Liam is first seen as Lightning Dexter's jockey, but is soon fired after performing illegal activity with one of Lisa's horses.
Season 3[]
Liam meets Ty after he starts working at the racetrack. He greets him by giving him a handshake with a buzzer to chock him, claiming it's only an initiation. He tries to ride Lightning Dexter but when he spooks at the gate he rears up causing Liam to fall off. Later, he and Lisa watch Amy ride him after Tim buys Dexter from Lisa. The next day, Amy tries to find Lisa at the Fairfield trailer only to be greeted by Liam. She tells him how her phone vibrated and Dexter spooked and asked if anything similar had happened with him. He relents in telling her that he never has his phone when he rides. After Amy realises that he's been buzzing Dexter to get him out of the gate faster, she and Ty go back to the trailer to look for evidence when they find no one there, only to be found by Liam. Lisa comes in and asks them what they're doing but due to a lack of evidence Lisa doesn't believe her. After Jack talks to Lisa, she goes investigating and confronts Liam at the track with buzzers she found in his locker at Fairfield. She fires him and he starts lashing out that she's using him as a scapegoat. (The Starting Gate)
