Spoiler alert: This article contains spoilers for Season 9 of Chicago P.D.
Season 9, Episode 21 of Chicago P.D. explores Sergeant Hank Voight's increasingly fraught relationship with Anna Avalos (Carmela Zumbado), who goes on an undercover mission to help expose the shady dealings of a drug kingpin named Javier Escano (José Zúñiga). The precarious project may drive a wedge between Voight, Anna, and the rest of the team. What's next? Who is leaving Chicago P.D. ahead of Season 10?
Rumors about actress Tracy Spiridakos's departure from 'Chicago P.D.' have been rampant for a while.
Season 9 of Chicago P.D. throws a major curveball to several characters. Season 9, Episode 21 revolves around the strange dynamic between Voight and Anna — which only accelerates as they continue to work hard to dig up intel on the dirty work carried out by Escano. The same episode also casts doubt on Hailey Upton's (Tracy Spiridakos) future. The detective suffered severe injuries as a result of an explosion. Is Hailey going to die? Will she be in Season 10?
In Season 9, Episode 21, Upton and Jay Halstead (Jesse Lee Soffer) try to monitor Mateo Vega (Roggi Chuquimarca). At one point, Upton and Halstead are left with no choice but to stop Mateo in his tracks — thereby putting the whole operation at risk. Adam Ruzek (Patrick Flueger) scores a rare victory during a face-off between Escano's men and the police — but the tension-filled scene gives way to something even worse.
An explosion nearly costs Upton's life. "If the explosion is the final scene tonight and then the promo ends with Hailey on the floor and a Jay voiceover? 'Hailey!'" tweeted @vpstead.
Right now, it's unclear whether Hailey will make a full recovery ... and what Tracy's future on the show looks like.
Tracy Spiridakos has played Hailey Upton since Season 4, Episode 21 of 'Chicago P.D.'
Tracy joined the cast of Chicago P.D. a few years back, portraying the sharp-witted, enviably confident Hailey Upton, who came to replace Voight's daughter, Erin Lindsay (Sophia Bush), on the team. Over the years, Tracy's on-screen character has undergone considerable changes. After years of heated flirtation, Hailey and her romantic interest and co-worker, Jay Halstead (Jesse Lee Soffer), tied the knot in Season 9, Episode 9 of Chicago P.D.
Tracy Spiridakos, the actress playing Hailey Upton, recently joined the cast of 'Byrd and the Bees.'
A police procedural veteran, Tracy has appeared on TV shows like MacGyver before joining the cast of Chicago P.D. With decades of experience under her belt, Tracy has proven time and time again that she is a phenomenal actress.
As Season 9, Episode 21, and a new promo for the Season 9 finale suggest, Upton's life is very much up in the air. Let's hope that nothing major will happen to Upton in the Season 9 finale — and that Tracy will promptly resume her role on Chicago P.D. in Season 10.
There's a chance that the storyline about Upton's recovery will buy Tracy enough time to shoot Byrd and the Bees — and that she'll be able to return to Chicago P.D. full-time in the future.
