Having got form to getting her hands on large sums of cash before, it would not be totally out of the blue for Cassie to take it to the extremes to get what she wants.
Specualtion is now rife that she could turn killer in order to bump off Ken and secretly take his money.
Commenting online, one fan said: "So Cassie's going to knock Kenneth off then? I wondered why they'd randomly put her in there."
Another added: "#Cassie has to slowly drug Ken so he grts brain addled in order to get her hands on his bankcard /password out of him which seems the obvious but it backfires."
Viewers watched as Cassie thought she was asked out on a date by Steve McDonald and quickly transformed herself.
A fresh-blow dry, a nice top and a denim skirt - as well as a full face of make-up - made Cassie look every bit as glamorous as actress Claire is off-screen.
Darkest soap storylines
Over the years the likes of EastEnders, Emmerdale and Coronation Street have all tried to try outdo each other with their outlandish plots in a bid to keep us tuning in each week. But here are some of the darkest that had fans in shock...
EastEnders: Tony grooming Whitney (2008-2009) - Tony King first appeared in Albert Square in 2008 as the boyfriend of Bianca, played by Patsy Palmer. But it was quickly revealed he was a paedophile who had been grooming vulnerable Whitney, Bianca’s adopted stepdaughter from a previous relationship, since she was 12. The shocking storyline attracted more than 200 complaints within a week of it beginning. Whitney waited until her 16th birthday to reveal the truth to a horrified Bianca, who called the police.
Emmerdale: Holly's drug addiction and shock death (2010-2016) - In 2010, Holly Barton (played by Sophie Powles) became Emmerdale's first teenage drug addict. The shocking storyline saw her taking cocaine on a night out before developing a deadly heroin habit. Parents John and Moira desperately tried to help get their daughter clean but when Holly returned in 2016, following a four-year absence, she quickly relapsed. Fans were left stunned and heartbroken when distraught Moira found Holly dead in her bed from a heroin overdose.
Hollyoaks: Luke's rape (2000) - Actor Gary Lucy was just 17 when he took on this groundbreaking storyline, which saw his character Luke Morgan become soap’s first male rape victim. Luke had endured a long-running bullying campaign by football rival Mark Gibbs - who raped him after Luke stood up to him. Luke was left suicidal following the brutal attack, before opening up to his brother Adam. Gibbs was sentenced to eight years in prison. Gary won the Best Actor gong at the British Soap Awards in 2000 for his performance.
Coronation Street: Evil Richard Hillman (2001-2003) - Just a mere mention of ‘Richard Hillman’ is enough to send a shiver down the spines of soap fans. He is often ranked one of the most evil soap villains and it’s not hard to see why. The smooth-talking financial adviser bashed his ex-wife Patricia over the head with a shovel. In a bid to keep his mother-in-law Audrey quiet, he set fire to her house. And when Maxine caught him trying to murder Emily Bishop, he took a crowbar to her head. He made his exit from the cobbles in 2003 when he drove Gail Platt, played by Helen Worth, and her family into the canal. They survived, but he didn’t.
