The next month went by quickly for Lily and Theo. Their mission was done, RITA was dead. The police officers came to question them on Yumi's disappearance, which they denied knowing anything about. Instead, they told the officers about Yumi's fight with Ulrich, and lied telling the cops Ulrich had been the last one to see her before she disappeared.
"It's over." Theo told Lily as they stood on the corner of Lee and Oko wondering where they should go. They couldn't stay, that much was for sure. Sighing, Lily pulled out her phone to check on the affairs going on in their new world. Almost immediately Lily gasped upon finding an article about a band of black ninjas all wearing red R's attacking a hospital, leaving no one alive.
"It is so not over, Theo." Lily shook her head. "We need Yumi." Theo nodded slowly, and went to turn the Lee and Oko portal back on. He reopened the last portal to Lyoko.
Again.
