In the Episode I Adventures comics (showing what characters were up to "between scenes" in the movie) Watto hires muggers to threaten Qui-Gon and warn him not to take Anakin off Tatooine. It doesn't work. Qui-Gon: "What happened to your goons was nothing compared with what'll happen to you if I tell the Hutts how you tried to get out of a bet! And so help me, if you don't take care of Shmi Skywalker ..." Watto: "The boy is free! Good riddance to the both of you, for all I care!"
