Most personal pronouns do not distinguish between dependent and independent forms, but here is a dependent subject pronoun in the 3SG (i, contrasting with independent pronoun li). If one takes the phonetically more often than not reduced form l (full form li, 3SG object pronoun) as a form in its own right, then we have value 4.
