Silas has spent weeks terrorising Lynsey as she has correctly worked out that he is the evil killer who has claimed three victims in the village.
Praising co-star Karen Hassan, who plays Lynsey, Rawle told We Love Telly: "She's amazing. She's so good in this it's not true. I spent so many hours being mean to her, I felt bad!"
Silas steps up his twisted games with Lynsey in this week's episodes as he orders her to guess who his next target is, promising that he will hand himself in if she works it out. However, if she fails, another girl will die.
Rawle continued: "He loves all the melodrama and cheap horror. He can't get enough of this kind of schlocky plot and really enjoys toying with Lynsey. He gives her all these clues about who he's going to kill next, like she's a contestant on 3-2-1."
Asked whether viewers can figure out Silas's target, he replied: "Yes, I suppose so. If you put it together. There's one clue in particular that might help you."
Hollyoaks airs weeknights at 6.30pm on Channel 4 and 7pm on E4.
