User blog comment:TheDoctor230/Savitar Plot Twist/@comment-27700324-20170308025850

Well i think the reason why Wally isn't in the future is because the timeline is in constant flux. Jay and Rip have said this many times. Jay also told Barry that he doesn't know if Savitar will kill Iris cause that future is only a possible one. My point is that a timeline where Wally comes in the picture might happen, but it isn't the one Barry found. The problem is that they will never find the current version cause they keep on vibing to the future Barry saw.
