Pascal’s Date Falls Flat

She later apologized, claiming work got in the way — but it was clear both were struggling to balance their demanding careers and personal grief.

Vasquez Steps Up — and Struggles

With Kidd still on furlough, Violet took Vasquez under her wing. Determined to prove himself, he filled in for Novak and joined the paramedic team on several calls, including a tense rescue at a local school where a teacher was trapped inside a smoke-filled classroom.

While Squad 3 saved the teacher, Severide (Taylor Kinney) immediately sensed something wasn’t right. His instincts were spot-on — the fire was no accident.

During their downtime, Violet coached Vasquez on starting IVs, and for the first time, he followed her instructions without pushback. It was a small but hopeful step toward maturity — though his confidence would soon be tested by the unexpected return of a face from his past.

Severide’s Suspicion Proves Right

Severide and Van Meter’s investigation revealed a disturbing detail: the coffee machine that started the blaze had been connected to a smart plug, meaning the fire was triggered remotely. That revelation ruled out their main suspect — suspended student Wyatt — who had been at a basketball game during the incident.

Still, the boy knew more than he let on. Digging deeper, Severide discovered an online hate group targeting the school’s principal, with more than 80 active members. The OFI team was left with a terrifying realization — the arsonist could be anyone.

Novak’s Family Pain Resurfaces

Elsewhere, Lizzie Novak (Jocelyn Hudon) faced a different kind of emergency. Her sister Heidi was hospitalized after accidentally mixing medication with alcohol. The incident exposed years of buried family tension — and revealed why Novak had distanced herself from her siblings.

Their confrontation at the hospital was raw, exposing Novak’s guilt over “always being the caretaker” since their mother’s death. Later, she decided to try again, showing up at Heidi’s door with a bottle of wine and a quiet olive branch.

It was a tender moment that humanized Novak more than ever, hinting at layers of trauma and resilience beneath her tough exterior.

Meanwhile, Mouch’s idealistic plan to modernize the city’s firehouses hit a bureaucratic wall. Pascal admitted the proposal wouldn’t translate into funding — and moments later, Annette dropped the bombshell: Engine 51 is being permanently cut due to budget reallocation.

Just as Mouch earned his long-awaited bugles, it seemed his station’s legacy could be wiped out entirely.

Severide’s Case Ignites — Literally

As the episode closed, Severide and Van Meter met with the principal at his apartment to discuss new leads — unaware that in the stairwell outside, someone was pouring accelerant and lighting a match.

The flames roared to life, trapping them inside and setting up a pulse-pounding cliffhanger.
