Lucius nodded his thanks as Severus returned with the drinks. Of course there were things he wanted to ask, as he knew Narcissa hadn't told him everything. Things about himself, about his wife, about his relationship with his son. Also there was Severus himself. He had made the unbreakable vow to protect Draco...but to what gain? Of course, he was a close friend of the family but to risk everything...there had to be more to it. Lucius took a sip of his cognac, welcoming its tingling warmth.
"I'll speak plainly, Severus, if I may. Out of character perhaps, but, I think we're passed that by now." Lucius gestured to their surroundings in mirth. "Tell me about the unbreakable vow. I only know what Cissy told me, but I can't help but feel there was more to it."
