After the task, Jessie leapt onto Jack in celebration, suggesting a level of intimacy we hadn’t previously seen between the pair. This immediately sparked speculation that they might be brother and sister — especially given that Jack is reportedly engaged.
Adding fuel to the fire, Jack later said he “couldn’t be more proud” of Jessie, a surprisingly personal comment considering the pair supposedly only met when they entered the castle.
For many fans, it was yet another moment that felt like more than a coincidence.

Jack might need to rein in the physical affection, because fans are officially on high alert. One eagle-eyed viewer shared an Instagram video of Jack placing his hand on Stephen’s shoulder almost instinctively as the group huddled together — a small moment that sent the internet spiralling.
Some fans were immediately convinced the pair could be a couple. However, others were quick to shut that theory down after spotting Stephen’s alleged partner elsewhere, suggesting the interaction may point to a close friendship rather than romance.

Some viewers suspect that Harriet and Hugo are either siblings or at least know each other from their work as barristers. Others argue that the theory doesn’t hold, pointing to how Harriet orchestrated his vote-out — though anyone with siblings would know that doesn’t automatically rule it out.
Their debate also felt eerily familiar, as if they were slipping into patterns only people who know each other well would fall into.
Adding to the intrigue is the Latin quote hanging above the family tree in the castle:
“Beware whom you trust as your own blood. The sharpest knives are often handed to the table by faithful servants. Among intimate friends lurk the most secret enemies; take care not to let your confidence become the cause of your downfall and agitation.”

Many viewers are convinced they might be mother and son, pointing to a striking resemblance between the pair. Reece’s instinctive attempt to help Amanda during the skull challenge only added fuel to the speculation, leaving fans wondering just how deep their connection really runs.

We have a sneaking suspicion that Fiona might actually be Reece’s grandmother. Hear us out: he barely flinched when she didn’t save him during the challenge, and he didn’t complain in his confessional — or at least it wasn’t shared, possibly because he referenced their connection. Meanwhile, Fiona seemed unusually relaxed throughout the process, which could make sense if she’s quietly planning to protect her beloved grandson.

Two Northern Irish players, and no, they’re definitely not dating — Rachel is married with three kids, and Matthew is openly gay. But could they be siblings? They claim to hail from different parts of Northern Ireland, though we’ve seen contestants bend the truth about their backgrounds before.
After Claudia selected her Traitors, Rachel and Matthew shared relief that they were both Faithful — though we now know Rachel was bluffing.
What’s particularly intriguing is Matthew telling Rachel how pleased he was she wasn’t a Traitor. Innocent? Maybe. But coming from someone you’d only met an hour earlier, it felt… a little too personal.

These two are clearly close — friends, if not something more. Matthew lives in Edinburgh, while Stephen claims London as his base, though he’s Scottish through and through.
