What big rule do you think it is that they're going to have to break in the finale of legends ( my English is bad. So sorry)
(Your english is fine, no problem :) )
As the Legends are about to take off for their next destination, a massive timequake rocks the ship. In order to try and fix what has happened, they are forced to break the one cardinal rule of time travel. But if they are able to destroy the spear, they will face the ultimate consequence.
I’ve been thinking about this for a few days and I still don’t know. I know that @calmandcalculating has had some ideas, but I can’t think of one major rule about time travel they could need to break that they haven’t already.
For isntance, Martin’s already interfered with his own timeline and caused an aberration, even if it was an accident.
One thing they might need to do is do that deliberately? Interfere with their own timelines? I mean, Ray, Kendra, and Sara were left in the past and when they were picked up two years later, Rip said he couldn’t drop them back off and go back by two years and re-collect them before they’d had to wait so long, solely because you’re not supposed to interfere with your own timeline and they’d already been picked up.
Another would be to return to the same moment they’ve already changed, which is a big rule they’ve established. They only have a single shot to fix something in time, right? Even if they’ve returned to the old west to see Jonah Hex more than once, it hasn’t been at the same moment or for the same calamity. So maybe that’s it?
Other than that, I’m really not sure…
