Emily Kmetko is played by the famous actor known as Chelsea Hobbs
Coach Marty Walsh recruited Emily to The Rock after seeing her practicing gymnastics at the YMCA in Fresno. In addition to her gymnastics training, she works nights and weekends at The Pizza Shack to help support her family financially.
Emily falls in love with her coworker at The Pizza Shack, Damon Young, an aspiring songwriter who at first is too scared to sing his own music. She becomes a member of the National Team and later is chosen for the World's Team, but her career is jeopardized when she is arrested for stealing her brother, Brian's, medication and by having a job at the Pizza Shack.
She has intercourse with her boyfriend, Damon, and following a few weeks later, she breaks up with him, only to find out at the Hungarian meet that she is pregnant with Damon's child. (Chelsea Hobbs was pregnant in real life with her second child a baby boy, so they wrote it into the show)
Emily later quits gymnastics as she decides to keep the baby and go to Las Vegas to live with her godmother. Emily strives her entire life to leave a legacy unlike her mother, Chloe, yet winds up living it just like hers.
