We know that Eobard Thawne killed Barry Allen's mom and that caused Barry Allen becomes CSI. So that when he was working late he got an accident ect. and becomes Flash.

My question is how Barry Allen becomes Flash if Eobard doesn't exist yet?

Or, how Eobard Thawne has speed force in the first place so that he travels past to kill Barry Allen's mom and caused him to be Flash?

@galeme:

Sorry, couldnt resist

So if this meme is right, that would mean that:

• In the original timeline , barry had a normal life with his parents before becoming the flash
• in the future thawne gains his powers and develops his hate for Barry, then goes back and kills Barry's mom
• since he's protected from any changes to the timeline, this doesn't effect him at all

@galeme:

The Flash (2014) s02e11 Episode The Reverse-Flash Returns :

@webinyoureye11:

• in the future thawne gains his powers and develops his hate for Barry, then goes back and kills Barry's mom

But how is that possible? For thawne gaining his powers, there must be Flash before him right?

@galeme: well Barry would still have been the flash. He just wouldn't have lost his mom in the original timeline, not until thawne changed it at least

No because they don't get their power from the same source.

@webinyoureye11:So there could be a universe Barry Allen is Flash and his mother still lives.

Well, i think that might be.

But i still didn't understand how Barry becomes Flash if his mother isn't murdered?

Anyway, thanks for answering.
