Adam and Dave started off as rivals when they were both vying for the chance to host a Degrassi radio show geared towards the male population of Degrassi. Dave did not agree with Adam being given an opportunity to host a show for boys, as he was not born male. This led to animosity between him and Adam. After Dave learned about Adam's experiences as a young trans man, they were eventually able to put aside their differences, and work together as friends and co-hosts on Degrassi's radio show, "Mano-A-Mano.". The boys developed a close friendship, often confiding their life and relationship problems in each other, often resulting in the other asking vague yet relevant questions about the others situation on-air, and requesting feedback from their fans. They remained close until Adam's death in Season 13. Dave is seen at Adam's funeral, along with all of their mutual friends.
