I've actually got Mother Skywalker (Carima) as bit of comedy relief, adding some light humor to the story. She's an impulsive, quick talking, feisty yin to Anakin's slower, more thoughtful, restrained yang. They're friends and coworkers on Tatooine and she manages to talk her way into coming with him when Skywalker leaves with Kenobi. They start falling for each other over the course of Episode I, get serious and committed in Episode II, and sadly lose each other in Episode III.
Really she's there to keep Anakin grounded and in a sense act as the more everyday person when he starts becoming a serious Jedi. There's a bit of Grant/Hepburn dynamic with the two of them, with both driven a little crazy by the other, but also deeply appreciate of those very qualities. She's his connection to his humanity more than even Obi-Wan is, and once he loses that, he falls hard.
