The two had a good time, but unlike Paris, Tristan only thought of her as a friend.
At Madeline's party, Tristan got into a fight with Summer.
Summer and a Chilton student named Austin were locked in a bathroom together, making Tristan suspicious and angry.
He tried to talk to her, but she was concentrated on partying with other guys.
Eventually, he got her to talk to him, but that unfortunately caused her to break up with him.
Tristan told Rory that he wanted to take Rory to the dance but she didn't believe him, since he is mean to her.
He watches Dean kiss Rory and is obviously jealous but swats it off to go make out with his date. At the end of the episode, Dean tells Rory that Tristan has a thing for her.
Tristan was briefly depressed and humiliated by the breakup, which caused him to sulk alone in Madeline's piano room. Paris consistently admired Tristan and dreamed that he would ask her on a date.
Rory suggested that he date someone with "a little more substance", after his breakup with Summer. Paris mentioned to Rory that he kissed her goodnight, making her think that he wanted to date more.
Tristan gave Rory a lot of attention, angering Paris because she herself had a crush on him.
This made the tension between Rory and Paris on many occasions.
Paris and Tristan have been in the same classes since kindergarten, and he kissed her, on a dare, in sixth grade.
