The next episode is about the ethics of doing that, Kreisberg says.
Are we even sure this will work?
Thats part of what the next episode is about is, Are you out of your mind?!'
This is insanity and were trusting everything on Harrys say so that its all going to be fine.
Thats part of what makes next episode so exciting.

John Wesley Shipp returns as Barrys dad in the next episode, Kreisberg says.
Why does Barrys dad come back?

Labs, it could set off another chain reaction and affect everyone in the city.
Theyre all a little bit gun-shy.
But seriously, how did Zoom get away with fooling everyone?
We think that this season happened because of last season.
They wanted to believe it.
He told them everything.
A lot of that was because they wanted to believe it.
Barry lost his mentor when Wells turned out to not be who he said he was.
He was able to do it because they let their guard down and wanted to believe it.
So then who wasJay Garrick?
The answer to that question will be answered down the line, Kreisberg says.
Its worth not talking about.

No, Kreisberg says.
The answer is going to blow your minds.
We finally got a new member of Team Flash who isnt evil probably!
Jesse is for sure now folded into the team, Helbing says.
When will Wally find out that Barry is The Flash?
There are still a few more episodes of him being how Iris was last year, Helbing says.
It takes a while before he gets fully caught up to whats going on.
Any chance Jesse and Wally will become the speedsters they are in the comics?
Right now, the show is calledThe Flash, Kreisberg says.
For the most part, Barry Allen is the only Flash.
It will never be Spider-Man and his amazing friends, itll always be The Flash.

It gave us an opportunity to deepen both characters, but ultimately she had to go.
How is Cisco handling his powers?
He feels emotionally like hes in a good place, Kreisberg says.
There are moreGreatest American Herotechnical issues, glitches coming up this season.
