This topic has been discussed before, so you might be interested in the archived discussion at Howling:Rex is Immortal. --89.241.211.213talk to me 09:57, March 12, 2014 (UTC)

 * 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?

The Bad Wolf entity certainly could be involved. Although, as far as Rose was concerned, she was the Bad Wolf only briefly, she had access to all of time & space, so her effects could show up anywhere & at any time. That, by the way, applies to The Day of the Doctor, too: the real Bad Wolf could have been influencing events, rather than it only being the Moment taking the appearance of Rose/Bad Wolf.

In both cases (& probably others I've not thought of), the question isn't whether or not it's possible that the Bad Wolf was involved; it'll almost always be possible. The question is whether or not the Bad Wolf actually was involved. In The Day of the Doctor, the motivation would fit -- saving the Doctor (again). In the case of Rex, though, there's no very clear motivation for the Bad Wolf to give him the same immortality as Jack.

Also, we don't really know Rex does have the same immortality as Jack. We only know he revived once. If we find out from future episodes of Torchwood or Doctor Who that he's revived repeatedly, that'll be a different matter.

Incidentally, there's been a lot of comment about how Miracle Day established that there was nothing special about Jack's blood. It didn't. All it established was that there was nothing special that anyone could find. It could simply be that nobody used -- possibly nobody had -- the right technology to detect the differences. (Before about the start of the 20th century, nobody knew about differences in blood group. As a result, it was a mystery why transfusions sometimes worked but often didn't.) --89.241.208.10talk to me 21:50, March 16, 2014 (UTC)
