Apparently Michael C. Hall and Jennifer Carpenter have split and are filing for divorce.
I wonder how that will affect next season, if it even does. Probably will be alot of tension on set. Which is where that plot of her finding out would have been awesome. That added tension of their troubled relationship translating into the tension of their onscreen relationship, possibly falling apart. Who knows maybe they split up amicably and production doesn't even start until next summer anyways.
