Cover art for Serenity Painted Death lyrics by Opeth

To be honest, I'm more to think that Melinda has become a nun. "a harlot of god upon the earth." as said in FOM.

Since she has disgraced her status as a nun to be with the returning protagonist, she has been murdered, our protagonist is captured, and sentenced to death, as in White Cluster.

But different interpretations are always good. :)
