Aelita is slowly adjusting to life on Earth with the rest of the Lyoko Warriors, but not without difficulty. Meanwhile, Jeremie and the others are busy investigating the mysterious house in the forest, The Hermitage, and its owner - who turns out to be an ex-professor at Kadic Academy, Franz Hopper. After Aelita is scorned by Sissi she runs away to Lyoko and seemingly disappears off of the radar; only to be discovered in a brand new sector, Carthage.
