Kod Lyoko Sezon 2 Odcinek 8: Missing Link

In an attempt to save Aelita from the Scyphozoa, Yumi finds herself engaged in a brutal combat against the monster. Shortly afterwards, Jeremy sees that, as a result of the combat, Yumi can no longer be devirtualized. In fact, it looks like a vital part of her is missing -- her virtual DNA code! How can he get it back to her? After numerous attempts at finding a solution, our heroes realize that the only way to help Yumi is to go inside of XANA and look for the "missing link" -- in Sector 5... danger ahead!
