In an attempt to make yourself less fearsome looking, Hour-Tales finds himself still very pumped up from the fight with the squirrels, the running through the trees, and the anger he felt when he saw this man. This adrenaline pumps through him so strongly, that even though he tried to make himself less fearsome, he became more fearsome. His eyes are more deranged, his claws more jagged looking, his fur more tussled, and his jaws slightly drip with saliva.
Perhaps this is when it occurs to soft paws, that this man does appear to be human, but seems unaffected by the delirium.
