|35px Kadic Bombshell is too short. You can help Code: WIKI by expanding it.|
When Sissi's friend from Iceland, Brynja, arrives at the school, all the boys swoon over her, making Sissi envious. When Brynja takes an interest in Odd, he ends up showing her the supercomputer. While there, she messes with it despite Odd's pleas not to, causing a glitch in the virtualization program that causes every virtualization to happen in the wrong sector, and materializations lead to different sectors instead of the Scanners. This becomes all the more problematic when William catches Aelita alone on Lyoko. When forced to choose between his friends and his new love interest, Odd initially stays with her, but decides that his friends are more important. After rescuing Aelita from William, they make up. Brynja leaves soon after, so they have no need to perform a return trip.
