So, I watched The Flash season 5 episode 8 (What's Past Is Prologue), and one thing got me confused:
When Barry went back to the time where his speed had been taken by Hunter Zolomon (a.k.a Zoom) and after successfully finding the device, while he was returning from that time with his daughter, Zoom followed them and a Time-Wraith caught Zoom inside 'The Speedforce' (@16:45 min).
Shouldn't that change course of history where his dad (Henry Allen) is never killed by Zoom and is alive in the future? (Yeah, time-travelling is tricky 😅).
