There is only one Alice and one Bob
in every world that I am talking about too, but there are 4
different worlds, and in each world they observe 4 unique particles;
and 4 different yous are observing the
4 different
Alice and Bobs. The only way to know which of the yous is you is to
observe Alice and Bob observe their particles.
They can talk about their results in their own worlds. So what?

You appear to have a clear grasp of the situation -- either QM is
intrinsically non-local, or we have magic......
Or non-realism.
If by non-realism you mean some version of Einstein's "elements of
reality", then this implies non-locality (a Bohmian-style model).

And before the second half of the 20th century most physics would say
non-locality WAS magic and non-reality was even more
disreputable
, but today we know from experiment that like it or not that's just
the way things are.
