Back to Alice and Bob. Alice is trying to transmit solar flare information faster than light to Bob, say 8 minutes earlier.
Alice is sitting close to the sun, watching for solar flares.
Bob is sitting on earth.
The deal is:
Alice
if there is solar flare before noon, alice will look at the entangled photon A and collapse the wave function.
if there is no solar flare before noon, alice will not look at the entangled photon A...and let the entanglement continue...and the wavefunction would stay "intact"
Bob
Bob will look at entangled photon B at noon plus 1 millisecond.
if the photon B is already in a state that indicates the wave function has collapsed then a solar flare is on its way
if the photon B was intact but Bob collapsed it then no solar flare is coming
or in summary:
can bob (or alice) tell when looking at the photon...if the wavefunction *had* collapsed or they collapsed when they took a look?
