- “There's nothing more noble or free than the heart of a horse.”
- —Davin to Beth[src]
Davin was Beth and Tom's coworker at St. Equis Hospital. Davin was in love with Beth and he constantly hit on her and tried to seduce her. Because of this, Jerry (his colleague Beth's husband) was extremely jealous of him, despite the woman denying having any feelings for him.
In the Pilot, Davin was seen working with his colleagues Beth and Tom on saving a horse's life. He later comes back and interrupts husband and wife's fight, telling Beth how they did a very beautiful and passionate thing together, saving that horse's life like that. It's obvious that Davin was hitting on her, and trying to swoon her over, with the way he was being so poetic with her. In response to this, Jerry slams the door shut and says "Since we're fighting, if you ever have an affair with that guy I will come to the hotel room and blow my brains out all over your naked bodies."
In "Rick Potion No. 9", Beth is called into work late at night by Davin and Tom to help him after a horse racing track had a starlight derby where there was a "seven-horse collision". After Beth and Davin save the horses Davin tries to seduce the woman. After sneezing, Davin becomes afflicted with the "Morty love potion" where he becomes obsessed with Morty (his colleague Beth's son). Beth then runs away from Davin when the man turns into one of the "Mantis-people" as a result of Rick's initial cure for the Morty love potion. Jerry bursts in the door and beats Davin to death with a crowbar, saving his wife's life.
It is assumed that the version of Davin who live in the Replacement dimension is still alive, since the originals Rick and Morty of this Dimension have overturned the disaster, even though the man has never been seen or mentioned again.
Davin was a tall and muscular man with very tanned skin and a sculpted face. He had blond hair and a rugged beard of stubble on his face. He was usually seen wearing his work clothes, being a set of light blue scrubs, a white apron, and a surgical mask.
- It has been confirmed by the Rick and Morty assistant, Tamara Henderson, on her Tumblr, that Brad and Davin, while presumably being written off the show due to their long absence after Season 1, will return in Season 3 of the show.
