Supergirl stood about 10 feet away from the burning apartment and studied the scene. The firefighters were struggling to control the fire, and she overheard them say that people still inside. She could hear screams of a family trapped inside the building, and flew towards the window. The heat was intense, even for her. Taking a step back, she began blowing her cold air at the flames. When they died down, she flew into the room and searched for the family. It was difficult to see due to the smoke and flames, so she used her super hearing and heard the cries of a child coming from a room in the back. Within seconds, she flew towards the sounds and found them. A man and woman huddled together, shielding two small children from the flames. Kara walked over and attempted to pick up the four of them at once, but the man shook his head.

"Take them!" He yelled, pushing his family towards her. He noticed the hesitation on the hero's face and nodded his head at her. Kara picked up the woman and children, held them tightly, and flew back outside. Once they were a safe distance away from the danger, she placed them gently on the ground.

"My husband!" The lady exclaimed, hugging her two girls. The youngest one, three or four looked up at Kara, fear and confusion on her little face. At that moment, there was a crash from the building. The toddler began crying, which made Kara's chest tighten. She told the family to stay where they were and took off back to the apartment .

Once inside, she went back to the place she left the man, but couldn't see him. She began to panic, looking around what was left of the home, calling for him. An image of the rest of the family flashed through her mind. The thought of this man's wife and kids living without him, knowing he wasn't saved killed Kara. It reminded her of her own sister, Alex, and how her father is no longer around either. She shook the thoughts away and looked for him again, flying through flames and broken down walls. Suddenly, she heard coughing coming from the front of the house. She flew towards it, and found the man struggling to get out the door. Without warning, she swooped in, grabbed him, and made it out safely before the roof above the space they were just in collapsed.

"Thank you so much!" The mother exclaimed as she hugged her husband and young daughters. She looked up at Kara.

She smiled and placed her hand on her arm. "Just doing my job," she replied sweetly. And with that, she took off and flew back to see if she could do anything else to help.

When she returned, the firefighters had managed to put out the remaining fire. A few came over to her and exchanged their thank yous, and Kara knew it was alright to leave. Before taking off, she spotted a girl standing in the alley next to the apartment. She was about seventeen or eighteen years old, her long, wavy blonde hair glowing from the light coming from her hands. Kara looked at them and saw flames coming from them. But the girl didn't seem to be in distress. She looked pleased with the situation as she studied the scene. Kara took a few steps in her direction, and called out to teen's head shot up, her facial expression turning into anger. She threw her hand out, flames suddenly appearing in a circle around Kara and preventing her from coming any closer. Kara quickly put them out as she had just done before, but it was too late. The girl had already disappeared.

"Supergirl. Supergirl, are you there?" A familiar voice spoke in Kara's ear. It was Alex, a hint of concern in her voice.

"Yeah, I'm here. On my way back," Kara replied. She took one more look around, hoping to see the mysterious girl before heading back to the DEO.

…..

"What happened out there?" Alex asked her sister when she returned to the DEO. The two walked back to the main room, Hank following close behind.

"There was a girl. Seventeen, eighteen, near the house," Kara told them once they were standing next to Winn.

"So what?" He asked, stuffing his face with red vines.

Kara looked at him, then at Hank, then at Alex before saying, "Her hands were on fire. But she wasn't in any pain."

Alex exchanged her a concerned and interested look. "Alien?"

"Must be," Kara replied. "And not exactly looking to be the next Supergirl. That fire was definitely intentional."

"You sure?" Hank asked, crossing his arms.

Kara leaned her hands on the table and paused before responding, "The look on her face makes me think so. She looked, satisfied. Like she was proud of herself."

"If that's the case, we need to find her," Hank said. "The last thing we need right now is a young, dangerous, careless kid with powers out there."

"We'll get on that as soon as possible." Alex assured her boss.

Kara stood up straight and turned to them.
"But, not right now. I have to do some stuff for work and if I don't go in tomorrow with it done, Cat will kill me."

Hank nodded. "Tomorrow. This girl is now our top priority."

…..

"How do you now she'll be here?" Alex asked her sister as the two of them rummaged through the rubble of the burned down apartment. Kara knelt down and moved some pieces of metal out of the way, seeing if there was anything there to lead them to the girl.

"I don't," she replied. "But I'm hoping there's something here that can help, or maybe she'll show up again."

The two women made their way to the spot where Kara had found her the previous day.

"This is where I saw her," Kara said. "When I called to her, she was not happy."

"That's because you, like every other good person on this planet, thinks they can just come on in and ruin everything."

Kara and Alex spun around to see their target standing directly behind Alex. The girl grabbed Alex and threw her into the wall next to them.

"Alex!" Kara cried, flying at full speed towards the teen. She crashed into her and they both went tumbling on the opposite side of the alley. Kara held her down, but the girl lit up her hands and arms with fire until the pressure was too much for her opponent. Kara let go, giving the girl enough time to stand up. It was then that she realized her shoulder was popped out of it's socket. Without hesitation, she put it back in, barely reacting at all. Kara gave a small laugh.

"No pain, eh?" She said.

"Not really," the younger one replied with a smug expression. "But it looks like she feels some." She said, nodding towards Alex. Kara turned around with wide eyes, seeing Alex wincing in pain but trying her best to stand. She flew towards her, helping her up.

"You okay?" She asked.

"Yeah- Kara watch out!" Alex warned.

Kara turned and saw that the other girl was simply not giving up. She lit her hands on fire again and put another flame circle around her. Kara managed to push Alex out of the way before she was also surrounded. While she proceeded to put the fire out again, the teen was distracted, not noticing Alex come up behind her and knock her down. They struggled for a bit, but Alex took advantage of the surprise and was able to put a metal-bracelet type object around her wrist. As the girl was pinned down, she attempted to push Alex off but noticed her strength was no longer there. Neither was her fire.

"Don't bother." Alex told her. "This," she said grabbing a hold of the bracelet on her wrist, "Is all I need to stop your powers." Then, she pulled out her gun and pointed it down at her.

"Do it. Shoot me," She said, looking Alex right in the eyes and pointing between her own. "Right here."

"Alex! Stand down!" Kara yelled out as she walked up behind them, out of breath. Alex stared down at the young blonde for a few seconds. She couldn't help but see Kara in her. She stood up, pulling her up with her. "You're coming with us." She said. The girl gave her a dirty look, and was dragged away with Kara following close behind.
