Even though Ty wanted to merge with the other Ty's from other universes, he missed his brother Dustin.
He still remembered his memories with Dustin, Not only those memories where Ty messed around with Dustin's body, but also those days when Dustin teased Ty before Ty's 15 birthday, and Ty's first transformation attempt, which was on Dustin...
The two headed Ty laid in their bed and slept. While the Ty on the right was asleep, the left Ty stared at the ceiling, thinking about his memories with Dustin, and sobbed "I miss you, Dustin... I don't care if I'm adopted, I wanna have my family back. I want my brother here. I'm sorry about all my mistakes.."
"Hey, no worries, Ty." a voice came into Ty's right ear; the voice was Dustin's, and his right head has turned into Dustin's head.
"Dustin!" Ty exclaimed, still having tears from his eyes.
