Mafia 106. Cradle of Dragons

Once again, for the slow-witted:
Why doesn't Eon's ability affect Bjorn?

And am I correct in understanding that if, as a result of any combination of transfers, the player ends up back at their starting point, they fail?

Let's go through it step by step:

Act 1: Vasya goes to Eon, Eon sends him to Bjorn, Vasya goes to Bjorn

Act 2: Bjorn, having an action lower in the order of initiative, sends Vasya to Eon. When Vasya arrives at Eon, that action has already been completed, and he remains there. No time jumps.

An action that leads back to oneself is only successful in the case of the "Drunkenness" spell.
