buddies

Jax calls him Davin 50% of the time. (He intends to say Gavin, it just comes out as Davin)

The other half of the time?

"Buddy"

they are cousins but Jax doesn't really seem to care to hear about the family tree.
Buddy is good enough for him.

they make me think of the Fox and the Hound... such good friends... and SO CUTE when they call each other "Buddy"
