31 minutes ago, Tramp Graphics said:Boba was a Journeyman Protector, and did use Jaster's name as an alias for a time. The lore did establish his father as being from Concord Dawn, and adopted by the original Mereel. Now, the new canon hasn't gone into Jango's origins prior to AotC, but it does not contradict what had been previously established either. As for the "Cash" argument. No. don't confuse Watts's greed and his species biology, His statement regarding Toydarians being immune to Min Trick is a statement regarding biology. His additional comment regarding money, was his own personal interests. In other words, he is saying "Mind tricks won't work on me, because I'm a Toydarian. Money will work because that has value."
And prior to AotC requiring that retcon, Boba was Jaster Mereel. Then the selfsame sacrosanct lore (in ancillary media) shifted to accommodate the new information that superseded what had come before. And then came a statement that the Fetts weren't Mandalorian at all. Could it be a snobbish reaction of a character that looks down on them? Sure. I don't think anyone has suggested that it can't be. However, it's the only statement on the matter in the primary media that - until the new canon reboot - addressed the matter at all. While the new canon still hasn't supported (or denied) that claim, it's the only claim we have so far. Even prior to shuffling the EU off to Legends, the observable rule was that the ancillary media counted until and unless contradicted on screen...information on screen (big or small) took precedence. The only on-screen information on the matter then or now is a statement that the Fetts aren't Mandalorians.
I'm not confusing anything about Watto. As you so rightly pointed out, he said, "I'm a Toydarian. Mind tricks don't work on me. Only money." If we accept that mind tricks don't work on him because he's Toydarian, with the words that he used, we must also accept that money is the only thing that works on him, also because he's Toydarian. He didn't make the distinction that you claim he did.
Or maybe...just maybe...neither has anything to do with biology. Perhaps Watto sees Toydarians as being universally strong-willed or savvy enough to resist such silly things as mind tricks. It makes as much sense as taking the statement of a single (shady) individual of a species, who's trying to show he holds all the cards in the situation, as universal biological certainty.
