Kestrel is one of the MANY sons of ERIS.
He is a representation of the word REJECTION. and as he's cute, hes a horrible little fucking shit.
Horrible horrible awful bad bad seed..

Kestrel is smart, but doesn't let you know this.
He knows exactly what he's doing when he's being weird and freaking you out. He's letting you get comfortable with his stupidity. and as you think WHAT A HARMLESS CHILD. He will stab you in the back. Of course if theres something he wants from you.
If you dont have anything he wants then he's just pissing you off just to piss you off.
