Hollyoaks' Warren Fox has made a shocking discovery in tonight's first-look Hollyoaks as he realised that Sienna Blake is working for the dangerous criminal known as The Undertaker.
With Ethan (Matthew James-Bailey), Sienna (Anna Passey) and Ste (Kieron Richardson) all feeling the pressure after Leela (Kirsty-Leigh Porter) became the prime suspect in Maya's murder, the trio soon concocted a plan to get rid of the incriminating evidence from the police station.
In Monday's episode, however, Ethan was left desperately trying to cover his tracks after his nephew Sam (Matthew McGivern) confronted him for stealing his police uniform, all while an unaware Sienna was trying to prove her worth to criminal boss The Undertaker – aka Norma.

"I'm done trying to fit into this decent, respectable mould," Sienna told Norma. "It just doesn't fit."

Unfortunately for Sienna, however, she soon discovered that Ste forgot to turn off the CCTV footage, forcing her to turn to Norma for help.
"You must know somebody who can destroy that footage," Sienna begged, prompting Norma to issue an ultimatum of her own.
"Maybe I have," Norma replied. "Maybe I see potential in you... But you won't like what I want you to do."
"If it means keeping my freedom, name it," Sienna countered.
Soon enough, Norma revealed her condition for helping Sienna: she tasked Sienna with taking over the finances on the stall, hurting her sister Liberty in the process.
"I would worry about the financial stability of the business if I left it in your hands," Sienna told Liberty while a confused Warren watched on.
"I had to do what's best for the business," Sienna insisted, before she confirmed to Norma that she'd taken over the accounts at the stall as she'd asked.
Later, it was confirmed that Sienna's actions had earned her results too, as Norma succeeded in wiping the footage before Sam was able to look back through the CCTV to discover what they had been up to.
As Warren vowed to Libby that he'd figure out Sienna's secret, it wasn't long before Warren made a discovery of his own.
At the end of the episode, Warren saw Sienna and Norma in the middle of a secret exchange and realised that the pair were working together.
Will Warren confront Sienna with what he knows?
