^ See, that's where the contradictions come into play. "Stigma" makes it pretty clear that P'nar syndrome is universally known, feared and reviled, but how could that possibly be the case if melding is a forgotten technique? Which is itself a totally absurd idea, come to think of it.
So really, I guess I'm saying that both
"Fusion" and "Stigma", while well-written and compelling eps on their own terms, should be considered non-canon.
