Steph strikes gold when she discovers a secret about her love rival's past and uses it to ensure that Lucas (Scott Major) calls off his plans to marry Vanessa (Alin Sumarwata).
Upcoming Neighbours episodes see Steph do some digging into Vanessa's background, as she is determined to reunite with Lucas herself. In doing so, she learns that Vanessa was once married to a guy named Alek Poccoli.
Realising that Lucas has no idea about this, Steph sneakily exposes the secret by setting up a fake Facebook profile as Alek and sending Lucas a message.
When Lucas finds out the truth, he can't believe that Vanessa (Alin Sumarwata) kept it a secret and declares that their own wedding is off.
Carla Bonner, who plays Steph, told TV Week: "Steph thinks Lucas calling it off is proof of their instability. If they were tight enough then none of this would actually matter or cause turbulence, but she's seen first-hand how this can derail them."
Steph is now back on screen in Australia and reappears on Channel 5 in the UK from Monday, May 13.
Her return storyline is expected to explore mental health issues as Steph's behaviour becomes increasingly erratic following her release from jail.
