Reiko Aylesworth will return early in the season as Malia, Chin’s ex. I hear the pair might be considering a reconciliation, but Malia’s bad blood with Kono will definitely be an obstacle.
I was discussing this with @lankyguy and @NurseBrak today on twitter… We all agreed that Kono is deservedly upset for Chin keeping her in the dark about their Uncle’s problems. But her perception of Malia is probably unwarranted since Chin allowed everyone to think that Malia left *him*. In any case, season 2 should develop Kono and Chin’s story lines significantly.
