Rodolphus watched his younger sibling go trotting off. Once Rabastan was inside he turned his attention to the young seeker and the team captain. He could not help but smile at how Regulus was not only hanging on Lucius but completely oblivious to Lucius' not so pure intentions toward him. For a moment he contemplated helping the young Black out. In the end he decided that he would rather have Lucius paying attention to Regulus than Rabastan. Sure he thought of Regulus as a little brother but unlike Rabastan he was not actually blood. So Rodolphus felt no remorse in leaving his brother's best friend in the clutches of a wolf.
