Coronation Street spoilers follow from Monday’s episode (20 April), which is available to watch now on ITVX and YouTube but hasn’t aired on ITV1 yet.

Coronation Street has fuelled a fan theory suggesting that Summer Spellman could turn murderous in the coming fortnight.

Viewers are watching Summer closely as the ITV soap gears up for a shocking new killer mystery, which will see one villain lose their life.

Theo Silverton is among the five characters who could be about to die – and if the story does go this way, there’d be no shortage of suspects.

In tonight’s episode, Theo targets Summer during a sinister visit to the corner shop. He even locks the door, hoping to intimidate Summer as they’re left alone together.

Annoyed that Todd Grimshaw’s loved ones have been plotting his downfall, Theo tries to goad Summer, but she warns that she’s not to be messed with.

“Confident – never seen this side to you before,” Theo notes. “Didn’t know you had it in you.”

Summer ominously replies: “You have no idea what I’m capable of…”

Theo quips that it’s “always the quiet ones” – could the show be setting the stage for a more ruthless version of Summer? As she even gets physical with Theo in full view of the shop’s CCTV camera, the confrontation could look damning later on.

Shortly afterwards, the show gives Summer another motive for wanting Theo gone as he threatens her life.

Recalling how he left Billy Mayhew to die in the Corriedale crash, Theo mocks: “You should have seen Billy’s face when he was pleading for his life. ‘Our father who art in heaven’. Pathetic, really.

“Todd is mine. Don’t make me bury you, too.”

Could Summer get rid of Theo to protect herself and Todd? Or could one of the other four characters – Carl, Jodie, Maggie or Megan – be the mystery death?

Coronation Street airs on weeknights at 8.30pm on ITV1 and streams on ITVX.
