This is weird to think about, just cause I have nothing to go on as to who/what the spirit is. We know they don’t have to share the same personalities like Isaac and Rain-Cloud. But they could be similar like Isabel and 8-fold.

I have a feeling that spirit Spender has is affecting his eyes somehow. That explains why he is constantly wearing sunglasses, even inside and at night. It could be like a cyclops thing where the spirit is possessing him, giving him ghost laser eyes that he needs the glasses to control. Or the spirit is possessing exactly 1 eye so Spender needs the glasses to cover up. Or the spirit is just possessing the glasses themselves, so easier to carry.

I think that Spender’s spirit is giving him the power to be “extra”, so they are going to be super out there, bubbly to the point of insanity, extravagant. Something like that. And that whatever he “sees”, his powers can bring it to life. Like controlling light to form those spirit shuriken stars.

That is all that I can think of. I don’t have much else to go on.
