No matter how many times it screws things up, Barry (Grant Gustin) just cant seem to stop himself from running back in time on “The Flash.” After all, he’s convinced it’s an easy enough way to solve problems. Take the March 29 episode — “Flash Back” — for instance.
Since he’s out of options on the best way to increase his speed and defeat Zoom (Teddy Sears), Barry decides to flash back in time to reunite with his old friend/foe Eobard Thawne (Tom Cavanagh) before the world learned he was Reverse Flash.
Of course, Harry (Also played by Cavanagh, but in the future from Earth-2) told him this was a terrible idea, but Barry convinced Team Flash that it was the only way to handle Zoom — and for bonus points, told them he could keep his time traveling secret from everyone.
Naturally, that means literally almost everyone found out. Not only did Eobard, but so did Caitlin (Danielle Panabaker), Cisco (Carlos Valdes) and past Barry. Yes, Barry met himself from the past. While you might think that could cause the timeline to sink into itself, never fear. Instead, it just led to a few jokes about time and many confused faces from everyone involved.
However, when Barry did return to his own time, he noticed a major change in the timeline. Former villain Hartley Rathaway (Andy Mientus), also lovingly known as the Pied Piper, is no longer a bad guy. Now he’s sort of a Team Flash accessory player who gets called in when needed. Who knows if that’s permanent or a one-time-only thing, but it certainly was a shock for Barry to see upon his reentry.
The bigger question left behind is how much is Barry willing to change in order to defeat Zoom — or any future enemies. We’ve all seen dozens of movies and TV shows that warn about the dangers of messing with time. In theory, Barry’s seen them too. He knows the bad he’s inviting into his life and the world. He’s so singularly focused on beating Zoom though, that he refuses to look at it through any other lens.
In the long run, that streak in him could cost many lives.
