It took CBN's own Chris "DOC" Bushley to explain Flashpoint #5 to me - cuz I really had no freakin' idea what happened!
What were the three universes? Old DCU, Flashpoint, Wildstorm. Wait was there Vertigo? Is that four? Or is Vertigo apart of Old DCU? Or something else?
Which U. was The Flash and Batman in at the end? Oh, it's all about the costumes!
So The Flash's mom is still alive? No, she's dead?
Which Flash was time travelling and where? Both? Who and What again about Thawne?
Okay, I think I got it.
My last question to the DOC was: Who was that chick? (Yes, actual question)
No idea, and it turns out, I guess, no one knows.
But hey, I missed this: She appears in BOTH Flashpoint #5 AND Justice League #1!
And here I thought DC was trying to clear there U. up with the Relaunch/Reboot. What's that you say? Earth 2...too!?
Here is the Mystery Girl from FP#5 and JL #1 (bottom right corner). Credit Bleeding Cool for this one:
