Tina OBrien Reacts to Sarahs Shocking Murder Reveal

said she's been 'a bag of nerves' as she reacted to Sarah Platt being unveiled as Theo Silverton's murderer in a dramatic special episode.

Viewers learned last month that scaffolder Theo (James Cartwright) met his demise after months of abusive behaviour towards his husband Todd (Gareth Pierce).

Although fans knew he died, there was a mystery around who was responsible for his death.

In Monday's episode of the show, Sarah and  Kit Green (Jacob Roberts) were hosting a dinner party when Maria Windass () confronted her husband, Gary Windass (Mikey North), and Sarah over their suspected affair.

It soon becomes clear that their hushed conversations were for a reason, but they were hiding something much more sinister.

A flashback then took viewers back to the night of Theo's murder, when Sarah got a suspicious text from Todd's phone. 

She headed to the flat he had shared with Theo to find the builder on scaffolding, which had been placed outside their home.

Theo prodded Sarah's emotions, bringing up the son she and Todd had lost 21 years earlier. 

But their confrontation went to a darker level when Theo threatened Sarah with violence. 

Sarah defended herself by grabbing a metal pipe, which she hit on Theo’s head, sending him crashing to the ground below.

Upon realising what she had done, she phoned Gary to help her

Now, actress Tina has opened up about her character being responsible for Theo's death.

When asked how she reacted when she read the scripts to discover it was Sarah behind the death, she told ITV: 'I was really shocked, but for me, personally, I completely understand how it happened, why it happened. 

'For me to get into her character and her head, I feel like, in that moment, she didn't feel like she had any other choice.'

She continued: 'I think, based on previous episodes, there were a lot of people who thought Sarah was protecting Gary or that Sarah and Gary maybe saw something that night and were trying to protect somebody else, when in fact it was actually Sarah, which I think will have come as a shock to a lot of people.'

On keeping it a secret from everyone, she said: 'I’ve literally been a big bag of nerves. 

'It's been so difficult, I told my mum and I just recently told Scarlett and my son Beau. Yeah. 

'It’s really hard having to keep it quiet for that long, especially when you're online, you’re seeing all the chat on social media, everyone's saying I think it's such a body, I think this, and I think that. 

'Actually filming these scenes the weeks after have been the hardest thing I’ve ever filmed because I felt like my face looked guilty constantly and I was like, everyone's going to know it's me instantly.

' So that's been really difficult.'

It comes after six suspects emerged - as DS Lisa Swain (Vicky Myers) and DC Kit Green launched their hunt for the killer with intense interrogations.

While the street's residents struggled to come to terms with a murderer living among them, the suspects fight to keep their secrets under wraps as pressure mounts.

Last month, Todd, George (Tony Maudsley) and Gary (Mikey North) were in the firing line under interrogation.

The coming weeks then saw Summer (Harriet Bibby), Christina (Amy Robbins) and Danielle (Natalie Anderson) also under suspicion.

There's no shortage of motives either, with Todd having survived Theo's abuse.

Before Theo was revealed as the dead body, other characters in the frame were Megan Walsh (Beth Nixon), Jodie Ramsey (Olivia Frances-Brown), Carl Webster (Jonathan Howard) and Maggie Driscoll (Pauline McLynn).

Previously speaking to The Mirror, actor James said of Theo's death: 'Something needs to happen to him. He can't go on like that, we need justice.

'Soap is a very moral medium. We want our underdogs to triumph and our baddies to meet their end.

'Being part of the show and the way we have, in terms of the arc Theo has been on, has been one of the great joys and privileges of my life.

'There is the knowledge that sooner or later he will meet his end and then there's great satisfaction.'

Coronation Street airs on ITV1 and ITVX.
