Y/N and Kara have been friends for a very long time. Y/N was also sent to earth to protect Kara and Clark but they were stuck with Kara in the phantom zone. Y/N was placed with other family but was always really close with Kara and Alex. In high school Y/N started to have feeling for Alex but never told anyone. Y/N told Kara 3 weeks ago they are now all working at the DEO.
