This was beautiful. Loved the imagery and emotions of the sparring session.

Aww I loved this! I can see them sparring together, especially if Gadreel had survived. His story broke my heart and I wish it had ended better for him. Reading a fic where he's happy and gets to be a brother was a delight.

I have to say that I enjoyed this little Gadreel story very much and I would like for you to write more of him in the future. I also think Castiel is great in here. You write very well.
Thanks for sharing. Take care.
