Coronation Street newcomer Danielle Silverton realises her husband Theo is playing away next week – and accuses Sarah Barlow of sleeping with him.

Having discovered that Todd Grimshaw and Sarah aren’t together after all, Danielle puts two and two together, and assumes Sarah is after her man. But is she about to find out just how far off the mark she is when she walks in on Theo sharing a moment with Todd?

“When Danielle discovers that Todd is gay, she jumps to the conclusion that it’s Sarah having a bunk-up with Theo,” our Corrie source explains.

“Danielle tears a strip off Sarah, who is caught in an awkward situation as she doesn’t want to expose Todd. But her efforts might be in vain when Danielle later catches Theo and Todd together…”

The problems unfold after a sneaky lie from Todd and Theo. After discovering that Theo was married with kids, Todd ends up roping Sarah into his secret romance when she pretends to be his girlfriend to put Danielle off the scent. However, Todd starts to rather enjoy the ruse, planting a kiss on Sarah to wind up Theo.

His actions only make things more complicated for all concerned, though. So when Danielle spots Sarah flirting with Kit Green, she’s outraged to think Sarah’s cheating on poor Todd, leaving George bemused…

“George quickly puts her straight on Todd being not straight,” our insider adds.

“Danielle is thrown by this revelation, and when she spots Sarah having a quiet discussion with Theo, she decides Sarah must be at it with more than one man – including her husband.

“When she sees Todd and Sarah later, she rails at them over their sham relationship and accuses Sarah of having it away with Theo. The whole thing is one big mess.”

It’s clear the situation has put a bomb under Danielle and Theo’s marriage, and he angrily accuses Todd of ruining his relationship. But as Danielle and Sarah clash again, she tells the angry wife that she should be looking to Todd for answers.

Meanwhile, Theo is at the factory ending things with Todd, telling him that it would be better for all concerned if they stay out of each other’s way from now on. However, little do they know that Danielle is on her way to find them…

“Theo’s insisting things are over, yet it’s clear there’s a real connection between him and Todd,” our source teases.

“So will Theo have the strength to follow through with his promise? Let’s just say Danielle could be in for a huge shock…”
