At the end of "Flashpoint", Season 3 Reverse Flash reappears to kill Nora Allen, while both future Reverse Flash and Season 2 Barry are erased from time. Why did this happen? Neither Season 1 or future Barry were erased from time when Barry went back in time in Season 1, nor when he went back in time in Season 2. I think they just did this as a convenience because otherwise Season 2 Barry would try to fight Reverse Flash, which would cost more money, time, and script writing to make happen, but I think this opens up a hole in their time travel logic. Any thoughts about this?
