Much like "Gotham" viewers, Jessica Lucas has questions about her character's past, present and future. But there's no question that as Tabitha Galavan, the actor has cemented her place among Gotham City's most dangerous and intriguing residents. Which is no small feat considering her character is one created specifically for the television series, with no comic book counterpart to draw from for inspiration.

Along with her brother Theo (James Frain), Tabitha has been instigating chaos and causing bloodshed across Gotham City's pre-Batman-protected skyline. Ahead of tonight's episode, "The Son of Gotham," Lucas spoke with CBR about what happens as Tabitha continues to strike out on her own, getting physical with Alfred (Sean Pertwee) and the twisted sibling rivalry she and Theo have developed over Barbara Kean (Erin Richards).

CBR News: Tabitha Galavan doesn't exist in the comic books, so there was no source material for you to look to in preparing for the role. How did you go about finding her voice?

Jessica Lucas: I had an official conversation with Danny Cannon when I booked the role about what their plan for her was. Really, all I had to go on were the scripts in creating her. I had to slowly build her as information was given to me [in the scripts] because I didn't have a lot to go on.

Right away, Tabitha demonstrated a knack for guns, whips and sharp objects. How proficient were you with those various weapons beforehand?

Not at all. I've done a lot of genre projects, but I've never even shot a gun on set before. It was a very steep learning curve for me. I was thrown on set with a whip on the very first day. The stunt team on our show is tremendous and has been very patient with me. It's been great and a lot of fun.

For a while, there was a creepy love triangle developing between Tabitha, her brother Theo and Barbara Kean. What's your take on Tabitha's relationship with the two of them?

I initially thought that was going to be more of a thing. In reading the episodes as they went on, Barbara was manipulated by Tabitha to use against her brother, to make her brother jealous and just to mess with him. They are all a little crazy. In this last episode, it seemed on the surface like she really cared for Barbara. It was more of a battle between Tabitha and Theo. Tabitha finally has an opportunity to branch out on her own, and she's reckless. He needs to be there to rein her in.

Tabitha came across as jealous at times.

Yeah, but I think that's more about Theo and Tabitha. He's in charge, so there's a power struggle over Barbara. It's not necessarily about feelings. It's more like a piece of meat has been thrown into the pen, and they are both fighting over who is going to get it.

How on board is Tabitha with Theo's grand scheme of revenge against Bruce Wayne?

That comes to light very soon. She doesn't think about the overall plan. Tabitha's there to carry out the action. She's a woman of action, and I don't think she spends a lot of time thinking about it the way that he does. I'm not even sure how she's entrenched in this whole family back story like he is.

Tabitha broke Oswald Cobblepot's control over Butch, but much like the original process that placed Butch in Oswald's control, viewers didn't see how you borke him from it. Since that happened off screen, did you and Drew discuss what exactly went down?

No, we didn't, but that storyline is something that's not fully wrapped up yet. I honestly don't know. I think it was some sort of conditioning, some sort of torture. That's the thing -- it's supposed to be left up to the imagination.

Before they broke his control over Butch, the Galavans attempted to manipulate Oswald for their own ends. In what ways did they underestimate him?

Well, they just did. I don't necessarily think there was a lot of research on who Penguin was. They just saw an opportunity to use him to assist in their plan, or Theo did, anyways. It's just been so easy for them so far. They thought if they used his weakness, which was his mother, they'd be set. They were wrong. They severely underestimated his resilience.

Since she's the one who actually killed Oswald's mother, how afraid should Tabitha be of Penguin?

I think she should be very afraid, but that's not something you are going to see play out for a while. It will be interesting to see where Tabitha goes over the next few episodes. I think people are going to be in for a bit of a surprise.

In the wake of his control over the Penguin falling apart, just as he was taking over the office of Mayor, Theo found himself arrested and thrown in jail. How does his incarceration affect their plans?

At that point, it puts a damper on things. Tabitha is on her own and has been ousted from the penthouse. She's fighting for survival. In episode 10, there's a great sequence between her and Alfred. It gets pretty physical.

There's that, and Theo is going to trial. It remains to be seen whether he gets off, and, if not, do they have another trick up their sleeves? Probably.

What pits Tabitha against Alfred in "The Son of Gotham," and how does he fare?

Up until now, Tabitha has had a lot of opponents, and they've been no contest to her. Alfred is the first person who has given her a run for her money. It makes for an interesting dynamic. It's a very exciting physical sequence. I'm really proud of it; we worked our asses off.

What else is in store for Tabitha over the next few episodes before the winter break?

Big changes are coming her way. The Order of St. Dumas is going to come to a head. That represents a lot of change for Tabitha.

How much will viewers learn about Tabitha's upbringing and what shaped her? Do you still have your own questions about her past?

Yeah, I do. I don't know. That's not really a question for me. I'm not sure what the writers' intentions are going forward. It could happen and I hope that it does because it's something I'm curious about.
