away from him, but it was stupid for them to stay married. Especially when they were having an open marriage anyway.
“But then when we find out Frank knew that Claire would end up going back to Jamie, and he didn’t even tell her that Jamie was alive?! He could have told her, and he could have moved on with his life as much as she moved on with hers.
“I hate that Jamie and Claire were denied 20 years together, and I can’t stop obsessing over what could have been!
Little Nest of Vipers then said: “Meh…Claire would have been absolutely miserable knowing Jamie was alive, but she wasn’t going to leave her child during that time and no way was she taking her through the stones. I can see both sides, really.
“Frank low key thinks she’s nuts, but leaves some clues just in case she wasn’t. I never got the impression that he was 100 per cent sold on the time travel even though she was able to provide some proof.
“I was a little salty about the 20 year gap too, but after reading some of the later books that include children that require care…well, I ended up appreciating the skip in childcare/pining for Jamie,” they added.
Another user called derawin07 backed up the theory, saying: “Frank definitely does not believe in time travel 100 per cent.”
Outlander season five returns to STARZ and Amazon Prime Video in 2020.
