In Season 2, Episode 4 of "Bad Sisters," Houlihan stumbles upon Becka at one of Matt Claffin's captivating performances. Becka confides in Matt, revealing that she has been deemed a "person of interest" in the ongoing investigation. Intrigued, Matt demands further details, making it clear that he cannot shield her this time. As the conversation concludes, Becka heads to a drugstore and purchases a pregnancy test, her mind swirling with thoughts.
Meanwhile, at the beach, the Garvey siblings confront Angelica, accusing her of exploiting Grace's vulnerabilities for personal gain. Angelica responds with a chilling remark, hinting that their hands are not clean either.
Becka suggests to her siblings that they break into Angelica's home to retrieve the $20,000 they believe Grace gave her. They devise a plan to execute this while Angelica is at church with Roger.
Elsewhere, Eva attends Blanaid's rugby match, leaving the others to carry out their plan. At the match, Eva spots Angelica gifting Blanaid a brand-new helmet before departing for church. However, the match takes a tumultuous turn when a parent confronts Eva, and a teammate bullies Blanaid, culminating in a fiery altercation on the field. Molly, Ursula's daughter, steps in to defend Blanaid but ends up getting struck in the face.
Ursula keeps a discreet watch on Angelica during the church service, while Becka and Bibi proceed with their break-in. Roger unexpectedly encounters Angelica and buys her alibi of being lost in prayer. Seeing this as a divine sign, Roger asks her out, but his proposal is marred by insulting undertones. "Let's be frank," he remarks, "are we really destined to find the perfect woman?" Angelica politely but firmly declines.
Returning to the match, Blanaid is furious with Eva for her altercation with the parent, fearing that this will overshadow her performance and become the talk of the town.
Ursula makes her appearance, having deserted her duty upon discovering her daughter's mouth had been struck. During their illegal entry, Bibi and Becka piece together snippets from newspapers revealing that Angelica's husband had deserted her for another woman before his demise. Additionally, they uncover her involvement in a protest fueled by homophobia. Yet, the most disturbing revelation is that Angelica has maintained a room in her house solely for Blanaid.
As Angelica nears her doorstep, Becka is suddenly overcome with morning sickness, compelling her to rush to the bathroom. Bibi manages to escape, with Angelica's pet rabbit in tow, but Becka is trapped in the bathroom with Angelica's arrival imminent. Desperate, she flees the house, her hoodie drawn tightly over her face for concealment.
Elsewhere, Houlihan discovers that the Garvey sisters had stayed in a hotel a mere mile from John Paul's murder scene on the fateful night. Convinced of their involvement, her next objective is to extract a confession from one of them.
The sisters confide in Ian that Grace had been under Angelica's blackmail. Bibi and Becka soon arrive, acknowledging their botched break-in but sharing their findings. Unfortunately, Angelica recognized Becka, prompting detectives to arrive and arrest her for burglary and assault.
While Angelica recuperates at home, Roger attempts to vouch for the Garveys, informing her of JP's despicable actions, such as raping Eva.
The remaining sisters congregate at Angelica's place, urging her to retract her complaint against Becka. In exchange for her cooperation, Angelica expresses her desire to scatter Grace's ashes, a poignant final act of tribute.
The detectives grill Becka about JP's untimely demise but are reluctantly compelled to release her, thanks to Angelica's withdrawal of charges. Meanwhile, Houlihan uncovers the truth about the funds Grace secretly withdrew.
As Eva drives Becka home, Becka confides that the authorities are framing them all as accessories to murder. Adding to her turmoil, she reveals her unexpected pregnancy, a secret Joe remains oblivious to.
Later, Becka seeks solace at Matt's, where they nestle into each other's embrace, sharing intimate conversations. She cherishes the ease with which she can be herself around him; he instinctively understands her without the need for words.
Joe's suspicions are confirmed when he catches Becka departing from Matt's place. The suspicious glances exchanged between them at the funeral had already planted seeds of doubt. Confronted, Becka breaks the heart-wrenching news: she can no longer be with him.
Eva, overwhelmed with emotions and seeking a confidant, turns to Ian. He calms her nerves, counseling caution to avoid giving the guards any further pretext to detain them.
Yet, Ian fails to heed his own advice. He confronts Angelica with a stern warning to steer clear of the Garveys, his broad grin twisted into a menacing expression as he strides away, leaving her visibly shaken.
