You do know that, right? Because you have to trust me if you want to be my lawyer Jane - Did you see that on TV, too? Petra - No. Petra - You're gonna make that whole murder thing go away because I didn't do it.
She asks what Petra will write about Anežka and Petra says she'll need more wine for that. JR doesn't think it's a good idea to publish a book whilst under investigation.
JR drops by to thank Petra with a bottle of wine and Petra's tipsy from trying to write a book. Petra decides to help JR out and asks Krishna to get JR's mother in with a top specialist via her connections at the hospital where he works. When texting with whoever she's working with, Petra gets momentarily suspicious and JR tells Petra about her mother's early onset Alzheimer's. When Petra persists, JR agrees only if she can call her Peter. While they continue working together, Petra's irked by Jane's name and asks to call her JR, which JR declines. She takes Petra's case, but later talks to someone who clearly knows Petra, about the next step now that she's Petra's attorney. JR seems to like that Petra let her guard down and showed her true self, but doesn't let on. Petra gets emotional and explains her situation, how she feels she has no one to lean on. JR returns and Petra thanks her for returning, but JR's dismissive as Petra called her a hack. Once the police show up, things progressing exactly as JR said they would, Petra asks Krishna to get her back at any cost. Petra's a little unsteadied by how her iron will doesn't seem to affect JR, and how the latter is very strong and direct, while JR seems to read Petra easily. Jane doesn't take any of Petra's crap, tells her exactly how Petra's case will proceed and walks out saying she's not interested in the case. When Jane contradicts her, Petra arrogantly asserts that she noticed how rich Petra is and is only after a drawn-out, lucrative case. During their meeting, Petra again dismisses that she needs a lawyer. She is immediately put off when she realizes her assistant's hired a lawyer named Jane. Although she insists that she won't be a person of interest since it was in self-defense, her ex Rafael Solano convinces her to hire a lawyer. When Anežka falls off of the balcony during an argument with Petra in her suite at The Marbella and dies, Petra's brought in to the police station for suspected murder. They reunite again after Rafael contacts JR and she tells Petra she still loves her and haven't stopped thinking about her.
Despite moving past it and growing close once more, JR she ends their relationship after getting a job offer in Houston and deciding she needs a fresh start. They reunite after JR decides to forgive her and Petra promises to never lie to her again. However, in the season 4 finale, Jane Ramos becomes furious and breaks up with Petra after finding out she lied about her involvement in Anežka's death to protect her daughters Anna and Ellie. They start dating after they believe the case is finally closed. They first got together while Jane Ramos was Petra's lawyer during the investigation into Anežka's death.
