Alastor’s shadow is quite alot like it’s owner. So, it always has a creepy smile when it’s out. Since it’s a shadow, it represents Alastor but is at the same time kind if it’s own person. It looks like a normal shadow version of Al, but it can also stand, walk, interact with people, and talk. But it doesn’t often talk. He enjoys what Al likes and feels the same amount of respect for him as he does himself. Yes. The shadow has feelings, shadow lives matter too.
