Not gonna lie, I'd actually be interested in seeing a CaW representation of autoimmune diseases, considering how brutal it can get, with what we're used to as "the good guys" becoming so obsessed and corrupted with their job, that they end up hurting and, eventually, killing others, thinking that it's the right thing to do. Although, if I remember correctly, autoimmune diseases aren't really curable right now(?), so I guess it wouldn't be a very long story. Maybe a long one-off? Or a short series? I dunno, but seems like a cool idea.
