CBR has posted their latest Geoff Johns Prime question and answer column. in it the Flash: Rebirth author talks about Blackest Night, Flash, Superman and a lot more.

Some Flash items that stood out:

Wally’s Costume

Back in June, Ethan Van Sciver said that Wally West’s new costume debuts in Flash: Rebirth #6, but Geoff Johns says here that it appears in #5. If that’s correct and not a typo, then I feel a lot more confident about the schedule for Blackest Night: Flash not being pushed back to avoid spoiling the costume debut.

He goes on:

And it’s very much a Flash costume. It’s tweaked, but it’s certainly not crazy. It’s not blue and white. It’s Flash. We never wanted to completely change it. We just wanted to accentuate what makes Wally’s costume, Wally’s costume. It will feel very familiar.

Hmm, hard to say, but I’m going to guess two things:

• Barry keeps the straight-across belt and Wally keeps the V-shaped belt.
• Wally loses the top of his cowl, making his hair visible.

XS

There are very big plans for XS in the future of the Flash universe. “The Flash” book and the “Kid Flash” book start next year

I think this is great. I haven’t read much of the DnA Legion of Super-Heroes, but I liked her appearances in Impulse during and around “Dead Heat.” Jenni and Bart really connected during that story, and I can see a lot of potential with two teenage speedsters who have spent significant amounts of time in the future. Plus it’s got to be a big change for Bart to go from having one blood relative around (Iris) to three (Iris, Barry and Jenni).

On the other hand, I hope XS will still be tied to the Legion of Super-Heroes, and I hope her Flash appearances are in addition to the “new” female speedster hinted at in San Diego and Long Beach.

Hey, wouldn’t it be weird if she ends up in the Justice League? (Okay, not going to happen, but she would be an “interesting” choice, wouldn’t she?)

The Speed Force

His longest Flash-related answer is to a question about why he changed the nature of the speed force in Flash: Rebirth. It’s several paragraphs long, but the part that stood out for me was this:

And literally if [Barry] builds up enough energy, just like anything else that builds up energy, boom, there’s a discharge somewhere or somewhen. A stray lightning bolt from the Speed Force that…strikes somebody that shares the same sense of justice that Barry Allen has.

This picks up from something suggested during William Messner-Loebs’ run on the book, in which he suggested that Barry Allen might somehow have subconsciously willed the accident that gave him super-speed to repeat itself with Wally. It explains the mysterious behavior of the speed force “noticing” people, though it doesn’t quite explain, for instance, Savitar — who certainly didn’t share Barry Allen’s sense of justice. Maybe he did before he gained his powers. Or maybe he gained them through a discharge from Thawne’s “negative speed force?”

(Personally, I think that these changes overcomplicate a plot device that was designed to simplify speedsters’ origins, but that’s just my opinion.)

Flash Movie

Geoff Johns says that he’s “working on The Flash” and Shazam but can’t say anything more at this time.
