Lloyd receives a shock in Friday night's double bill of the soap as he discovers that girlfriend Cheryl Gray (Holly Quin-Ankrah) has been cheating on him with her ex-partner Chris.
Chris (Will Thorp) reveals the affair to Lloyd after the cabbie starts to get suspicious over his illness, accusing him of exaggerating his condition after discovering that he has lied about having a hospital appointment. Lloyd is immediately devastated by Chris's revelation and decides that he must have been wrong with his original theory.
Charles told itv.com of the latest plot developments: "Lloyd's about to tell Cheryl, 'He didn't have an appointment, there's nothing wrong with him, he's pulling the wool over our eyes and he's not even sick'. Chris knows that [he's] going to do this, so he pulls out his trump card.
"Things are going to get a lot worse. Lloyd's going to have a proper breakdown - he takes this really, really badly."
However, Charles also warned that Chris is likely to get his comeuppance for hiding the fact that his brain tumour has receded.
He said: "Chris has made a rod for his own back, because at some stage, it's got to come out that there's nothing wrong with him. And who knows what's going to happen after that? Will Cheryl then try and come back to Lloyd? Will Lloyd take her back? Watch this space!"
Coronation Street continues tonight at 7.30pm and 8.30pm on ITV1.
