The next morning Cat awakens alone in her bed. A note on Kara's pillow informs her that she can release the interview, although Kara may not be available for a press conference today.

Sighing, Cat rolls over and pulls Kara's pillow to her, taking a moment to savor the memory of Kara tenderly making love to her last night before curling around her and falling asleep.

Finally pulling herself out bed, Cat checks her phone for messages. Unsure of how long Kara's been gone, she then turns on the tv just to see if there's any news of Supergirl. Grimacing she watches the headlines as she clicks through the channels... Cat Grant's Super Assistant turned Super Girlfriend. Cat groans. It could be worse she realizes, at least no one's calling her a super cougar yet.

"Mom, where's Kara?" Carter asks when he sits down for breakfast.

"She left early this morning," Cat replies trying not to let him know how concerned she is. But then her phone rings and she answers it quickly.

"Cat, it's Lucy," Lucy says and isn't surprised to hear the other woman let out a breath.

"Is there any news?" Cat asks carefully.

"Not yet, Kara has joined the surveillance team against my orders, but I did have an idea. Would you consider not following your normal routine today? In fact, I'd like to send a team out to pick you both up and bring you to HQ as a precaution. My concern is that Non will use the two of you to get to Kara and it's important that he can't find you." Lucy explains rapidly.

"I appreciate your concern Director Lane, but Cat Grant does not hide," Cat replies firmly.

"I'm not asking you to hide Cat. I'm asking you to come to a secure facility for Kara's safety. She can't focus on this battle with Non if she's worrying about your safety. She needs you to do this Cat." Lucy repeats.

"Fine. When will your people be here?" Cat asks.

"They're twenty minutes out, meet them on the helipad and Cat, you have no idea how much this will mean to Kara," Lucy replies.

"Is there any news?" Cat asks as soon as she is inside the facility.

"They were waiting for you and Dr Danvers to arrive, before engaging," Lucy replies.

"Dr Danvers? Kara's mother is here?" Cat questions.

"Hello Ms Grant, Eliza Danvers," Eliza says stepping up to introduce herself.

"Hello Dr Danvers, please call me Cat and this is my son Carter," she adds nervously running her fingers through his hair.

"Hello Carter, I've heard a great deal about you," Eliza says greeting him.

"What kind of doctor are you?" he asks curiously.

"I'm a bio-engineer, I work in a research facility near Midvale," she explains.

"So are you a PHd or an MD?" Carter asks.

"Both actually," she replies. "Carter, you are quite the interviewer, are you going to be a journalist like your mother?"

"I haven't decided yet," he replies.

"Carter is twelve, so he has a bit of time to figure that out," Cat adds proudly.

"I'm sorry that we are meeting under these circumstances, but I am pleased to have an opportunity to spend time with you both," Eliza remarks.

"Hey Carter," Winn and James enter the room and Cat quickly looks over at Lucy.

"Ms Grant, we had to gather up everyone who could possibly be a target. Non is ruthless and his soldiers follow his command without question. Kara cannot be distracted on this mission," Lucy reminds them all.

"What about Alex?" Eliza asks and Lucy looks at Cat. "Is she safe?"

"Uh, Eliza step over here with me for a moment," Cat says taking the other woman's arm.

"You've spoken with Alex?" Eliza whispers.

"No, but she called Kara yesterday worried about her. She was fine and is still on her mission," Cat explains.

"I see. I know that she's a trained agent who can take care of herself, but I still worry," Eliza admits.

"Of course you do. It's impossible not to," Cat replies.

The big screen comes alive as Vasquez alerts everyone that Kara's team dropped into Non's lair. They all gather around the coms screen to watch the grainy footage of the fight.

"You stupid girl!" Non exclaims when Kara bursts in on him. "You have no idea what you're doing," he roars.

"I'm going to stop you from destroying this planet," Kara yells back.

"Your mother once thought that she could stop me but she failed," he spits out.

"I won't," Kara says rearing back and striking him, knocking him across the room. Zipping over quickly, she picks him up. "Because not only do I know pain, but I know love. And the people of Earth have taught me to protect the things that I love," she adds before smashing him again and sending him careening across the room.

The DEO task forces begins shooting at the few soldiers that have gathered to protect Non, they are carefully aiming at the Kryptonite blockers and as soon as one is destroyed then the soldier is shot with a Kryptonite bullet.

