A game changer ( I thought that Wally was talking about the Time Bureau but in fact it was the Legends that he was talking about) that there are events in history that are fixed while there are other events in history that are soft/changeable. Go to 42 minutes and about 20 seconds or so. This game changer was possible in the DC comics because of the storyline ideas of Multiversity, Hypertime, and actual historian theories of what ifs.
