[WARNING: The following contains spoilers from Supergirl's latest episode. Read at your own risk!]

Supergirl really can't trust anybody these days.

On Monday night's episode of Supergirl, viewers saw a glimpse of something rather strange at the Department of Extranormal Operations (DEO), and we don't mean an alien or artifact from Fort Rozz. Although Kara (Melissa Benoist) missed seeing the moment, head honcho Hank Henshaw (David Harewood) revealed a very surprising trait: glowing red eyes.

Do vampires or robots exist in National City? Or maybe he just needs a few jugs of Visine (it gets the red out). We turned to executive producer Ali Adlerfor answers.

How CBS' new Supergirl is a hero for our time

What is going on with Henshaw's eyes?

Ali Adler: With all of the characters, there's much to learn. Hank Henshaw — I don't know how much I can say about his character, but there is a very deep, rich backstory that we'll be exploring throughout the season.

Will part of that backstory explore the family that he had said he lost?

Adler: We'll definitely explore that.

Do the red eyes indicate he's evil?

Adler: Don't judge a book by its cover, and sometimes the cover is right. I'm being purposely mysterious, I think.

Switching to Kara's Aunt Astra (Laura Benanti), will we learn more about her mysterious goal that got her sent to jail?

Adler: Any good villain doesn't think they're a villain. I think Astra is here to do what she could not do on Krypton. She's here to try to help us.

Everything you need to know about Supergirl

Now that Astra survived getting stabbed by a Kryptonite dagger, she has a sample of the substance. Couldn't she figure out how to nullify the effects or use it against Kara?

Adler: I think you're a terrific TV watcher.

Cat Grant (Calista Flockhart) finally met Supergirl. What sort of dynamic will they have for the interview?

Adler: The next episode will set up their dynamic for the series. Cat, who is used to being the most powerful woman in National City, can't help but be blown away by the power of this girl.

Does Kara know what she's getting into with this interview? Cat Grant is the most aggressive reporter out there.

Adler: There's a reason that Cat Grant is the queen of all media. That's actually the story for the [upcoming] episode: "What have I done?" Superman famously does not talk to the press, and Cat's superpower is being a tremendous interviewer. We'll see what comes of that.

Does Winn (Jeremy Jordan) have a real shot with Kara? He's in the friend zone already.

Adler: Definitely. We explore all of these emotional triangles and quadrangles throughout the season. He's awesome, and Jeremy Jordan is awesome for the role. You really root for him, and we'll definitely explore that.

17 times Melissa Benoist was Supergirl for real

What parent-child themes will we explore? We know Kara lost her parents, but she has adoptive ones as well.

Adler: That theme is constantly explored. Who we think our parents are and who they actually are is something that challenges every single one of these characters. Kara has many mothers and fathers. We saw Robert Gant and Laura Benanti on Krypton. Kara is raised by Dean Cain and Helen Slater [on Earth]. She also has Cat Grant in the form of a mother as well.

Will we see Helen Slater and Dean Cain again?

Adler: Yes, we absolutely will, and it's very exciting. We'll see them in flashback and in modern life.

Supergirl airs on Mondays at 8/7c on CBS.
