Watto could never remember why he had come to Tatooine of all places.
He prepared to leave Tatooine several times, but was always drawn back to the races.
He would sell anything and everything, including information
Watto used all of Ani's talents, including the ability to persuade stubborn customers with just a wave of his hand.
Years afterward he would lament the day that man walked in looking for Nubian parts.
Watto was sure the other man had cheated, (those were his lucky dice!) but everyone did so he didn't have a chance of getting him for it.
He lost both Skywalkers and his only comfort was that he had sent them off with good masters.
When Ani came back years later he was to busy trying to turn the situation to his own advantage to be to frightened even though something told him that the little boy he knew was on the verge of becoming a dangerous predator.
For years after the Clone Wars people came to him asking if he knew where little Ani was and he sent them all away with curses.
All except for one old man named Ben who didn't ask for that, but rather for a copy of the hologram taken after The Race. He noticed the man's eyes lingered on the Jedi (he had figured it out) instead of Ani but he didn't say a word and never told a soul.
