Alex paced back and forth in front of the hospital as she waited for Kara; she walked quickly towards her when she spotted her.

"Why did you want me to meet you here?" she asked confusion written on her face.

"It's time we got some answers," Alex told her as she walked inside. She immediately spotted Lena's doctor as she walked towards him quickly.

He looked up startled as the two women walked towards him, "can I help you?"

"I'm agent Danvers; we need some information on one of your patients Lena Luthor."

"Do you have a warrant?" he asked as Kara slipped pass and went into his office.

Alex continued to distract him as Kara looked for Lena's file.

She knew there was something Lena was keeping from her and she had to figure out what it was, she finally noticed a file lying open on the desk, it simply read Lena Karen Luthor, curious Kara sat down and began to read.

Alex began to worry when she didn't see Kara sneak out.

"Agent Danvers is there anything else you need from me?" the Dr. asked as he opened his office door.

Alex peered around him to see it empty, "no sorry to keep you," she told him as she gave him a tight smile before racing out of the hospital. "Is Kara here?" she asked Winn as she arrived at the DEO.

"I think she went to the training room," he answered not looking up from his computer.

Alex ran there as she entered to find Kara in the middle of the floor, tears streaming down her face, "what happened? What did you find out?"

"She's dying," Kara whispered.

"What?" Alex asked as she kneeled down in front of Kara.

"The file said she was poisoned, she doesn't have very long left, she broke up with me to keep me from finding out," Kara sobbed.

"Kara she loves you, she is probably just scared," Alex assured her as she pulled her into a hug.

"We could save her, we have to," Kara sobbed.

"It seems she doesn't want to be," Alex told her.

Kara pulled away as she wiped her eyes; she stood up and super sped out of the room.

"Shit," Alex mumbled as she followed.

Winn looked up as Kara appeared beside him, "what's up?"

"I need you to track Lena's phone."

"Kara this isn't right," Alex warned her but Kara held her hand up silencing her.

"Do it," Kara demanded.

Winn looked between the two sisters before typing away, "Her phone is off."

"Damn it," Kara mumbled as she super sped out the window.

"KARA!" Alex screamed causing several agents to look up startled.

"What's going on?" J'onn asked as he stepped up beside her.

Alex signed as she told him everything.

"Oh my God," Winn said as he blushed at being caught listening.

"Winn research every possible poison you can, we have to save her," Alex ordered him.

He nodded as he got to work.

Kara landed with a thud outside of Lena's cabin, she used her x-ray vison frowning as she found it was completely empty as if she had never been there. She entered the empty cabin looking for any clues as to where Lena could be, she found a notebook lying by the fireplace and picked it up, it appeared to be a journal Lena had kept talking about her illness, how much she misses Kara and how she hated her mother for what she did to her. Kara shook with rage as she reread the last part about Lillian being the one that poisoned Lena. She clutched the notebook to her as she flew off.

Everyone looked up as Kara landed with a loud thud. "Find me Lillian Luthor," she told Winn her voice eerily calm.

"Did you talk to her?" Alex asked fear in her voice at the look on Kara's face.

"She wasn't there," Kara told her as she handed the notebook to Alex.

"Found her, she is holed up in an abandoned building on eight street," Winn told her.

Kara's eyes narrowed as she flew off.

"OH GOD!" Alex exclaimed as her face went pale.

"What is it?" J'onn and Winn asked.

"She's going to kill her," Alex said as she began barking orders at agents.

J'onn took the notebook as he and Winn read it.

"Poor Lena," Winn whispered.

"My God," J'onn said sadly.

"We have to get there in time or she is dead," Alex told them.

"Let's move out!" J'onn yelled as they all filed out.

Lillian was looking through a microscope when Kara burst in startling her.

"Howe could you?!" Kara said angrily as she strode towards her.

"Do what dear?" Lillian asked with a smirk as she stepped away from what she was working on.

Kara super sped towards her as she grabbed her by the neck as she lifted her off the ground.

Lillian gasped as she clawed usually at Kara's strong arms.

"Do you really hate her that much?" Kara asked as she squeezed tighter causing Lillian to gurgle as she struggled to breathe.

"Kara stand down," Alex demanded as she and a team arrived followed by J'onn.

"She needs to pay for what she did," Kara said a look of pure hatred on her face.

"And she will but not like this," Alex pleaded with her sister as she stepped closer.

"She killed her Alex," Kara sobbed as her grip loosened.

"We will find her," Alex told her as she wrapped her arms around her sister who dropped the woman before turning into her arms.

Lillian scrambled off as agents rushed over.

"She's gone," one of them said.

"Find her," Alex demanded as she held Kara.

They nodded before splitting up and searching the building.

"Hey it's all going to be okay I promise," Alex assured her sister as Maggie walked in.

"Hey I got your message," she said as she gave Kara a sad smile.

"They are still searching for her," Alex told her.

"We will help," Maggie said as she barked out an order through her walkie.

"Thank you," Kara whispered her voice hoarse from crying.

"Anytime," Maggie told her with a smile as she went to join the search.

A plane landed in Ireland as a women stepped out, she then stepped into a taxi as it took her to a small house in the middle of the mountains. She stepped out to see Lena planting some flowers; she didn't seem to notice the women as she wiped her hands before walking back inside.

"Hello Lena," Lillian said with a sinister smile.
