Hmm, I think that some roumors about the wars with the clones are not right, Look up the source for your information and u will find out sooner or later that the clone war started a long time ago.
The interesting part is that the clones of Björn are not looking a lot like him, This is not a big problem because there is only a few people that have meet him in real life, some people think thay have meet him but that is just clones. u cant go out on the streets with a baby on your back, right?
