Their relationship is kinda confusing on both sides. Jake's fond of (loves) the kid and finds himself looking out for Beau a lot. Which annoys him.

Beau meanwhile very much loves his Uncle Jake, but he's well aware he's not a nice man. Rico's told him to be careful, and Jude has too, though he has told Beau Jake won't kill him.

idk this world and Jake are Merlin's I'm just playing around
