Smallville :

Lionel arranges to have Clark kidnapped using kryptonite tazers to subdue him and held in a kryptonite-lined cell at a LuthorCorp facility. After Chloe and Lana find a military electric probe at the farm, they confront Lionel, who throws suspicion onto Lex. Chloe and Lana take Kara to the Fortress and beg Jor-El to restore Kara's memory, as she is the only one who can save Clark.

Patricia Swann, Dr. Virgil Swann's daughter, comes looking for the 'Last Son of Krypton' and accuses Lionel of taking the 'Last Son' for himself, and having a hand in the deaths of her father, the Teagues and the Queens – three families who came together with Lionel, under a secret societal name of Veritas, to welcome the 'Last Son' to Earth.
