Marnie wasn't unexpected, really. Cass had figured that with the way he spoke to Sable over the forum, that she'd have some sort of back up, and he fixed his intense, darkly cold stare on the mother first. "Ms. Harris, Please, help yourself to whatever is in the kitchen. This is between the three of us." His voice was level and chilly in tone. He wouldn't start talking to Sable until Marnie was out of the room, he decided just then.
He faced Sable and stood still, arms crossed. He was practically staring, with an expression that was only reserved for two things - people who had hurt him to the extent where he actually got pissed, and people who had hurt someone close enough to him where he would get pissed off enough to get into a mood that was not particularly sane, rational, or levelheaded. It never occurred to him, until just that day, that perhaps the Wartooth anger did pass down to him.
