There is no me without you (a supercorp Fanfiction)

Chapter 37

Kara POV
Even though we just met these kids, they feel like family. It was amazing how Lena was straight into mum mode with the kids. It makes me think why Lena and I didn't come back with them. Casey must have guessed what I was thinking.
"Do you want to know what happened?" He asked in a small voice. My heart broke for the boy. He was trying to be strong for everyone. I nod my head. He pulls me out of the room. I looked at him as to ask him why silently.
"I don't want my sisters to relive it." He said as he closed the door to the training room. That boy has the work on his shoulders. I want him to be able to be a teenager. He shouldn't be put into this mess.
" Casey, you don't have to be strong. I will protect you no matter what!" I say trying to comfort my son. Well my son from another earth.
"You can't save everyone. You trained me to help you keep my sisters and mummy L safe. Your training saved our lives. But I couldn't save everyone." He said bursting into tears. I wrap him up in a tight hug. This poor kid! He sobs into my shoulder. I held him close whispering to him that's it's ok, that I'm here and the he is safe.
"Baby what happened?" I asked gently.
"Uncle Lex, he killed mum L, with the bond in place you died too" he choked out.
"Where was I at the time?" I ask softly.
"You has found a way to stop uncle and to stop the hate uprising against the aliens on our earth. You had to go back to DAX-AM. Through the phantom zone." He kept sobbing his arms wrapped around me holding me tightly like I was going to disappear. OH RAO! The conclusion room was right?! Oh rao I need to fix this. I won't leave my kids or my Lena!
"What did I need to fix it?" I ask. My brain is racing through everything I could remember about DAX-AM. "What can stop this from happening here?" I ask. My mouth is not catching up with my brain. I have a million questions.
"A dark blue stone. I can't remember what it's called. But you said it came from krypton. You said because of the way krypton exploded there maybe still trace amounts on DAX-AM." He whispers. I'm thinking hard. What could it be? That's when it hits me. LENA'S NECKLACE!
"Casey, I have some here." I say softly.
"Really? You didn't have any on our earth. Maybe you and mummy will be ok here after all." He says in a small voice. He was like a small child. He was so broken, so scared. All he wants is his parents. I gently kiss him on the top of his head.
"Baby, you did everything you could. Don't blame yourself." I say to him sincerely rubbing soothing circles on his back. He tightens his hold. I will not let this boy or his sisters down. I will protect them all.
