Guilt Exclusive: Will Luc's First Lie Uncover an Even Bigger One?

There may be trouble on the way for Luc (Zachary Fall) and Grace (Daisy Head) -- especially when she has to confront the possibility that he's not the person she thought he was.

As the search for Molly Ryan's (Rebekah Wainwright) killer continues on Monday's Guilt, Luc prepares for his first big solo art exhibition, but will the revelation that he's been lying to Grace about something major lead to a much bigger reveal about her boyfriend? Perhaps one about what happened to Molly the night she was killed?
