The conflict between Jay Hogart and Rick Murray began in Season 4 of Degrassi: The Next Generation when Rick's return to Degrassi incited student anger after he had put his ex-girlfriend, former Degrassi student Terri MacGregor, in a coma due to his abuse of her. Though not friends with Terri himself, it is likely that Jay tormented Rick since his then-girlfriend Alex Nuñez grew up in an abusive home environment. Ultimately, a prank on Rick by Jay, Alex, and Spinner would drive Rick to bring a gun to school. 

Conflict History

Season 4

In Mercy Street, Alex accuses Emma of being friendly with Rick during an after-school student hangout at The Dot. Emma denies this and proves her dislike of Rick by tripping him when he comes in to attempt to make peace with everyone.

After recovering from his fall, Rick looks up at Emma, enraged. This incites Jay to drag Rick outside and humiliate him before punching him in the stomach. He adds insult to injury by taking off Rick's glasses and crushing them beneath his foot.
