What war was he talking about?
Did the war pass or is it still coming?
And how does Barry know Rip?
Time travel Barry, so very confusing. ~ Thawne
[The Future] is always turning and bending, just like there are infinite Earths in the multiverse, there are infinite possibilities to the future. ~ Jay Garrick
It was clear that if he was talking of a war to Rip, it would be about Vandal which was still inevitable.
Given the timeline has changed, I don't think Barry will say anything to Rip Hunter in the future of Earth-Prime, because he said that in the future of Earth-1.
Well Vandal Savage is core to the Legends forming so that time loop is still going on, but they'll still not address it.
What do you think?
