DESCRIPTION
a couple of things here:
Gaz's eyes are red as a symptom of gorging on blood. It's also evidence of Graves' control over him.
Valeria's paralysis stare doesn't work on Rudy's spectral dogs because they aren't technically living organisms, just spiritual extensions of himself, so he can look through their eyes at her with no repercussions.
Soap hasn't been shown yet, but he does have a role in all this.
