They find him locked in a storage room, where the four reveal that they do love him, and that a special someone will come his way sooner rather than later. Still shaky about having his first kiss be on stage, Tori kisses Tristan, and the two make it to the show at the last second.In I Want It That Way (2), Owen is surprised to see Tristan in the weight room and that Tristan lost 7 pound from his diet. Owen tells him that losing weight that way is dangerous, and says to lose weight, he needs to do it the right way through eating right and exercise. The two proceed to work out on machines next to one another. Later, Tristan is in the hospital after having a minor heart attack, and he asks Owen if he is going to die. Owen asks him why he would do this to himself, and offers to help him set up a proper work out plan.
