When there are two polarizers A and C, which are rotated by 90 degrees to each other

Now let's say we have two entangled photons travelling away from each other. If we send
photon #1 through polarizer A right before photon #2 goes through polarizer B,
How about a clarifying diagram. In the first para B was between A and C, now it seems
it's in the opposite direction of A relative to the source. And you're talking about
"right before" referring to events which are space-like separated, which is ill-defined
per relativity.
I think the answer though lies in the fact that a polarizer will cause both photons to be
absorbed or to assume that polarization.

right before photon #1 goes through polarizer C, then if I understand entanglement
correctly that implies some of the time photon #1 will make it through polarizer C. Is
that correct?
To me it seems that must be incorrect, because it would enable super luminal
communication. By sending a continuous stream of entangled photons in opposite
directions and changing the orientation of B between 0 and 45 degrees, you could cause
photons at C to stop with 100% or 75% probability. This cannot be so then what is wrong
with the above assumptions of how the three polarizer experiment works with entangled
photons?
Thanks,
Jason
