Johnson got something called "Boren's syndrome" from overexposure to plasma grenades. Or at least something along those lines. Anyway, that somehow altered one of his genes, causing him to be different enough from normal humans so that he isn't infectable by the flood. They basically hijack the nervous system and they weren't able to do that with him. As for escaping halo, the Clones and Lies (i think thats what it's called) has a theory on that. But I haven't the foggiest.
