6510: Vanessa's mum arrives on Ramsay Street

Vanessa is uncharacteristically rattled by news of an unexpected visitor, and she works to get Lucas out of the house before their arrival. Her strange behaviour gives him cause for concern and he returns home to check on her. However, he's stunned when he busts her with her mother Francesca - and realises that she doesn't know Vanessa is pregnant. A desperate Vanessa works to conceal her pregnancy from her mum, but just as she thinks she has pulled it off, Chris accidentally blows her secret.

Faced with harsh berating from Francesca for being a single mother, Vanessa begins to crumble. Seeing this, Lucas steps up and attempts to lower the impact of the news by presenting himself as the father of the baby - and Vanessa's loving partner. While Francesca buys the lie, she adds to Vanessa's woes by revealing that she's going to stick around to get to know Lucas - they're going to have to keep up the act…

Meanwhile, struggling to accept Summer and Bradley's relationship, a worried Susan enlists Karl to intervene. Karl decides to suss it for himself and imposes on a date, but is surprisingly won over when Bradley speaks to him openly about how much he respects Summer. Satisfied Bradley's intentions are honourable, Karl assures Susan there's nothing to be worried about - but it's clear she is unconvinced.

Elsewhere, after hearing Sophie isn't acting like herself, Chris reaches out and pushes her to reveal that she thinks she brought her injuries on herself, by acting so rebelliously in the lead-up to the crash. Presenting himself as a confidant, Chris urges her to move on. But will it be that simple?
