Penrose (2004: 606, 607):
What is the quanglement perspective on these matters? On this picture, it is not correct to think of either measurement (mine or my colleague’s) as effecting the reduction and the other (my colleague’s or mine) as measuring the reduced state. The two measurement events are on an equal footing with one another, and we think of the quanglement as providing a connection between these events which correlates the two. It makes no difference which event is viewed as being to the past of the other, for quanglement can equally be thought of as propagating into the past as propagating into the future. Not being capable directly of carrying information, quanglement does not respect the normal restrictions of relativistic causality. It merely effects constraints on the joint probabilities of the results of different measurements.

From the perspective of Systemic Functional Linguistic Theory, entanglement refers to the interdependency of instantiation probabilities in the system of quantum potential. This means that the instantiation of one state, through observation, affects the instantiation probabilities of other potential states, but importantly, the instantiation of the affected state only occurs when an observation is made. In the thought experiment, this occurs only at B on Titan and at A on Earth.
Accordingly, B' is the time on Earth at which the first state is observed on Titan (B), and A' is the time on Titan at which the second state is observed on Earth (A).
B" and A" are a different matter, since they are concerned with information flow between Titan and Earth. B" is earliest time on Earth that news of B on Titan can arrive. A" is the latest time on Titan that information can arrive on Earth at the time of A.
Because entanglement is a feature of quantum potential, there is no actual propagation of entanglement, since it is instances that propagate, not potential.
