I suspect you wrong him here—I’m guessing post-freeze Mitchell would say “Obviously I feel like I’m the same person, but now I know I’ve been cryopreserved I must conclude I’m a copy, not the real thing. I feel good about being alive, but it’s copy-Mitchell who feels good, not the guy who got frozen.”
Actually, there is. If we cryopreserved Mitchell and then reanimated him, he would be very surprised: it would falsify his theory.
If we did it to anyone else, however, that wouldn’t be enough. It would have to be him.

Well, in that case he really has joined the fairy cult.
