You know, the wife in the concept of Seventh Wonder's third album, Mercy Falls, is a complete and utter scumbag.
She has an affair, gets pregnant by the guy she was having an affair with, doesn't tell anyone until confessing to her husband as he's driving home years later, causing a horrific car crash that puts him in the coma that the majority of the story takes place in. Then, later, her son tries to donate bone marrow and it's rejected by the man because it's not his child. All the while, she drinks herself into a stupor.
In other words, she KNEW the treatment wouldn't work because her son wasn't HIS son, yet she let her son go through the process of trying to donate to save the life of the man that he thought was his dad ("Tears for a Father" takes an even more tragic note after that knowledge:

She didn't tell him that he was born from the affair, and then after the treatment is rejected, she just gives up and lets her husband fade away thus causing her son to lose his father (even if not by blood) while pretending that she actually loved her husband.
I never made that realization until now... a very underrated concept album, to be sure!
