For the record, I'm hinting at going dark for the same reason I order my steak "medium", when what I really want is "medium-well." BC's tendency has been to err strongly on the side of over-pursuing, so I took that into consideration.
If advocating darkness leads to some dimness, I think it would be good, as some dimness is in order -- for his own self-preservation, and also for his wife to have time to consider -- and feel -- the consequences of her poor decisions.
I do not think he should be overly supportive emotionally.
