Veronica "V" Fisher is one half of the Gallaghers' closest neighbors, the other half being husband Kev. Sharp and sexy, Veronica is usually willing to lend a hand, go dancing with best friend Fiona or party with Frank. She has intelligence to match her beauty and is very knowledgeable when it comes to medical issues. She had potential to become a nurse, however was fired from her nursing home for stealing supplies.
In Season 1 episode Casey Casden, Kev pretended to be engaged to avoid the attention of a flirty girl at the bar, but his lie quickly spun out of control when Frank overheard and took him to be serious. Frank quickly announced the news to the whole bar, including Veronica's mother Carol who was ecstatic at the news.
Kev spent the next few hours getting badly drunk while talking to Carol and agonizing over what to do. Hearing from Carol how much Veronica loved him he decided to drunkenly propose to her. Veronica was just as ecstatic as her mother and after first checking if he was serious, she happily accepted and left him to sleep off the booze. She soon woke so they could get drunk again though, taking him to an impromptu party at the Gallaghers to announce their happy news.
However while a happy Veronica partied, she was oblivious to Kev's strange behavior. Sitting alone and looking unhappy, Kev drew the attention of Fiona, who after telling him just how happy she was to have Kev and Veronica in her life, joked that he looked very unhappy for someone who had just got engaged. Fiona was left reeling when Kev quietly told her that he was already married!
In Season 3 episode 2 Veronica was helping Fiona with promoting the club where she worked at. Kevin's wife makes an appearance with her son who may not be his (not yet mentioned during the episode). Veronica asked Fiona if she can stay over at the Gallagher's house sitting in the front porch crying possibly because she knows about Kevin's marriage. In the next episode Veronica is having a hard time dealing with that fact that Kevin is the father and her relationship with Kevin is put into dismay as Kevin tries to know his would be son. Near the end of the episode Sheryl the wife of Kevin reveal that her named son Kyle was her sister's and Veronica fights her and forces her to sign the divorce papers.
She continues to have sex with Kevin in an attempt to have a child. She enlists her mother Carol to inject herself with Kevin's sperm.
Veronica spends most of season 4 trying to get pregnant. Her and give initially begin with trying the old fashioned way (through regular sex) however with no avail due to Veronica's PID (Pelvic Inflammatory Disease.) She and her mother, Carol, soon find out that Veronica has an extremely low chance of conceiving (less than 1%.)
Next Veronica and Kev discuss ways on how they could still have a baby with both of their DNAs. In the end, Veronica decides the best way for them to have a baby is for Kev to conceive a baby with Carol since the baby will have Veronica and Kev's DNA both ways and Veronica has no other relatives outside of her mother that could do this safely. At first it start off as strictly business, with Carol shooting Kev's semen into her using a turkey baster, and when that fails they move onto to Kev and Carol having sex with a sheet in between them so that their skin won't touch. However all of the business methods seemingly fail and Kev and Carol wind up having full on sex since a baby is more likely to conceive when the woman has an orgasm. At one point there is a threesome between them all.
In the middle of the season Carol finally gets pregnant however given how many weeks a long she is they find out that she'd gotten pregnant the first time with the turkey baster; this causes Veronica to get upset at her mother because knows that her mother usually experiences pregnancy symptoms early on and she basically continued to have sex with Kev for her own pleasure rather than for the sake of having their child.
Soon after Veronica finds out she's pregnant and with triplets on top of that. This causes her and Kev to freak out because this means they have to financially support four kids, and given that Kev has to deal with the left over financial neglect of The Alibi Room, this leaves them in a very tough spot; so much that Kev starts a "Rub and Tug" in the old upstairs apartment of the bar with the Russian prostitutes that came from the same place as Svetlana worked but got fired because of Mickey's meddling. Veronica, against Kev's wishes, tries to convince her mother to abort her child however her mother refuses and doesn't speak to Veronica for a while after that.
Later on in the season Veronica finds out that one of the triplets got absorbed by one of the other two babies, this winds up being common with multiples as when one infant isn't strong enough they just tend to get absorbed by the others. Initially Kev and Veronica are saddened by this but also relieved because now they only have to take care of three children instead of four.
Carol gives birth to a boy, Dominic however she doesn't want to give him up to Veronica and Kev. Kev is upset at this but Veronica lets him know that he'll still be his son but her mother's responsibility.
In the final episodes of season 4, while Fiona's in prison, Veronica gives birth to twin girls, Amy and Jemma.
In Season 5 Kev and Veronica have difficulties becoming parents. While Kevin is totally thrilled to be a dad, V misses the freedom of being single and desperately wants Kev's attention. They actually go through a break up period of time when they try to live separate lives.
While Svetlana is working at their bar, Kev spills about her immigration status unknowingly to a federal agent. Rather than loose Svetlana, Veronica decides to marry her so she can stay in the US.
Svetlana, Kev, and Veronica enter into the throupple relationship. However, Svetlana's husband from Russia shows up. She lies and said he is her father. She also steals the bar from Kev and Veronica when they thought they were signing adoption papers for their children, they were actually signing over the Alibi bar to the new owner, Svetlana Fisher.
