Tragedy/Rebirth The protagonist is a hero with one major character flaw or great mistake which is ultimately their undoing. Their unfortunate end evokes pity at their folly and the fall of a fundamentally 'good' character.
During the course of the story, an important event forces the main character to change their ways, often making them a better person.

And what doesn't kill a Murphy makes them stronger - or at least that's what he tells people is on the Murphy coat of arms. And no, the sigil is not Kiernan's flexing biceps.
