Bo freaked Getty out a lot when the two first met. To be fair, they had just died and woken up in Limbo, only to be immediately met by a goat-headed dude who spilled hot coffee on them. Getty warmed up to him, though, and currently views him as a sort of younger brother who needs to be protected.
Bo immediately latched onto Getty - they were the first soul to ever show up in his part of Limbo! He was probably a little too excited about that. Bo calls Getty his best friend and is willing to bend - or even break - the rules of his job to resurrect them.
