Whoof. That’s one of the dumbest theories I’ve ever heard.
Let’s deconstruct it like I did with the equally-spurious “Rey is Palpatine’s Granddaughter” theory!
Similarities to Anastasia aside, Rey being Han and Leia’s daughter is goofy as far as I’m concerned. Makes no sense to me that Han and Leia would be so heartless as to just dump Rey on a planet alone. That’s messed up. And then when she shows up in their lives, they don’t bat an eye? Nah. Not buying it. Sure, maybe she was kidnapped or something and sold into slavery, but I just don’t see her as being a Solo because there’s literally no reaction or exposition about it.
The way the original theory keeps saying that they’re alluding to Rey (by saying “it”? What?) in the film and that “It could mean Ben, but IT DOESN’T!” Of course the tragedy is Ben’s fall to the dark side. There’s no reason to believe otherwise.
The part where the guy goes on about Boba “witnessing that Vader had a son” didn’t happen. Boba doesn’t know Vader is Anakin, Boba doesn’t know Anakin had a son, the only thing Boba learned about Luke in their tussle in the comics is Luke’s name, and he feels it’s not very helpful information an then he leaves because Vader doesn’t say anything. He isn’t there when Vader reacts. So that’s nothing.
The next part just… what? “Mandaloren” What? How high was this person when they came up with this shit? Mandaloren armor? Just… you’re embarrassing yourself, dude. I don’t even need to say how stupid this is. Also, they use the term “Mandalorian” in The Clone Wars and Rebels, so…
The First Order part implies that there was at one point a “Mandaloren” (god that’s stupid) power in the galaxy that we’ve never heard of. Nope. Plus, in this canon, what connection does Boba have to the Mandalorians? His father, sure, but he doesn’t seem to have any connection to them in The Clone Wars.
“Not human but humanoid” meaning that he’s a clone is technically correct but very much a reach. Not buying it.
The rest of it is meaningless. So Snoke knows who Han Solo and the Millennium Falcon is, he was only the Rebel hero who helped destroy two Death Stars and end the Empire. Even Rey knows the legends. It’s all just guff. Not to mention Boba Fett is a bounty hunter and why would he suddenly become a space wizard emperor to get back at Han? One of the most spurious theories I’ve ever heard. Can’t wait to see it not happen in the theaters.
