Besides Trish being Ally's childhood best friend, Austin is her (future) husband... We have Dez!
Some moments with them:
• Dez and Ally agree that a cloud is shaped like a bunny on a bicycle
• Dez tries to hypnotize Ally so she can get over her stage fright. He ends up hypnotizing himself and falls asleep on Ally's shoulder.
• Dez tells Ally she is his BFF
• Ally was the only one that protected Dez from Trish trying to hurt him with the claw cracker.
• After Ally finished performing with Austin, Dez told her he was proud of her and they hugged.
• Ally was the only one who thought Dez's audition to be Austin's backup dancer was really good.
• Dez asks Ally to hang out with him since Austin's too busy with Kira. When Ally says she has to put the harmonicas away, he keeps asking her if she's done yet, after putting one harmonica away at a time, which means he really wants to hang out with her.
• Dez insults Jimmy after learning that Jimmy didn’t want to give Ally a record deal.
• Dez didn't want Ally to see him cry cause he might have thought he would be embarrassed but it was too late, and then they hugged.
• When Ally said that she was going to join everyone on tour, Dez was really happy.
• Ally was really happy for him that he finally has a girlfriend.
