The actor's sinister character Silas Blissett murdered student India Longford last Christmas after making contact with her online and arranging a meeting.
Silas returns to his old tricks in next week's episodes of the Channel 4 show when he starts using the same methods on newcomer Jenny, played by Daisy Turner.
Speaking to Inside Soap, Rawle commented: "It's an ongoing message we're trying to put out that the internet can be a dangerous place. Silas could be grooming up to 200 girls, waiting for just one to let down their guard - and that's where Jenny comes in."
As previously revealed, Jenny is hoping to con Silas but her scheming goes horribly wrong when she discovers his dangerous intentions as they have a picnic in the woods, leaving her in serious danger from which she may not escape.

Speaking of Jenny's ill-fated plan, Rawle added: "She'd have to be very audacious to outsmart someone who has been a killer for quite some time now. Silas is beginning to believe that he's invincible, but eventually he'll have to be brought to justice. The big question is: when?"
As well as killing India, Silas has previously come close to bumping off Nancy Hayton, Texas Longford and Lynsey Nolan.
