Tyrion Lannister fled the wrath of his sister.
Tyrion struggles to strengthen and protect the city and family who hate him and refuse to see the peril they are in ; when his father returns , Tyrion becomes vulnerable to the wrath and machinations of the self-serving courtiers who surround Joffrey -- including Tyrion 's own scheming sister Cersei.
Tyrion escapes death again but at great cost , and in fleeing Westeros finds himself in even more danger , but without his Lannister resources.
