ENTERTAINMENT WEEKLY: Lena has come dangerously close to learning the truth about Supergirls identity.

Will that come to fruition during the finale?KATIE MCGRATH:I kind of hope you dont.

With Lena, Kara can just be Kara; she can be Kara Danvers, not the superhero.

She doesnt have this weight and this responsibility on her.

All she has to do when shes with Lena is be a good friend.

The longer that you dont ever see that, to me, the better.

On the one hand, you could look at this season as the Lena Luthor origin story.

But wouldnt it be great to know that you are constantly surprised that shes not?

Youve got this thing of who she is versus what she is versus who you think she is.

We havent seen a Lena before; weve really only seen very much a Lex and a Lionel.

You know what they are.

The writers and the execs and the fans, to a certain extent, everybody is part of that.

You realize that, at some point, shes going to have to know.

[Laughs]

Had to try!I know you did, and bless your heart for trying.

The hurt from Rhea was so unexpected and so raw.

With Lillian, shes almost used to it.

She isnt surprised when Lillian betrays her or turns her back on her.

Its an old wound.

But with Rhea, its so new and so fresh, in a way, it hurts more.

Shes hurting so much from Rhea, I think shes more trusting of Lillian because of that.

Are Mon-El and Lena technically married?

So Im going to go with: I have no idea.

Wouldnt it be fun, though?

Rhea basically said all she needed was DNA to make a Mon-El/Lena child.

As a result, all of us in it, we question everything.

Were like, Is this important?!

Is this going to become a person in the next season?!

Im thinking, Are we going to see this, ultimately amazing, child?

We dont know, but wouldnt it be interesting?

But I dont know.

Just wait and see, I guess is what my point is.

Jesus, have you seen all the stuff she has to do?

She has to save National City, she has to find her boyfriend.

Where does a girl find the time?

Supergirls season finale airs Mondays at 8 p.m.

ET on The CW.
