What happens if the slit screen is removed between the slits and detector?

What is detected on the second screen if after a photon went through the slits but before it hits the second screen, the screen with slits is removed (or both slits are closed)?

The photon is not otherwise affected if it has already passed the first screen.

What happens if the slit screen is removed between the slits and detector?
