Please, is entanglement swapping "understood" in the most famous QM interpretations?

To me, it seems that any of the interpretations really helps much...

Even more: I guess this event would even show that those interpretations are wrong.

But of course I'm wrong, I'm just putting my view to see if anyone can help me understand where I'm wrong...

I mean, for example, lets take a 4 photons experiment, and photon 1 and 4 are entangled if photon 2 and 3 are projected into bell state:

Copenhagen:

The wave function of the first foton collapsed as it was detected and... somehow... if photon 2 and 3 got projected into bell states, it will show that it was collapsed in a way that shows that photon 1 and 4 are entangled.

(How did the wave that collapsed in the detector 1 got influenced by photon 3 and 2 being projected into bell states?)

Many worlds:

Photon 1 is travelling is it's wave function... it interacts with it's detector and the universe unfolds into many universe, one for each probability of detection... photon 2 and 3 got projected into bell states and... somehow... out of an infinite numbers of universes, ours is the one that have the photon 1 and 4 in bell states.

(Are we just that lucky that we are in the universe that, by blind chance, collapsed all the waves "just right" to all photons 1 be entangled with photon 4?)

De broigle pilot wave: our photon 1 is being carried by a pilot wave... and it hits it's detector... and if photon 2 and 3 are projected into bell states, somehow that wave took the photon in just the spots that show entanglement between photon 1 and 4.

(How the pilot wave got influenced by the future event of photon 2 and 3 getting entangled? )

And so on with all the interpretations...

Thanks all! =)
