Face of the Band: Cherie and Joan. The former due to Kim pulling strings to give off this "vibe" (to Cherie's anger), and the latter due to her solo career.
Woobie: Every member, considering they had to deal with Kim's often abusive treatment of them.
Cherie in particular. The poor girl had to deal with two sexual assaults, her parents' divorce, both her solo albums being complete flops, a failed acting career, and drug addiction...all before she turned 25.
