Coronation Street viewers believe they have uncovered the real reason behind Sarah Platt's erratic behaviour. The character has been acting strangely since an attack weeks ago, lashing out at colleagues and appearing visibly shaken, though she insists she is fine.
Sarah's boss Carla Connor urged her to take time off, but Sarah turned to alcohol to cope. Fans have speculated that her issues may stem from trauma or a head injury, but a leading theory suggests her behaviour is unrelated to the attack.
Some viewers think Sarah may be hiding a secret linked to Theo Silverton's murder. Theories include a possible fling with ex Gary Windass, or that she knows who killed Theo. One fan said: 'I get the feeling Sarah either killed Theo or knows who did.'
Another added: 'Does she know more about Theo's death than she's letting on.' A third suggested Sam may be the killer and Sarah saw something, causing her to act out to protect her nephew. Others believe Sarah herself committed the murder.
Alternative theories include an undiagnosed head injury or PTSD from the attack. Meanwhile, Summer Spellman is the prime suspect in Theo's murder due to her journal entries, but some wonder if she is being framed.
Coronation Street airs weeknights at 8:30pm on ITV1 and ITVX.
