Having it fit together in a time travel narrative is charity to the clique of extremely anal canon-wonks
Which is charity that is totally unnecessary. See my previous post.
For example, I'm a huge fan of original Battlestar Galactica
. Did I complain that nuBSG wiped it out? Of course not, because it didn't. The two versions can and do coexist, in parallel realities. Nothing is ever wiped out.
