This marks the return of China White, last seen in Season Two, and Cupid and Liza Warner, both of whom last appeared during Season Four. The episode is titled "The Sin-Eater," a reference to a person who, in some culture, consumed a ritual meal in order to magically assume the sins of a person or a household, thereby absolving their souls.

CHINA WHITE, CUPID AND LIZA WARNER BREAK OUT OF PRISON — China White (guest star Kelly Hu), Cupid (guest star Amy Gumenick) and Liza Warner (guest star Rutina Wesley) break out of Iron Heights and head to Star City for revenge. Oliver (Stephen Amell) tries to bring in the newly formed girl gang but the ACU intervenes mid-fight. To his surprise, they are there to arrest the Green Arrow for the murder of Detective Malone. Meanwhile, Lance (Paul Blackthorne) feels responsible for the prison break after Warner tells him she heard about him working with Damien Darhk. Mary Lambert directed the episode written by Barbara Bloom & Jenny Lynn.

Airing Wednesdays at 8 p.m. ET/PT on The CW, “Arrow” stars Stephen Amell, Emily Bett Rickards, David Ramsey, Willa Holland, Paul Blackthorne and Echo Callum.
