Mona was Ross's recurring girlfriend in season 8. She first appeared in "The One After "I Do"". Mona and Ross began their relationship just as Ross learned that Rachel was pregnant with his child. However, when Ross asked Rachel to move in with him because of the baby, Mona broke up with him.
Her relationship with Ross was often plagued with unfortunate coincidences, such as Ross giving her a key to his house before being forced to change the locks and her finding out on Valentine's Day that Rachel had moved in with him.
Mona's relationship with Ross could be described as more friendly than romantic even when they were dating. Ross takes things a lot more slowly with Mona than he did with other girls. A few instances of this was when he was willing to adopt a cat with Julie, and proposed to Emily after dating for only two months. In contrast, Ross had met Mona in May during Monica and Chandler's wedding and in "The One With Ross's Step Forward", which takes place in December, he was trying to dissuade her from sending out holiday cards. Their relationship later became complicated due to Ross being the father of Rachel's baby and Ross regularly forgetting dates with her when Rachel had pregnancy problems Their relationship ultimately ended on Valentine's Day in "The One With The Birthing Video". Two episodes later, Ross sneaks over to Mona's apartment to retrieve his favorite salmon shirt when she returns with another boyfriend. During the credits, Mona comes over to his apartment because she thinks she still has feelings for him (but that wasn't it; he only wanted his shirt back). She asks if she can keep the shirt to remember him but Ross says no.
Mona also seemed to have a good relationship with Rachel. She was very supportive of Ross and Rachel having a baby (she even bought a t-shirt that says "Fossils are my friends"), but wasn't happy that Ross was forgetting about her when Rachel was having baby trouble, although they still maintained a good friendship (But it could be possible that Rachel secretly disliked Mona because Ross had abandoned her for Mona during pregnancy and Rachel was wanting to talk to him about the possible re-kindling of a relationship, but this was mostly unlikely- Even in Season 2, Rachel despised Ross's girlfriend Julie because she was in love with Ross at the same time). Mona didn't even attend Rachel's baby shower, but that was because her appearances in the show were finished.
Mona and Monica were colleagues at Allesandro's. Although they do not interact much onscreen, it is implied that they have a good relationship since Mona was invited to Monica and Chandler's wedding as well as their Halloween party. It is unknown if they ever saw each other again after Monica left Allessandro's to try and live with Chandler in Oklahoma before returning to New York to get a job as head chef at Javu.
Chandler Bing, Phoebe Buffay, and Joey Tribbiani
Mona also seemed to have a good relationship with Chandler, Phoebe and Joey. Joey tried to hook up with her the night of Chandler and Monica's wedding, but Ross deterred him by pointing out his small feet.
Mona showed particular dislike for Rachel's father Dr. Leonard Green after the harsh doctor charged into Ross's apartment and started shouting at him about getting Rachel pregnant and not marrying her afterwards. She was very offended after Dr. Green called her a tramp and was hoping that her relationship with Ross would not end while Ross and Dr. Green were bickering about Rachel (Ross couldn't tell Leonard the truth because he knew it will upset Mona). As for that, Mona and Dr. Green hated each other the same way Ross and Dr. Green do.
Mona had a new unnamed boyfriend sometime after she and Ross broke up and the relationship was obviously a good one when they are seen passionately making out on the couch after Mona gives him Ross's salmon shirt to wear after she accidentally spilled wine on his other shirt. The relationship goes on well but it is unknown how long it would continue.
