Piggy.

Piggy started having mixed emotions when she starts seeing that Kermit is always with Denise and not her. she also thinks about the death of her father and how her sisters blamed her for it. She also has to deal with the death of her and Kermit's daughter. (Which he struggles with too) so basically Piggy has mixed emotions about a lot of things and Kermit has some upsetting things with the fact that his daughter is dead.
