but if have a photon having high uncertainity in position then there might be the probability that localising the particle at say 2nd stage would produce an interference pattern at atleast 3rd stage regardless of the fact of being showing it's particle nature
the "collapse of the wave function" is instantaneous, the moment you detect it, say at the 2nd stage, it "becomes" a particle...

however if it goes through slits on the 3rd stage and we don't find will get an interference pattern...

so now you have which-way in 2nd slit and interference pattern in screen at 3rd stage......

you now have which-way and interference to speak/in a sense.....however these are separate events...:)
