S1·E1 Evie's Thirteenth Birthday

After thirteen years of keeping Evie's identity from her, Donna is forced to reveal the truth at her thirteenth birthday party when Evie exhibits a special, alien power that enables her to freeze time. Evie learns she's half alien and that her father is from the planet Antareus--not a CIA agent as her mother has been telling her all along. She is given her father's gift of the cube, a genetic device which allows her to speak to her father on Antareus. Although anyone can hear her father over the cube, her father can only hear Evie.
