Rab shook his head. "You don't need a reason... but I'll give you one anyway," he said, "This man tried to interfere in our cause. He actually thought he could take me. He tried fighting me, then he ran like a damn coward. He's not fit to even be here. But I've saved him... and now you get a chance to avenge a wrong that was dealt to me."
He smiled at Guilian's urge. "Yes... I can feel that. It does want you to lash out," he said, "BUT... now is the time to show it who is in control. I want you to torture the Muggle... but slowly. Start small... let the dark be pleased by the screams it will hear. Sometimes, the quick kill is needed. But you must show it that working slowly and deadly is so much more appealing."
He stepped away, but kept near just in case. "Now... take your wand... and work SLOWLY."
