Spoilers for the fourth episode of “The Penguin” below

Hours before the Falcone family's biggest reckoning of all, Sofia Falcone (Cristin Milioti) showed up at their final dinner and set the touchpaper on fire.

She berates them all for taking her to Arkham State Hospital and confronts them about the crimes she was accused of, namely the deaths of seven women: Summer Gleeson, Taylor Montgomery, Nancy Hoffman, Yolanda Jones, Susannah Weakly, Devri Blake and Tricia Becker. The murders earned Sofia the executioner's nickname in the media.

In last week's episode, Sofia Oz revealed that “I'm not the executioner.” Now we find out what really happened…

The backstory

In the flashback to Sofia's life before Arkham, we learn that her mother died by suicide and that she discovered the body.

Years later, a journalist named Summer Gleeson approaches Sofia at a charity event and asks her to speak. Sofia – who at this point has been assigned to Oz Cobb (Colin Farrell) as a driver – takes her to a meeting with Summer, who tells her that six women have died of asphyxiation, probably from manual strangulation, but the police say it is “Suicide by hanging” had been “.

Summer adds that the women, who were sex workers at the Iceberg Lounge and Club 44 Below, also had marks on their bodies that suggested they had fought, bitten and scratched with someone.

Summer asks Sofia to wear a wire to her father's club or provide access to employee records. But even though Sofia remembers her mother's hands being in the same bloody state, does she also remember noticing scratch marks on her father's hands on the same day her mother died? – She threatens the journalist. “If you publish any of this garbage, my family will destroy you. Do you understand?”

Oz betrayed

When Oz shows up at Carmine's birthday party, he tells Sofia that her father wants to see her in her office. Someone revealed that she went to see the reporter.

Carmine tells her that Summer Gleeson has been cooperating with the police and that there is an ongoing investigation and they believe he is responsible for the murders. Although Sofia says she knows these accusations are “nonsense,” she can't help but bring up the matter of her father's scratched hands all those years ago.

“My dear, sweet Sofia…” he says, “You are confused… sick” and tells her to go. It's all over for her. She is arrested as Oz drives her home – for the murder of Summer Gleeson and six other women.

It was Oz's decision to go to Carmine that got the ball rolling. So, did Oz kill Summer for her father, she asks him? “No, I have no idea what the hell he’s talking about,” he replies, but as we’ve already seen, Oz is willing to lie to anyone when it comes to his own neck.

Did he kill Summer? Possibly, as he may have been sent to do so by Carmine. And if it wasn't Oz, then it would have been another Falcone sidekick. As for the other six women, it's probably the same: either Carmine or one of his henchmen.

Shortly before she is excommunicated and shipped to Arkham, Sofia realizes that Carmine's bodies could be eight women in total, including her mother. No wonder Sofia wanted revenge for the violence against the women in her family.
