Plot summary
Paige's Thanksgiving dinner for the team is put on hold when her estranged con-artist mother Veronica ( Lea Thompson ), posing as a real estate investor, enlists Scorpion's help after she accidentally discovers a forgotten radioactive nuclear reactor that is about to explode in an abandoned building. In addition, she is being hunted by shady businessmen who want their money back. Wanting to save his beloved Warlock's Chest comic book store from demolition, Sly starts a petition and decides to run for town alderman. Meanwhile, Cabe becomes interested in Allie Jones ( Reiko Aylesworth ), the competition's campaign manager. Later, Veronica, after reading Walter's good intentions, declares that he is what is best for her daughter, not Tim – and that she will help him get her back.
