Taking in Kara
When Superman discovered his cousin Kara Zor-El, he and his wife took her into their home. He asked Alex to be a sister to Kara.

Kara was enrolled at Midvale Junior High School along with Alex. Kara was freaked out by her new world along with her developing powers. When they went to the beach, she embarrassed Alex by staring at the birds as they did not have them on Krypton. When a car crashed close by Kara ran to the rescue saving a mother and her child. However, Alex was injured by a car door when it exploded. Jeremiah spoke with Kara telling her that Alex was fine and it was just a few stitches. After that Kara decided to hide her powers telling her that they already have a Superman just be herself. He gave her a pair of lead lined glasses to help her control her visual powers.

Joining the D.E.O.
One evening Eliza went outside to the porch to get her husband Jeremiah to keep her company while she worked on her dissertation. On the roof, Kara convinced Alex to sneak out and go flying with her, despite the latter's initial protests. While holding onto Kara as she flew, Alex told her that it was amazing. Kara and Alex were caught sneaking in by Eliza and Jeremiah, and lectured about the rules. After someone knocked on the door, the girls were sent up to their room, with Eliza telling Kara not to use her super hearing to listen in on their conversation. Answering the door, Hank Henshaw along with two associates requested to speak with the two. They gave him an ultimatum: work for the D.E.O. or they would take Kara into custody
