Emmerdale fans believe they have rumbled who Chloe really is, after a chilling clue that could mean Sarah Sugden is in serious danger.
Sarah was desperate to meet the family of her tragic donor, who sadly died in a car accident three years ago.
Chloe did meet with Sarah and the pair got emotional, but the meeting was cut short when Sarah decided against it.
She has seen her a couple of times since though, and they have bonded over Gemma and what she was like.
In the latest episode of the ITV soap, Chloe opened up about her parents' grief and the fact she isn't allowed to even talk about her late sister.
Chloe broke down as she repeated how much she missed Gemma, but felt as though her family were just ignoring her.
It's then that she was asked by Sarah's uncle Noah whether Gemma had had a boyfriend, to which she revealed Gemma liked girls.
Sarah seemed surprised by this, while Chloe said that her sister's sexuality left Gemma struggling and falling out with her best friend.
Gemma apparently liked her unnamed best pal a lot and wanted them to be more than friends, but she didn't feel the same way and they fell out just before she died.
Chloe admitted that Gemma wasn't sure she should have opened up after this, but Noah pointed out that she must have thought a lot of her sister to choose her to be the one she confided in.
But viewers were not sure about the story and believed Chloe might have been "lying through her teeth", because she kept avoiding certain questions about her apparent sister and their family.
Chloe's behaviour and the fact she was acting weirdly around Sarah, left many wondering if she was even Gemma's sister after all.
Some fans believe that perhaps she might have been Gemma's girlfriend, or even the best friend she fell out with - or there's the chance she liked Gemma, but Gemma didn't fancy her back.
Either way, fans are convinced Chloe is lying about her relationship with Gemma, and they think that she may be obsessed with Sarah.
Taking to Twitter, one viewer wrote: "Taking a punt Chloe isn’t Gemma’s sister, but ‘the friend’ she just mentioned."
Another agreed: "Don't believe chloe she doesn't answer questions about certain things. And sounds like makes stuff up on spot. She's deffo suss."
A third tweeted: "Chloe isn’t Gemma’s sister, she was her girlfriend. She’s lying through her teeth."
Meanwhile, another wrote: "Chloe is Gemmas girlfriend? Becomes obsessed with Sarah? Are we going there @emmerdale two psychos at same time! Come on!"
Emmerdale airs weeknights at 7pm on ITV, with an extra episode at 8pm on Thursdays.
