OKAY SO THIS MAY SOUND CRAZY BUT HEAR ME OUT.
THE BLUE SPIRIT:
followed aang all the way across the world and was always where aang was, at one point even rescuing him from zhao’s fortress
went to lake laogai to free appa at the same time that the gaang fought the dai li there
has the general height and build of a teenage boy
never uses bending, but instead fights with swords
wears a blue mask
now before you call me crazy, who followed aang around the world, would have a personal stake in finding appa, is a teenage boy who doesn’t bend, knows how to use swords, and has a connection to the color blue??? that’s right—the evidence has been right under our noses the whole time: the blue spirit is obviously sokka.
