The Walker family first learned of Rebecca's existence while attempting to crack the password to a locked account which contained funds that William Walker had embezzled from Ojai Foods. Holly initially denied that Rebecca was William's daughter, revealing the truth only after the account was unlocked with the password "S-K-T-K-J-R" (the initials of the five Walker children, plus R for Rebecca.) Sarah, Tommy and Kevin, the three Walker siblings involved in the family business, initially agreed to keep Rebecca's existence a secret from the rest of the Walker family, although Saul eventually told Nora about Rebecca.
