As previously revealed, killer Silas will soon choose Lynsey as his next target, breaking into her flat with murder in mind.
However, before things can go any further, Silas is scared off as Lynsey's screams alert Riley to the situation and he arrives to rescue her. Silas escapes without detection, but Lynsey soon realises who was responsible for the incident.
Speaking to Bang Showbiz about the plot twist, Waugh explained: "Everyone thinks she's crazy and making it up, as does Cheryl at first. Lynsey's really upset about it and asks Cheryl for some help. While she hates seeing her best friend in that kind of state, she thinks Lynsey's just being paranoid and Silas is a really upstanding member of society.
"It will all be quite dark and will escalate to a boiling point when Cheryl is devastated to find out [Lynsey's] been attacked. She'll try to look after her and protect her but she does feel a little guilty that she didn't do anything sooner."
She added: "It's all very dramatic and I'm sure it will have viewers shouting at their TV screens."
