So all the stuff about Ned’s & Cat’s baby names has me wondering, why would Tywin give Tyrion such a Lannister-type name. Maybe it’s just me, but it sounds much more “lordly” than the mundane Jaime.

turtle-paced:

The World of Ice and Fire covers this.

A later monarch, Tyrion II, was known as the Tormentor. Though a strong king, famed for prowess with his battle-axe, his true delight was torture, and it was whispered of him that he desired no woman unless he first made her bleed.

Surprise surprise, Tywin named Tyrion intending to hurt.

Tywin for best dad.
