Trinity appears irregularly and she is portrayed as being a sometimes troubled child who is allowed to misbehave when it suits her. She seems to be given minimal, if any, discipline and this allows her the freedom to do as she wishes with no concept of consequences.
Throughout the show she gets into all sorts of situations: she becomes a bottle kid, steals tires from cars, drives her father’s friend’s car (and is subsequently arrested for this) and becomes addicted to cigarettes. All of this is as a result of Ricky's influence and example. Lucy's standpoint on this general behavior is unclear, but in each instance, she blames Ricky, who maintains that getting into trouble will teach her valuable life lessons.
Trinity loves her father ambivalently, sometimes looking to him as a role model and other times echoing her mother's sentiments that he is a loser.
Trinity's age is really never made clear, as most, if not all, references to it have come from Ricky, who cannot seem to remember her actual age. ("Take Your Little Gun And Get Out Of My Trailer Park") In a testimonial by Ricky, it is indicated that Trinity has already celebrated her seventh or eighth birthday and not seen Ricky since as of the start of the series. ("Take Your Little Gun And Get Out Of My Trailer Park") However, in the early third season, Ricky indicates that Corey was being ridiculous for physically fighting a nine-year-old (Trinity) and likely to lose either because Ricky would intervene or Trinity would win anyway ("If I Can't Smoke And Swear, I'm Fucked") . With this, the third season seems to be about two to three years after the first season, allowing for the boys jail time, which was at least 18 months between seasons 1 and 2. Further still, Trinity seems to be around three to five years old as of Christmas 1997 (allowing for the typical discontinuity found within the series and the special), indicating that Trinity is, in fact at least two or three years older than Ricky has indicated. ("Dear Santa Claus, Go Fuck Yourself").
It remains unclear whether Trinity's biological father is Ricky or another character, such as Julian. See S1E1 for evidence.
In the 2014 film Don't Legalize It, Trinity appears to be around 16-20 years old, for Trinity can legally drive Ricky's car.
Life Following Season 8
In the beginning of Season 8, Trinity is shown to be working at Julian's Sports Bar and Gym, as seen in "Money,"Money Can Suck My Cock". She lives with her mother Lucy where they stay at George Green's house, and during this time Lucy and George are dating.
In Season 8 Episode 3 "The Dirty Dancer", Trinity announces to Julian that she is pregnant. Later on in the Episode, Trinity announces to Ricky that she is dating Jacob Collins and is pregnant with his child. Ricky is not happy that Jacob is the father and threatens him and gives him a hard time throughout the remainder of Season 8 while Trinity is caught in the middle of their feud.
In Season 9 Episode 3 "Anointed In Liquor" Trinity gives birth in a barn to a baby boy that they named "Baby Ray". But due to Jacob messing up on the birth certificate application, the babies name is revealed to actually be "The Motel".
In Season 9 Episode 10 "The Liquor Snurf" Jacob purchases a ring from "Eons" and asks Ricky to propose to Trinity for him before getting arrested. Trinity says yes, and they have stated in the Episode that they are planning a wedding with Cory to be the best man.
In the 2006 movie, Trinity was played by Lydia Lawson-Baird, and not Jeanna Harrison as in the series, though Harrison has returned for Season 8 and the rest of the series including the animated series.
