Hey everyone! It has been awhile. I've thought about the Marle Paradox recently, so here is my latest effort to tackle it (after failing to do so with my Dreamline and Time X ideas.) It isn't fully fleshed out - just something that hit me earlier today. I'd like to submit it now for review, even though it is in its infancy and I haven't fully checked it for conflicts that arise later in the game if it is applied. Basically, I took the Dreamline viewpoint that values perspective, removed the Entity from it and focused on the characters that we play as in-game. The only issue I know of is that this idea (which hopefully isn't similar to other ideas presented recently, I haven't read up on everything - sorry if it is) is pretty much created with the sole intention of resolving the Marle Paradox, without influencing other events in the game - making it feel kind of forced. Any feedback is appreciated - thanks!
Time Traveler Synchronization
For all time travelers passing through a gate, the receiving era is synced to their experience, creating a tangent worldline that only grants them Time Traveler Immunity and discards Time Traveler Immunity previously granted to all time travelers on the parent worldline. If another time traveler enters the same era AFTER the arrival of the time traveler who created the tangent worldline, TTI is granted to them as well, from the perspective of the tangent catalyst.
In the game, we play from the perspective of Crono being the tangent catalyst because we first view 600AD (the receiving era) from his perspective and there are no breaks during his stay there.
First Time Travel Event: Marle Perspective 1000AD – 600AD:
Marle takes the gate in Leene Square from 1000AD to 600AD. There, she is mistaken for her kidnapped ancestor, Queen Leene, and is taken by the guards to the castle. Soon after, Crono shows up and Marle reveals her true identity to him. (Reasonable speculation follows.) Lucca arrives in 600AD, runs up to the Queen's quarters, discovers that Crono is there with Marle, and confirms her suspicion, as stated in the game, that Marle is really Princess Nadia. Lucca notes that someone was supposed to have saved the real Queen, but that may no longer happen because everyone assumes that Marle is the Queen. Lucca suggests that she and Crono go and search for the real Queen, knowing that Marle would not be able to leave the castle. The two discover the hairpin with Guardia’s royal crest in the cathedral, are ambushed by Mystics, meet with Frog, kill Yakra and save the real Queen and the Chancellor. After being thanked back at the castle, Crono, Lucca and Marle say their goodbyes and return to 1000AD.
Second Time Travel Event: Crono Perspective 1000AD – 600AD:
Crono follows Marle through the gate in Leene Square from 1000AD to 600AD. When he arrives at the castle, Marle reveals that she is truly Princess Nadia. After a brief discussion, she vanishes from existence due to a variant of the Grandfather Paradox that is satisfied by circumstances not made expressly clear in the game. Unsure of what to do, he descends to the hallway adjacent to the throne room and runs into Lucca, who explains that Princess Nadia vanished because her ancestor, Queen Leene, was supposed to have been rescued but never was. She suggests searching for the real Queen and the two head to the cathedral, where they find a hairpin with Guardia’s royal crest. They are ambushed by Mystics and meet Frog, who aids them in killing Yakra and saving the real Queen and the Chancellor. After arriving back at the castle, they discover that Marle has reappeared in the Queen's quarters due to the variant Grandfather Paradox's issues being resolved. After being thanked for their daring rescue, Crono, Lucca and Marle say their goodbyes and return to 1000AD.
Third Time Travel Event: Lucca Perspective 1000AD – 600AD:
Note: Unless one of Crono’s ancestors (perhaps a guard taken prisoner in the cathedral) is threatened, there is no reason to believe that Lucca’s account would differ significantly from Crono’s account above.
Process:
Marle Perspective:
Marle travels 600AD --> new worldline created/Marle granted TTI --> Crono travels 600AD (Marle worldline)/Crono granted TTI --> Lucca travels 600AD (Marle worldline)/Lucca granted TTI
Crono Perspective:
Crono travels 600AD --> new worldline created/Crono granted TTI --> Lucca travels 600AD (Crono worldline)/Lucca granted TTI
Lucca Perspective:
Lucca travels 600AD --> new worldline created/Lucca granted TTI
In-game Experience:
In the game, we view the event dubbed the “Marle Paradox" from Crono’s perspective. If Time Traveler Synchronization (TTS) is observed, Crono, by default, is granted TTI and Lucca is granted TTI upon arrival. Marle is unfortunately part of Crono’s synchronized arrival and her TTI granted by her travel event is discarded. In other words, Marle is subject to causality from Crono’s perspective because she isn't granted immunity from her prior time travel event – she is both a part of 600AD and dependent upon events that occur there. Though there is more than one way this story could have gone, all perspectives can be reasonably seen to lead to the same conclusion: the real Queen is saved and our three heroes from 1000AD return home.
Additional Note:
This is meant to explain why Marle is able to disappear at all - not necessarily what made her disappear and why it happened when it did. Hopefully, with more discussion, we can work that part out and get this game that much closer to having a completely consistent approach to time travel. Thanks for reading!
