Hollyoaks airs new Silas twist for evil Bobby Costello

 Felix is in trouble...

Hollyoaks has once again referenced serial killer Silas Blissett as Bobby Costello's downward spiral has continued.

The boy has shown violent tendencies like his grandfather, most recently murdering Verity Hutchinson to protect the secret that he allowed Sylver McQueen to die in the patisserie fire.

In Wednesday's (December 21) first-look episode, Felix found John Paul passed out drunk in the Price Slice after relapsing.

Felix showed him kindness by calling a support group to help John Paul cope. With Felix's encouragement, John Paul then faced his family and explained what happened.

John Paul announced he was going straight to a support group meeting and then would enter treatment. Felix explained that "John Paul's biggest worry" was ruining Christmas so he encouraged the McQueens to still try and enjoy the day.

"It's a deal, as long as you stay," Mercedes told Felix.

Throughout the day, Bobby grew more and more jealous of his mum spending time with Felix rather than him.

Sally interrupted Felix and Mercedes just as they were about to share a kiss under the mistletoe by ringing the dinner bell.

"I like having you on the team," Mercedes warmly assured Felix.

Bobby continued to stew over his mum's new love interest, with a sinister cliffhanger showing the boy reading a letter from his dead serial killer grandfather Silas, in which Silas told Bobby: "When it comes to protecting what you hold dear, there is no measure too drastic. So if something you value is under threat, you must eliminate whatever stands in your way – by any means necessary."

What terrifying revenge is Bobby planning now?
