Not a bad hypothesis Robotron. The "save April" issue is one of the main issues I've been grappling with. I agree that Kian would have done a much better job killing her if he hadn't had that rediculously abrupt change of heart (he must be the most impressionable person ever), but I think it's more than that. I'll get to my theory in a second.
Someone pointed out on a message board that all the arcadia stuff could be basically taken out of the game and the whole story in stark would stay in tact. So that being said, why was it important for Zoe to go to Arcadia? The only one that seems to know the answer to that is the white dragon.
She was the one that felt april needed saving, and she was the one that managed to find a person (faith) who could recruit Zoe to come to Arcadia. What angle is she playing? Any speculation on her ultimate goal?
Now my theory on how Zoe saved April: Zoe sent april on a journey where she refound Crow and found out she could still shift. I think she opened a shift to safety (back to Stark? I can imagine a scene where Emma finds April in a hospital) which she couldn't do if Zoe hadn't sent her to meet the white dragon.
