Pretty Little Liars Wiki

Monily is the friendship pairing between Emily Fields and Mona Vanderwaal. The two had known each other since before the events of The First Secret, but didn't become friends until Taking This One to the Grave. Due to Ali's dislike for Mona, the two didn't talk all that much and only began to once Mona was popular alongside Hanna.


The relationship between Mona and Emily started out under bad pretenses, as Emily was friends with Alison DiLaurentis, Mona's High School bully and tormentor. Emily often stood by as Alison bullied Mona, never intervening or stopping Alison. It wasn't until later, when Hanna, Emily, and the other Liars became friends again, that Emily and Mona started interacting once more. This time, it was friendlier and more helpful; Mona even helped Emily get back on the swim-team. After Mona was revealed to have been A, and the one who tormented and stalked Emily, she never fully trusted her again. They briefly became friendly again before Mona's mysterious "death", and helped one another escape A's Dollhouse. Mona later helped Emily find out who performed the insemination procedure on Alison, which brought the girls a little closer, until Mona was revealed to be Charlotte DiLaurentis' killer. The two are currently friendly for the sake of Hanna.



Aria asks Emily if that's Hanna, as she doesn't recognize her at first due to her make-over. Emily informs her that Hanna is the new "It-Girl", and then points out Mona, informing her that the two are best friends now.

The Naked Truth

At school, Emily is on break and when she returns she talks with Mona about Hanna. Everyone still believes that Hanna sent that picture, and Mona tells her that people are toads. A moment of silence passes, before Emily tells her that she knows that she heard what Mr. Tamborelli told her during break. She apologizes for standing by and letting Alison bully Mona, saying that's she isn't proud of it and is sorry that she didn't try to stop her. Mona pretends that it doesn't affect her, and tell her that she's not holding onto it. She tells her that what bothers her is how Tamborelli is treating her, and says that if Emily was a guy she'd be back on the swim team already. Emily asks what she means, and Mona tells her that considering how much slack he cuts for the football team she should be back on the team by now. She tells Emily that she knows a lot from her former job working in the vice-principals' office, and that Emily should know things too.
Later that night, Emily goes into Tamborelli's office, where she is greeted by Mona, who asks Emily to close the blinds. Emily asks why they are there, and if Mona was the one who called her up there, realizing it was Mona's voice over the speaker. Mona calls it a gift, and says that she is going to help Emily get back on the swim team. She hacks into Tamborelli's computer, but notices that Emily is nervous and offers to stop. After a moment, Emily tells her to keep going.
After some hacking, Mona uncovers that Tamborelli accepted a generous bribe from the father of a football player who got kicked off the team. Mona states that they can use the fact that he took the bribe to get Emily back on the team, and prints the evidence and says they are going to use it to get Emily back on the team. Emily initially doesn't want to blackmail someone, especially a school official, but Mona says that she, "can't be a shark if she's toothless."

Emily sees Mona talking with Tamborelli down the hall, and is concerned when Mona approaches her and tells her that it is done. Mona says she told Tamborelli that she found out about his bribes because the football jocks talk a lot when they aren't on the field. Emily is worried that Tamborelli will find out the truth, but Mona assures Emily he won't, and congratulates her on getting back on the team. Emily asks why she helped her, and Mona says it was fun and that's what friends do. Mona says that she now needs Emily's help, and asks what people wear to swim meets, since she's worried about ruining her wedges. This make Emily laugh and smile, before Mona walks off.

Misery Loves Company

Emily is in her car outside of Rosewood High School, waiting for Caleb as she had plans to follow him. She sees Mona exit the school and watches her for a moment. When Mona looks in her direction, Emily crouches down in an attempt to hide, and Mona has a hard look on her face before she smiles and joins her friends. Emily watches Mona sit down at a table with a group of people, and then leaves to follow Caleb.

Under The Gun

Emily confronts Mona during lunch, and tells her that she wants to know what A has on Toby. Mona comments that everyone like to know, and Emily tells her that she wants in. Mona doesn't understand what she wants in on, and Emily tells her that she wants in on whatever it is that Mona is doing. She lists things that Mona knew or was ahead of, and says that she has the fast-track on A while everyone else is lost. Mona sighs and admits that she isn't the one pulling the strings anymore, and that everything that they've both done, A has proof of. If they make one wrong move they all go up in flames, and Emily walks away a few seconds later.

Cover For Me

Mona is pulling out of her garage when she notices that Emily is directly behind her. She slams on the breaks seconds before she could hit Emily. Emily walks around the car to the drivers side and states that she needs to talk to her, and Mona curtly says that she has somewhere to be. Emily asks if she's meeting with Ezra Fitz, which both surprises and annoys Mona, and she tells her to get in.

Once Emily is in the car, Mona admits that she's surprised that it took her this long to figure out that she is working with Ezra. She admits that she thought it would be Aria, and that Ezra should have told her about the book a long time ago. Emily asks her when she found out, and Mona admits that she's known for a while, and found out around the time that she bought Jenna's car. However, she didn't want to help him with the book, she wanted to stop him or at least stop the parts that included her. Some of the things she did she could still go to jail for, so the pair made a deal. She would tell him about her exploits and he would edit out anything she did that was illegal. Emily asks if she's read the book, and what it says about Alison. Mona admits that she hasn't read Ali's parts only her own, but if Alison were her she would probably love being a part of a scandalous page-turner.

Emily asks if the only reason she dated Mike was get to close to Aria, and Mona seems saddened about this. She states that Mike is a really nice guy and that she did fall for him, but when the Liars started catching on she told Ezra she wanted out, but he told her that getting out wasn't an option. She didn't want to drag Mike into her mess so she broke-up with him, and Emily asks if she really went through all that and got nothing. But Mona insists that she got something, something merky but big. She asks Emily if she remembers after the Lodge fire when she told them all that someone stole the game from her, and Emily says that they thought it was CeCe Drake. Mona admits that she never found out, but whoever it is, Ezra thinks he knows.
