As Eliza sat and watched Alex play with some toys, Kara entered the room, her Supergirl uniform torn.
"Kara? What happened? Are you okay?" Eliza asked.
"I'm fine. Just have less love for rocks." Kara said waving off her concern as Alex stumbled over to her. "Hey you." Kara smiled reaching down and picking Alex up.
"Kara hurt." Alex said gently prodding at one of the tears in the uniform.
"I'm fine." Kara said hugging her. "How are you?"
"Bored." Alex complained.
"How can you be bored with all these toys?" Kara asked. "How do you even know the word bored?"
"I think you may be expecting a bit much if you think she'll answer that." Eliza said as Kara put Alex down. "Are you sure you're okay?"
"I'm fine." Kara assured her. "How are the tests going?"
"We ran into a problem. Winn is recalibrating." Eliza explained.
"For the love of Rao." Kara said hearing the message from Vasquez over her radio. "I have to go."
"No." Alex said defiantly as she grabbed hold of Kara's leg.
"Yes." Kara said lifting Alex up and walking to Eliza and trying to hand her Alex.
"No." Alex said as she clung to Kara.
"Wow, that grip is strong." Kara said. "And I feel a little guilty about this." She added before tickling Alex just below her rib causing her to let go. Taking the opportunity she handed Alex to Eliza and left.
"No." Alex complained as she started to get upset.
"She'll be back soon." Eliza said hugging her.
"Kara hurt." Alex complained.
"She's fine." Eliza said, hoping she wasn't lying. "Why don't you have a nap?"
"No." She said defiantly.
-00-
"How is it going?" J'onn asked.
"Bringing back memories. Right now she is refusing to sleep." Eliza said. "Even though she can barely keep her eyes open."
"Looks like she is not the only one." J'onn said picking Alex up. "She's worried about Kara. She is projecting her concern." He added before looking at Alex and commenting. "Always the big sister aren't you?"
"Any closer to reversing this?" Eliza asked.
"That's why I'm here. Winn has made a break through, but wants your opinion on something. Go talk to him, I'll look after Alex."
-00-
"Damn it." J'onn said as he saw Alex totter round the command room. "How did you get out?" He said more gently as he lifted Alex up. In response Alex reached out for J'onn's ear and started playing with it. "Let's get you back to your play room."
"Maybe we should put Alex in a cell." Winn said. "Hear me out...she is escaping from everywhere so we could use her to test the security."
"Do you want to be the one to tell Kara that you want to lock Alex up in an area full of aliens who want to kill her?" J'onn asked.
"Perhaps you should put her in the sparring room, it is kind of a second home for her." Vasquez suggested before seeing J'onn sharply turn to look to her causing her to add a, "Sir."
Silently J'onn turned and left the command room and headed to the sparring rooms. Opening the door he entered and looked round for danger. "At least there are no sharp edges in here." He said before asking Alex. "Are you hungry?"
"Kara." Alex said.
"Will be ba-" He started only for Kara to walk in.
"I'm right here." Kara said approaching them. Seeing Kara, Alex immediately held her arms out. As Kara took Alex off J'onn he asked.
"You okay?"
"Next time I take a sheet of paper with me."
"Why?" J'onn asked.
"Rock, paper, scissors. I'm tired of being the scissors." Kara said. Not knowing what she was talking about he decided to change subjects and said.
"Speaking of tired, Alex needs to sleep."
"How do I make her sleep?" Kara asked.
"Try singing to her." J'onn said leaving.
"I can do that." Kara said looking at Alex. "But what to sing?"
-00-
"Why are you singing food jingles to Alex?" Winn asked as he entered the room ten minutes later.
"J'onn said I should sing and I froze. I couldn't think of any Earth lullabies all I could think of was Chicken tonight and Dr Peppper, then Folgers. So I started singing all the jingles I had ever heard and Alex calmed down so I kept going. I think I have done every McDonald's jingle from the last ten years and now I am sooooooo hungry."
"I'd offer to swap, but Alex won't like that. But I can bring you food." Winn offered.
"Thank you." Kara said.
"Why don't you just sing 'Let it Go'?"
-00-
When Eliza, Winn and J'onn entered the sparring room an hour later they saw Kara and Alex fast asleep.
"You want to leave them?" J'onn whispered, but the noise was loud enough to wake Kara.
"Hey." Kara said sleepily.
"We're ready." Eliza said.
"Will it work?" Kara asked.
"We hope so." Winn said.
"Hope?" Kara asked eyes wide. Her voice loud enough to wake Alex, who started to cry. But seeing Kara she quickly settled again.
"The technology is beyond anything we fully understand." Eliza said.
"But you used it on me." Kara reminded them.
"But you are practically invincible." Winn reminded her.
"So we shouldn't use it on Alex?"
"We have to. We don't know if staying like this will cause long term damage." J'onn reminded her. "Let's get her to the infirmary."
-00-
"What happened?" Alex asked when she woke up in the DEO infirmary.
"Alex, you're okay." Kara said hugging her.
"Shouldn't I be?" Alex asked before seeing her mother. "Mom? What happened?" She asked completely confused.
"You don't remember?" Winn asked.
"If I did, would I be asking?" Alex countered.
"No."
"So what happened?" Alex asked.
"Do you remember last year I got changed into a baby?" Kara asked.
"Yeah."
"Well now that's another thing we have in common." Kara said.
"What?" Alex asked.
"Don't worry, I have so much video evidence." Winn said. "Backed up on several different servers." Seeing the glare Alex was giving him he added. "Leaving now."
"The joke's over. What really happened?" Alex asked.
"We're telling the truth." Kara said. "If it helps, here are some videos and Hamilton's report." Kara said handing her a tablet.
"Wait you let Mon-El look after me?" Alex asked after several minutes when she saw the video of him playing with her.
"He was a natural." Eliza said. Seeing Kara pull a face Alex grinned.
"What?" Kara asked.
"Mom now sees you as her best chance of grand kids and she won't let this go." She then realised someone was missing and asked.
"Does Maggie know?"
"No. I remembered how weird it was for James and I, so we didn't tell her."
"Thank you." Alex said.
"Are you sure you're okay?" Kara asked concerned.
"I'm fine."
"What about your knee?" Kara asked.
"My knee?" Alex asked confused.
"You tripped and I couldn't catch you and you scraped it. I'm sorry."
"It's fine." Alex said still trying to get her head round everything.
-00-
"Hey." Maggie said when Alex opened her door.
"Hey."
"Everything okay?" Maggie asked. "You went silent running on me."
"Yeah, sorry. I couldn't use my phone." Alex said.
"I saw there was a giant rock monster on the loose."
"Rock monster?" Alex asked.
"Kara seemed to have a rough time. Looked like she got pretty banged up. She okay?"
"She got hurt?" Alex asked concerned.
"You didn't know? So you weren't helping with the rock monster?"
"No."
"Then what were you up to?"
"You wouldn't believe me." Alex said as she sat down frowning.
"Go see her if you're worried." Maggie said.
"She's fine." Alex said.
"Yet you are frowning."
"I just have a really weird craving for McDonald's and a Folgers coffee." Alex said.
"You don't like Folgers." Maggie pointed out.
"I know. That's why it's weird." Alex said. "But then again, compared to everything else today, maybe it's not that weird."
