Xana died. Team Ben 10 and the Lyoko warriors finally have their victory. They all celebrated at their mansion. They are all happy. Years it took them to finally end their greatest enemy. Not just Xana, their other enemies have been defeated: Tyron, the Marabounta, Vilgax, Malware, Eon, Maltruant, Dark Ulrich, Aggregor, the Highbreed, other dangerous foes. The rest of the foes are still dwelling in the world. Eventually they will be found. For now, they celebrate.

They should be more happy than ever, specially Aelita, Ben and Ulrich. Ulrich, Aelita and Ben 10 have discovered they are siblings thanks to Aelita regaining all her memories. It's good because despite the disappearance of their oldest sister and the presumed deaths of their parents, they at least have each other.

Two brothers, Aelita thought. That would make her the second oldest. But she is physically younger than Ulrich and Ben. Nevertheless, she is mentally older than both her brothers. Aelita once lived as an adult body, but her body shrunk and in the process she lost her memories. It didn't last forever as the long war with Xana benefitted Aelita to regain lost memories. She hasn't thought about fixing her size yet.

"How does it feel to have two brothers?"

Aelita turned. Gwen was next to her.

"Hope.", Aelita answered as he watches Ben and Ulrich sparring for fun. She smiled when she saw Ulrich gets floored by Ben. She found it amusing to see Lyoko warriors' greatest fighter beaten by someone who is slightly less experienced than Ulrich.

Gwen was amused too at Ulrich's defeat. "What's next for you now that your memories have been restored?".

Aelita's smile faded. She lowered her head. "Gwen, my true quest begins in out of this planet.", she said.

"Nothing I can do to stop you, huh?", Gwen said.

"I won't be gone forever. Just promise me you will take care of Ulrich and Ben."

Gwen places her hand over Aelita's. "I promise.", Gwen vows to watch the boys.

Odd came with his arms wrapped around William and Kevin. "What are you ladies doing? It's party time!".

"Yeah, what he said.", Kevin said.

While everyone is enjoying the party, an old hermit watches from far away. He observes Ulrich, Aelita and Ben, the three children of an old friend he once lost. He senses a time will occur when a bad event will cause their lives to change. Though he hopes the nightmarish event won't kill them.
