"You're one of the good ones, Dallas."
Their friendship began when Dallas saved Alli from humiliation after Dave Turner left her alone on their date. Alli told Dallas all about her problems, and he readily listened to her. He decided to take her out to have some fun, and in return, she gave him a ticket to a Jay-Z concert, which did not go over well with Alli's best friend, Clare Edwards. Meanwhile, Alli was planning on graduating a year ahead of her classmates, and was overloaded with schoolwork. To help her stay awake and focused on her studies, Dallas gave her a bottle of uppers. As a result of the tension between her and Clare, as well as the stress from school, Alli proceeded to freak out due to lack of sleep and the pills Dallas had given her. Once Dallas apologized to Clare, he and Alli were free to go to the concert together. However, as Alli was driving herself and Dallas to the concert, she fell asleep at the wheel, causing a car accident.
Dallas and Alli continued to grow closer, but Dallas decided to put off a relationship with her in order to focus on his son, Rock Dallas.

She later goes over to his house in the middle of the night to get the ticket, and he tells her that she is acting like a crazy person.

When Alli leaves to yell at Dave, Dallas tells her that no one is there, and Alli realizes that she had been hallucinating. Dallas runs all over looking for her, and finds her in her car. He tells her she isn't probably hallucinating because of the pills, but because she isn't sleeping. Alli freaks out that she might have messed up her brain and throws away the pills.
