I think Blendin Brandon is futare Dipper becausss

A: we dont know his real name, only his nickname Dipper.

B: Blendin got fire on his head (probs why he got bald) and Dipper got fire on his head when he time traveled and thats how he got bald to end up as Blendin.

and C: I think Blendin was extra annoyed about dipper getting the time travel thing caus of the whole Mable theory and that in the future he probs found out about mable learning the tim travel machine and then something happened that broke thier friendship. Also, that might also explain why mable isn't with blendin (might-be-dipper) in the future.
