Another thing about ZTD that blew my mind - did you notice that the Jupiter pendant ("a mother's memento") is actually on an infinite paradox loop? Diana gets it from Phi in the incinerator, then 10 months later gives it to (baby) Phi as a memento, then gets it 'back' in the incinerator timeline - etc. Question is, where did the pendant originate in the first place? Chicken and egg anyone?:)
