Sarah is sister to Nick Tilsley and half-sister to David Platt, granddaughter to Audrey Roberts and mother to Bethany.
Sarah's storylines have included a controversial and ground-breaking underage pregnancy which saw her giving birth to Bethany Platt and saw Sarah deal with motherhood in her teens..
She hit back at Todd by sleeping with his brother Jason.
While in Milan she divorced Jason.
And now she's returning! This could be fun. I can't wait to see Eileen's face.
