Williamson gave another interview about what's ahead after Flash War. Most of the specific details are naturally about Barry, but he does talk about how Wally's story is really just starting.
Though I can't say that answer has me particularly excited since it seems to be more of the same with the potential to be worse.So much effort is put into Comics and TV and Movie superheroes trying to give them a motivation that really justifies their actions. When you show Wally his kids, forgotten and imprisoned, is it almost a free pass? That Wally can do almost anything and people won't hold it against him? Or is it a balancing act of trying to keep from being too dark since Wally is still a hero, right? But what wouldn't Wally do from here on out?
Yeah, we're trying to change the way these characters work a little bit, and put your stamp on them, add a little twist on them. I think with Wally, it's going to be a rough time. It's definitely going to be hurtful for him, and an emotional rollercoaster ride.
