[If there's one constant trait Walter has, it's that he never backs down to aggression. Rather than flinching or clamping up defensively, Walter's posture, if anything, becomes more relaxed. He does not frown; he smiles.

Walter is no werewolf. Nor is he contaminated by any supernatural blood or curse or anything else that would explain away the behaviour. But, without question, there is something off about the smile that stretches across his lips as he matches Isaac's step forward.

Perhaps it's how his expression seems almost manic-- as though the idea of a confrontation is something to be excited about.]

Your eyes and your sleep hunting tell me a different story, puppy. Now run on back to your pack before you find out the hard way just who you’re trying to intimidate.
