Is probably… that this just a big mistake of my part or something. But, unless someone explain me, Did you see? karkat is the only with no wings.
So this remain me, Do you remember, this character… angel, from x-men: The Last Stand? Well if you not, In the begining of this movie he (just a little kid) is cutting his wings because is afraid of what others could think.
So… I used that idea here.
