Dark Euphoria theory emerges about Bishop following ‘giveaway’ details in last episode

Warning: This article contains spoilers for Euphoria season three

We've now had four episodes of Euphoria season three - and the fan theories are well and truly flowing.

Starring huge names like Zendaya, Jacob Elordi, Sydney Sweeney, and Hunter Schafer, the drama-filled HBO TV show returned to screens last month, with new instalments dropping weekly.

As well as returning cast members, fans have also been treated to some new faces - notably ruthless strip club owner and Rue's (Zendaya) new boss Alamo (Adewale Akinnuoye-Agbaje) and his quiet but calculated henchman Bishop (Darrell Britt-Gibson).

The last nail-biting episode saw Rue be questioned by the DEA (Drug Enforcement Administration) after she was pulled over while picking up drugs for Alamo's club from her ex-boss Laurie with Bishop.

She's offered a risky deal of avoiding prison if she can become an undercover informant for the police, landing her in a very sticky situation.

However, this has sparked a fan theory that Rue is potentially not the only one who's a mole, thanks to a few dodgy looks Bishop gave her when they were playing cards, and she was trying to question Alamo while her phone was bugged, without being obvious.

Viewers also find it suspicious that Bishop did the drug pickup with Rue, so he could have known her whereabouts to tip off the police and get her on board, too.

One convinced X user wrote: "Bishop is definitely undercover… the looks he’s giving Rue. Either he knows or like Rue is just terrible at lying but both can be true!"

While a second added, "I'm watching Euphoria, and I feel like bishop is definitely looking out for Rue in a way.. prolly even a undercover."

A third and fourth chimed in with: "Bishop is absolutely undercover too by the way #euphoria" and "Idk I feel like Bishop is fishy as f*** #Euphoria."

And a fourth wrote: "Bishop is 100% a fed. Those Rue stares are screaming, 'I see you, liar'. Euphoria plot twist incoming."

Meanwhile, another fan responded: "I agree, but I wonder why the cops haven't busted Alamo or Lori yet if Bishop was bugged & undercover. If the whole point was catching a transaction?"

"I don’t know if the DEA just pops up randomly on people but it seems like Rue was set up. And since we know it wouldn’t have been Laurie and her crew that leaves Bishop who knew exactly what time she was leaving and the car she was driving #euphoria," reasoned someone else.

While another viewer agreed: "Guys what if Bishop is an undercover cop??? #Euphoria"

Now, there's no denying this would be a great plot twist for a new character - I guess we'll have to wait for the rest of the episodes to drop to find out...
