Fallen angel brothers

What did you do!?

After having fun talking with Lucifer, Castiel felt a little better but he still felt pain in his back for his flying mistakes back at the training. It was just 10 days before his finals. So Castiel decided to walk around and maybe sat at his favourite bench at his favourite garden. 

"Hellllooo, Castiel. What are you doing here? You're supposed to be resting by now", "You're supposed to be sending mails?". Both chuckled as Gabriel sat beside to his little angel. As the wind started to blow, Castiel breathed in as if the Garden was always having the best weather. "Casteil, I want you to do something for me?". Castiel looked at Gabriel curiously. "You're going to remember this for the rest of your life ok Cas? I promis that I always be there for you Castiel, no matter what it cost. I want to watch you grow up, and I want to protect you because you're my little brother",and it made Castiel tear up as he hugged Gabriel and thanked him."Thank you or should I say Gabriel who always throw diapers to Lucifer?"

Gabriel jumped out and he pointed to Castiel,"How- How on heavens you know that?". Castiel laughed as he said" "Lucifer told me yesterday wen you were on duties. Gabriel blushed as he tickles Castiel and Castiel struggled to make him stop, then the bench start moving back as Castiel adn Gabriel fell. Unfortunately, Gabriel made it worse. "My back!", Gabriel was in shock because he didnt knew Castiel was injured on his back. "Cas? Oh no, I'm so sorry, dont worry, I'll put you back on your bed", Castiel couldnt bear the pain as he keep screaming even all the garrisons of the heaven heard it, and now he started to cry because he couldn't hold the pain since the impact was hard.

Few hours later, Gabriel went back to Castiel's room feeling guilty for the incident happened back at the garden,"Cas? You here buddy?". Castiel didn't answered as Gabriel feeling more guilty than ever, "Come on Cas, I'm sorry ok? I was just having fun with you. I'm a bad brother aren't I?"

Castiel suddenly giggled as he looked at Gabriel."It's ok. At first it was bad, but now I guess I wont go anywhere". Gabriel smiled as he sat beside his brother who he sworn to protect.
