This episode was both exciting and suspenseful. Along with learning more about Aelita and her father, Jeremy makes a new program that can restart the super computer. Jeremy manages to create this program by using a code written on a chalkboard in a picture of Aelita and her father. This program comes in handy at the end of the episode when XANA uses the Scyphozoa to brainwash Aelita so she will throw herself into the digital sea. When the gang can't figure out how to save her, they use the program. It was actually pretty cool how the program worked: the sound effects and colors were awesome! My favorite scenes of this episode include: the sword fight between XANA-Aelita and Ulrich, the scene where Yumi yells at Ulrich because he knew a lot about the girl Odd liked, and the scene where the kids attack Jim because he won't let them leave the library to save Aelita.
