A/N- Hey guys, thanks for all the reviews, I really appreciate the feedback :)

Before we get into the second chapter, I'm gonna answer a few questions that leapyearbaby29 had and you had quite a few!

So here we go;

So firstly, you'll have to read on to find out what the demon thing is, secondly, Lena not telling Kara she had a son and why will be revealed, I can't give it away right now. Also Lena didn't have a choice about having Max stay with her because she wanted to look after her son but also she wanted to see Kara at the same time, hoping that Kara wouldn't suspect anything and lastly, the demon thing said 'damn' because his aim to was kill Max, who as you know is Lena's son, and because he's alive, it meant that he failed.

Hope that cleared everything up.

Enjoy chapter 2!

Kara stared at Lena as she stood by Max's side, the protectiveness of a mother shining through.

"Why...why didn't you tell me you had a son?" Kara asked, looking at Max.

Max looked up at Kara and gave her a small smile. Of course he didn't know who she was, Kara had perfected the art of hiding who she was over the years.

None one in their right mind would think that meek and mild Kara could actually be Supergirl.

Supergirl was confident, strong and had powers! Kara...well she just worked at Catco.

Lena looked straight into Kara's eyes and the blonde knew that she was going to get the honest truth.

"Everyone hates me Kara. If they knew that Max was my son, they would have gone for him, made him a target and used him against me."

"But he's in school, how have you covered parent's evenings, school plays, bringing him home every night?"

Lena stepped away from Max and went over to Kara, lowering her voice she said;

"He's still a little shaken. Perhaps we could talk downstairs?"

Kara nodded and Lena followed her out of the room, shooting back a little assuring smile at her son.

Back downstairs, Kara turned to face Lena, her arms folded and a serious look on her face.

Lena gave her a silent nod, confirming that she would now answer all of Kara's questions.

"Parent's evenings and school plays were covered by an actress. She would go into the school, pretend to be his mother and attend and film everything Max was in, then she would bring the tapes to me. Only a select trustworthy few at the school know that I am his real mother. Max doesn't come home because not only is the school private but it's also a boarding school for the rich who are willing to pay for them to house their children. I want him home with me but as I said, I'm a Luthor and my world is not safe for him."

Kara frowned slightly.

"But he's here with you now."

Lena nodded.

"He's here because there was an attack made on him which means that someone knows who he is. I can't afford to have him out of my sight now that someone knows he's my son."

Kara nodded.

"Final question; why didn't you tell me?"

Lena lowered her head, not being able to look Kara in the eye. She could hear the hurt in her friend's voice and she knew that it was down to the fact that Kara thought Lena couldn't trust her with this kind of information but then she also knew that the Luthor woman was very secretive. It was just a part of her that Kara had come to accept but this...this was something else.

"I can't get into that right now." Lena said softly.

"Don't you trust me?"

"Of course I trust you!" Lena said, her eyes meeting Kara's as she moved forward and took Kara's hands in her own.

"It's just...it's difficult to explain."

"Well try." Kara said, pulling out of Lena's grip.

"I can't..."

Kara sighed as though she was disappointed.

"I wanted to tell you! I really did but I just didn't think that you would-"

"That I would understand?" Kara snapped.

"No, not that but...it's complicated."

"It's always complicated with you Lena! Why couldn't you just tell me! I could've helped you!"

"Helped me how?!"

"I-I know Supergirl. She could protect him!"

"Yes but she can't watch him 24/7 while I'm at work."

"So what are you going to do? Take him to work with you?!"

Lena stared straight at her, daring her to argue.

"Yes. That is exactly what I am going to do. Now if you have a problem with that, you can leave."

"I don't have a problem with that. I just wanna know why you didn't tell me."

"And I told you I can't."

"Will you ever?!" Kara shouted, unable to help how she felt.

Lena let out a breath and her eyes looked sad.

"I don't know...I would like to think that maybe one day...but now? I don't know."

The two women stood there in uncomfortable silence until Kara turned and headed for the door.

"I should go."

Lena didn't stop her this time.

"Yeah, maybe you should."

Lena watched as Kara opened the door and slipped outside, quietly shutting it behind her.

Lena was so used to people slamming the door on her when they got mad that she didn't know what hurt most.

Letting out a breath, Lena went over to the table and started clearing the pizzas and ice cream away.

"Mom?" She heard Max call from upstairs.

"I'm coming sweetie." Lena replied and slowly made her way back upstairs, all the while thinking of how to explain things to Kara or even if she could.

"So what have we got?" Kara asked as she stood in front of Alex and J'onn.

"Not much. We've looked it up based on what you've said but we can't find an alien that can transform into a demon at will, at least not one that looks like what you described." Alex told her.

Kara stood with her hands on her hips, her Supergirl costume on as she knew she needed to be ready at a moment's notice.

"Is there anything unusual that has gone on? Has anyone else seen this thing?"

Again. Alex shook her head.

Kara clenched her teeth and her fists tightened as she brought them down on the table, doing her best not to break it.

"There must be something." She growled.

Alex looked at her sister and knew something was wrong.

"Kara? Can I have a word?"

