You worked for Tuco, and when he and Mr. White and Jesse agreed to trade for the meth the male duo cooked, you met him. When Tuco died, you wanted revenge. You knew it was them, but as fate would have it, you ended up partnering with the pair of men. They had protection and contacts because of who you were, and you got the profits for yourself. But you and Jesse developed a bond, a friendship that you valued from the bottom of your heart.
