Wrong Exposure (S04E25)
Aelita comes across a picture of herself with Franz Hopper at the Hermitage, featuring a mathematical equation in the background. Jeremie realizes that the program functions as a reset tool for Lyoko, which, while not particularly groundbreaking, could still be handy. Meanwhile, Odd tries to impress a girl in his photography class but accidentally sends the picture to Sissi, who shows it to her father. He questions the group, and Jeremie notes that if Aelita were the girl in the photo, she would be twenty-four now. Jim punishes them with detention in the library before anything further can be discussed. Just then, Jean-Pierre, under XANA's influence, captures Aelita and transports her to Lyoko, where the Scyphozoa awaits. It tries to take control of her and lead her into the digital sea, but Ulrich and Yumi intervene just in time.
