Cairax has better pain tolerance, but is still vulnerable to the Ex virus

“What? Oh. Very observant of you, my little doctor. It doesn’t seem to have healed at all, does it? I feel better, but the sensations in this body are always so muddled. No … no, there they are. The tiny things are still there, chewing away, weaving themselves into my blood and muscle.
Oh, perhaps. However, in retrospect, I think I shall remain in this skin. If there is any chance for me to survive, it will be in this form, yes? As Maxwell I had an hour or so left, less if you decided to conserve any more resources. No, I believe Cairax has a far better chance of fighting off the infection … or any of the dangers that apparently come with it.”
