There's heartbreak for Sam's son with Jack Branning, Ricky, as he reels from the news that his long absent mum is back in his life. When they bump into each other at Walford East the moment is awkward.
Upset for Ricky and worried for Jack, Denise Fox warns Sam not to cause problems. But it seems that Denise's warning is about to have the opposite effect when Sam comes up with a new plan and confronts Jack...
Harvey Monroe is on pins about going to see his son Aaron Monroe in prison. He's had several threatening interactions with far right thug Neil Hughes and he's in a dilemma over what to do.
