And who is the man in the iron mask?
What can you tease of what were learning in Tuesdays episode?
One man went one way and one man went the other.
The template was set at a very early age for both characters.
Will this actually make the audience feel any sympathy toward him?
In the promo, it doesnt seem like he has any regret over what he did.
It almost seems like hes sociopathic.
Oh, youre absolutely right.
Honestly, just as an actor, that began to happen in the shooting of this scene.
I think theres this whole other thing here.
Im personally hopeful that that happens.
My hope is that its there.
What can you say of why Hunter really became Barrys mentor?
Were going to flesh that out.
Were shooting the finale right now.
Between whats about to air and what were shooting now, a lot of that will be fleshed out.
The seeds are planted for that when he gets there.
Did Hunter ever really care for Caitlin at all?
Thats something that Andrew Kreisberg, from the beginning, wanted to hammer into me.
While there were games being played on all the other members of S.T.A.R.
Labs, what he felt for Caitlin was the real deal.
That adds a really interesting dynamic to this moving forward.
He essentially is one gigantic liar who has played them all, but he never played her.
There are real feelings there.
Did you always know that Jay was ultimately the bad guy?
I remember saying to you, No, as far as I know, Jay is on the level.
That was not entirely true.
I couldnt obviously say what was coming.
I was hoping against hope because I was really enjoying being Jay Garrick.
I had grown quite attached to him.
So, I knew.
I hoped it wasnt going to happen, but here we are.
I didnt know who the guy was.
I didnt even have a clue.
All has been revealed to me.
I can promise that it will be revealed and it will be quite satisfying.
The Flashairs Tuesdays at 8 p.m.
ET on The CW.
