According to Gustin, the duo’s first encounter may surprise viewers.

It was great having Javicia on set, great working with her.

We’ve hooked up off set.

So, it was cool to actually be on set with her.

That being said, Batwoman does have an important role in “Armageddon.”

They had to be in this story,” says Wallace.

We had to pull off a logistics nightmare, but we did it.

I just want to be in more of this.'

To which I replied, ‘You are welcome any time, ma’am.'"

Wallace is especially excited about one Batwoman moment in particular.

I can’t wait to share it with the audience.

I can’t wait!"