Non looks around quickly and grabs one of his soldiers and removes his blocker and wraps it around his hand to protect himself before launching himself into Kara and sending her flying backwards into his own soldiers. They attempt to hold on to her, but she's no match for them as she breaks their hold and attacks Non again. This time she wrestles him to the ground and pummels him with her fists. But he manages to break her hold and fly up and hovers above her. Suddenly a shot rings out and his blocker goes dark. He looks to where the shot came from, but before he can zap the agent, Kara intervenes. Striking him so hard that the other blocker flies out of his hand. The next shot is kryptonite and it pierces his arm. Stunned he tries to dig it out, but Kara is on him again punching and kicking him relentlessly. He manages one more burst and sends Kara flying across the room. But the kryptonite is weakening him as he staggers over to his control module and struggles to flip a switch.

Kara is on him like a flash and smashes the control console. Next she pulls out a kryptonite knife and holds it under his chin. "I can't think of one reason not to end this once and for all," she spits out at him. Her eyes on fire, her body trembling with anger.

"You have the heart of hero Kara Zor-El, you're not a warrior. Astra was the only warrior in your family," he spits out.

"You're wrong again Non," she says driving the blade into his heart and watching him fall to the ground.

Turning slowly she looks around at the remaining soldiers, "This too will be your fate if you cross me," she roars at them before taking off.

At the DEO everyone is stunned into silence. It's Lucy who finally speaks. "Vasquez get a status on Supergirl and let's round up those combatants," she orders.

"Supergirl is gone," Vasquez says after a few minutes and everyone gasps.

"What do you mean Supergirl is gone?" Lucy questions.

"She's turned off her coms and her phone. I can't track her." Vasquez replies.

Lucy looks over helplessly at James and then to Eliza.

"I'll call Kal El," Eliza says quickly.

"Mom, she did the right thing. He was a bad guy, right?" Carter asks.

"Yes, she did the right thing," Winn interjects quickly, afraid of what Cat may say.

"Carter, Kara vowed to protect all of us and she did what she had to do," Cat stammers, still trying to comprehend what just happened.

"Kara," Kal says entering the Fortress and taking her into his arms.

"K-Kal, I just k-killed Non," Kara says tearfully. "I had no choice... he wouldn't stop until he destroyed me and this planet," she adds.

"I know Kara. You did the right thing. He was ruthless. I'm just sorry that I wasn't there to help you fight him," Kal says holding her tightly.

"No, it was my fight. I just hope that I never have to do that again," she replies wiping her tears. "Kal, how did you know I was here?"

"Eliza called me, so I asked Kalex to locate you," he explains releasing her from the embrace.

"Eliza, oh my God. Cat and Eliza are at the DEO, I should probably get back," she realizes.

"Supergirl just turned her coms back on," Vasquez says softly to Director Lane.

"Get her on the line and send it to my desk," Lucy replies slipping out of the room.

"Kara are you okay?" Lucy asks.

"I am. I'm on my way back, is everyone still there?" Kara asks.

"James left but Winn is still her with Carter, your Mom and Cat," Lucy answers.

"Please tell them that I'll be there soon," Kara replies.

"Kara," Eliza says rushing to her daughter when she enters the facility and wrapping her arms around her.

"Eliza, I'm fine," Kara says reassuring her and looking over at Cat nervously. "I just needed some time to make peace with what happened," she explains, still looking at Cat.

Lucy notices the tension between Kara and Cat, so she steps in, "Supergirl, can you come with me to debrief?"

"Wait, I need a minute," she says going over to Cat. "Can we talk?" Kara asks softly.

Cat nods and follows Kara into a small room. They face each other warily. Cat unsure how Kara is after killing someone to protect her. Kara unsure of how Cat is after watching her kill someone to protect her.

"Cat, I'm sorry that you had to see that," Kara says looking down. "I've never... I hope that I never..." her voice breaks, she can't say the words.

"Kara, I understand what you did and why, I just never thought that I would see it happen," Cat replies her voice breaking as she goes to her and wraps her arms around her.

"Cat," Kara says. "If there was another way," she begins.

"Shh Kara, I've never felt so loved and protected in my life," Cat exclaims turning to kiss her.

"I was so worried that you would look at me like I am a monster," Kara replies in a soft voice.

"No my darling, you are a warrior with the gravitas of a hero," Cat replies reverently, lifting her chin and kissing her lightly.
