The sudden weight loss definitely "appears" to be due to illness (...or God forbid: substance abuse). For me, Forest is just one of those brothers that looks better with a little extra weight. But his eye, in my humble opinion, is part of his character (...and appeal), and actually draws me into him. Besides, there's nothing that could be done for that short of plastic surgery, and that could have a potentially adverse effect.
