Dr. Sydney Heron, a character played by Kali Rocha, was last seen on Grey's Anatomy on November 8, 2007, in Season 4, Episode 8. Her return has been confirmed for Grey's Anatomy Season 21, which will premiere on September 26, 2024.
Sydney was introduced in Season 2 as a fourth-year resident initially assigned to supervise interns while Dr. Miranda Bailey was on maternity leave. Her character was chirpy, contrary to most of her colleagues, especially Cristina Yang.
During her run, Sydney became part of many storylines, such as being one of the people Izzie Stevens turned to for emotional support after Denny Duquette's death and the awkward moment with Derek Shepherd.

Following her departure in 2007, Kali Rocha kept busy with various television and film acting jobs. Most notably, she starred as Karen Rooney in Disney Channel's Liv and Maddie from 2013 through 2017. She has also guest-starred as Marcy on Man with a Plan since 2016.
She guest-starred in many other series, such as:
