IMO, Turalyon cons green to Alliance, red to Horde; Alleria cons neutral to both, because her primary agenda is Thalassian independence, disentangling from the Horde. Not "GARRR I must now kill my own people!" which would be a) completely derivative of Vereesa and b) completely asinine... also like Vereesa, who has that covered, and from whom the audience expects less than from Alleria, who isn't the baby, she's the oldest. Her nature will be to fix the proverbial family, maybe the literal one as well.
By necessity, Turalyon might be red to Horde the way that Vereesa is in WOTLK Dalaran, non-aggro, just depends on where they would be in game and doing what.
