Its just an example of Barry being in desperation mode, Gustin tells EW.

I think anything that we can try that we havent tried, Barry is willing to try.

Were talking about the end of all of humanity as we know it.

Barrys even more apprehensive about it at first, Gustin says.

Still, Gustin notes, its a matter of opinion, not trouble in paradise for the newlyweds.

Theres not really any real Barry-Iris drama its Team Flash drama, he says.

Barry and Iris are consistently approaching things from a different angle.

But theyre still there supporting each other.

Its just that things are tense.

Its really sad in all those scenes for the whole team.

Its hard to see someone thats so brilliant kind of lose themselves.

Also, as a team member, hes irreplaceable.

When we need him most, we dont have him.

The Flashairs Tuesdays at 8 p.m.

ET on the CW.
