Forgot about 9 and 10 and watched them this weekend. Great finish. I havent read the manga in a while, but I think Alucard explained about Schrödinger and that it took 30 years to kill off all 3+ million other souls in his body so only Schrödinger was left and with that, he was able to regain his self conscious, thus allowing Alucard to live again. Also since he is able to draw upon their powers, I would venture to guess that Alucard is truly immortal now with Schrödinger inside of him.
