Well, the base of the plan is a seller, who recognizes Joseph, and also knows Alexi's taste, will want to show a very untamed slave(Haven't picked the race yet, but if you want a hand in that, I am open to suggestions. I only ask that it at least has a mostly human form, even if it's natural form is not humanoid, like Elaria.) so any point before actually meeting the slave works. I have a few ideas for the slave myself, if you would like to hear them, I can list them here if you like :P
