Austin McCann is a troubled kid who was having problems with his mother's new boyfriend. Then Edie, Austin's aunt, catches him trying to break into her house. She lets him stay with her for some time instead of going to Mexico like he was planning to do, since he fought his mother's boyfriend, but she chose her boyfriend over him.
He is instantly attracted to Julie Mayer, and while she is also attracted to him, she doesn't immediately let him know. They spend some time playing cat and mouse, but begin a relationship after both being held hostage by Carolyn Bigsby, much to Susan's displeasure, as she considers him a trouble-maker, and fears he will break her daughter's heart.
In "No Fits, No Fights, No Feuds", Julie gives up her virginity to Austin. Shortly afterwards, it was revealed that Austin had been sleeping with Danielle Van De Kamp, who is also a friend of Julie's. Austin plans to break it off with her to keep Julie from finding out, but it ends with Danielle threatening to reveal their relationship to Julie if Austin quits having sex with her.
Edie Britt and Susan Mayer catch Austin McCann and Danielle Van De Kamp having sex. At the end of the episode, Susan tells Julie about Austin and Danielle and Julie is seen crying on her mother's shoulder. It's suspected that Julie's relationship with Austin is over, as well as Julie and Danielle's friendship. As of the episode "I Remember That", it is established that Julie did dump Austin, as said by Edie to Tom Scavo when Edie broached him about hiring Austin for a job. This was later confirmed by Austin himself who proceeded to get high on the job, telling Lynette his reason was that "Julie dumped me and I'm very upset."
Lynette fired Austin for smoking marijuana on the job, but Tom hired him back because "teenage girls think he's hot...he'll bring in all the high school girls and half the men's chorus."
Later on he discovers that he got Danielle Van De Kamp pregnant just when he managed to mend his relationship with Julie. Orson told Austin he would need to leave town. Although Austin refused, Andrew pointed out that sooner or later he would just hurt Julie again. Austin agreed to leave; said goodbye to Julie and told her she was the only person who ever gave him a second chance, and then rode away on his motorcycle for parts unknown, never to be seen again.
