Her answer, here, is cautious: "I trust his judgement." Perhaps more than her own, on occasion, where Charles is concerned; if Severus had seen fit to dismiss him from the department (a drastic step, and one she had balked at when she first read the message), then...then she hesitates to question him on it. He had reason, presumably. She can see it for herself now, here. "And I've not forgotten your reluctance, before."

When she'd come to bully him back to work and it had gone-- slightly differently than planned, if not displeasingly so. (Quite the opposite. It had gone exceptionally well, thank you for asking.)

"Would you be so much more enthusiastic, were I to take my part as I did then?"

She doubts that very much.
