Katie Finneran plays Jaye's sister Sharon, the oldest of the Tyler siblings. Sharon is a successful and ambitious immigration attorney, and ends up being an unwilling participant in many of Jaye's schemes, particularly those that involve legal counsel. Sharon appears to be everything that Jaye isn't: goal- and career-oriented, the recipient of their parents' approval, extremely high-strung, and with very little enjoyment in life. Sharon has a secret, though, which Jaye discovers in Episode 1, Wax Lion: Sharon is a closet lesbian. The secret ends up drawing Jaye and Sharon closer.
