Im gonna change the story a little bit
You are able to see angels actual wings in this story, not shadows but actual wings, cas' wings are still black, you can't always see them because they can disappear at times.
Kayla's wings are about 6 feet on each side of her, bigger than most of her brothers and sisters, Gabe's wings are gold
And this is kinda how they fold in (this is from Lucifer on Netflix👇🏻)
(And Kayla's wings are about this size👆🏻👆🏻)
