 * The Blessing couldn't distinguish between him and Jack, so gave them both "the fixed point immortality".
 * The Blessing had to operate symmetrically.
 * The Blessing gave Rex immortality as a gift.
 * Rex became mortal before the negation of the miracle (possibly due to having Jack's blood in his veins) so when the miracle was negated the "cross-wires effect" mentioned in episode 2 occurred.
 * Could Bad Wolf be involved?