The blonde frowned but nodded her head anyway as she allowed herself to be pulled to the side, out of ear shot of everyone else.

"What's going on with you?" Alex asked gently.

"Oh it...it's nothing."

"Come on. I know when something's wrong with you. Just tell me."

Kara sighed and bit her lip.

"It's Lena."

Alex frowned slightly.

"What about her?"

"She was at the children's hospital yesterday. I thought she was there to check up on how things were going but it turns out...she was there to see the kids-one kid in particular."

Alex's frown deepend.

"I don't get it."

Kara looked around before she lowered her voice a little more.

"That boy I saved, you know, Max?"

Alex remembered Kara telling her about him and how the demon thing seemed more concerned with him and why if he'd survived the fire.

"Yeah."

Kara let out a breath.

"Max is Lena's son."

Alex's brown eyes went wide.

"What?"

"I know..."

"Why didn't she tell you?"

Kara shrugged.

"She said it's complicated."

Alex nodded as she listened to her sister.

"Do you uh, maybe want me to have a word with her?"

Kara frowned slightly.

"No offence but what would that do?"

Alex folded her arms and shrugged.

"I dunno but maybe I can talk to Lena, make her understand where you're coming from and get her side of the story. Maybe she'd feel more comfortable talking to me, it's just a suggestion."

Kara nodded.

"OK...if you think it'll help."

Alex nodded.

"Where is she now?"

"I don't know. She might be at work, she might at home but she said she would be bringing Max to work with her so that's where I would try first."

Alex nodded.

"OK. I'll be back soon." She told her sister, silently promising that she wouldn't come back without a reasonable explanation, even though she thought she knew what that could be, she couldn't tell Kara. Not yet.

When Alex arrived, Lena was at her desk.

Max was nowhere in sight but then Alex expected that. There would be too many questions if anyone saw him.

"Alex! It's so good to see you!" Lena said as she stood.

Alex smiled and they hugged a little awkwardly.

"Please, sit. How have you been?" Lena said cheerily.

"Good thanks. You?"

Lena shrugged.

"Can't complain."

Alex knew she had to say something otherwise they would be exchanging plesantries all day.

"Lena, I have to talk to you about something."

Lena looked up and the smile instantly disappeared from her face.

"Kara." She said knowingly.

Alex nodded.

"She told me that you were keeping something from her. I won't say anything, I swear. I know how important it is to keep secrets to protect the people you care about."

Lena nodded along to what she was saying but Alex could tell by the tightening of Lena's jaw that she wasn't happy that Kara had told Alex about Max.

"She just wants to know why you didn't tell her?"

"Do you think she had a right to know?" Lena snapped.

"Well, she is your friend and I guess to Kara it looks like you don't trust her."

"Don't trust her? Alex, I'd trust Kara with me life! How could she think that?!"

"I came here to tell you my theory, if you want to hear it."

Lena rolled her eyes and sighed.

"Go on then." She drawled.

Alex looked straight at her.

"You were scared that Kara wouldn't like the idea of you having a child, because to you, you'd think she'd look at Max as baggage from a past relationship."

Lena's grip on her pen had tightened, Alex could see her knuckles turning white.

So she was getting somewhere.

"Tell me if I'm out of line here Lena."

"Don't worry, I will." Lena assured her but her voice shook a little, betraying her own confidence.

"Kara isn't just a friend to you...is she?"

Lena blinked quickly and her whole posture stiffened.

Alex pushed on, despite seeing how uneasy the Luthor woman looked.

"That's why you couldn't tell her. Because as Lena, you're free to do what you want. Anytime Kara wants you, you're there without question but as Lena the mom, you think that she's gonna think you wouldn't have time for her and gradually, you'll grow apart. Is that right?" Alex asked, her voice soft.

Tears came to Lena's eyes and she closed them as they fell down her face. She bit her lip and nodded.

Alex reached for a tissue and handed it to her.

"You love her, don't you Lena?"

Lena nodded without saying a word.

"And you think Kara wouldn't want to take a chance on you if you had a child."

Again, Lena nodded.

Alex really felt for her. She'd had to bury her own feelings once upon a time before she met Maggie and Maggie had made her brave enough to confront and deal with who she really was. Lena hadn't had that but she was hoping that Kara could do it, Alex could see it in her eyes whenever they talked about her or when Lena was in the same space as Kara, pure adoration was written all over her face and Alex felt for her, truly she did.

"Do you want my advice Lena?"

The Luthor nodded as she dabbed at her eyes with the tissue.

"Tell Kara. At least you'll know either way."

Lena shook her head.

"I can't. She loved Mon-El. I'm not someone she could ever feel that way with. I'm not an idiot Alex. I know when to pursue something and when to just admire from a safe distance. Why do you think I make a good business woman?" She added with a humorless chuckle.

Alex gave her a small smile and got to her feet.

"The choice is your's but if you need to talk, I'm here, OK?"

Lena nodded.

"Thanks Alex." She said with a little sniffle.

"You're welcome."

As Alex turned away, Lena stood up quickly.

"Alex, you won't tell Kara about any of this, will you?"

Alex shook her head and smiled.

"No. Your secret's safe with me."
