Weve never really seen the big bad become the big bad, executive producer Andrew Kreisberg says.
The journey that Reign takes this season is watching her realize her heritage and see how it manifests.
Considering shes a Worldkiller, she probably wont take it well!

So the one thing that shes great at is being Supergirl.
What can you tease of the Mon-El story line?
Can you say anything about his particular mindset when we see him again?I really cant.
Lets move on to Reign.
When we meet Reign, shes just a woman.
Im sure a lot of people are afraid of that.
What does Morgan Edge bring to the table thats different from Maxwell Lord?Adrian Pasdaris so good.
He is so good.
We loved Peter [Facinelli] and hes such a good guy.
Morgan Edge is just bad, and Adrian is crushing it.
Theres a lot of Lena-Kara adventures early on in this season.
Anything you’re able to tease on the four-way crossover?
You mentioned each of the characters dealing with their humanity this season.
Can you expand on that for Jonn?Carl Lumblywill be joining as Jonns father.
First of all, hes so amazing.
Jonn has always felt like an alien.
The four people really dealing with that theme are Kara, Alex, Jonn, and Sam.
