Amycus stood in complete unison with his sister and bowed to the Dark Lord. Without saying another word to him he met Alecto's eyes and returned her nod. He let Alecto lead them out of the room as he walked beside Fenrir.
He couldn't help but smirk when Alecto had mentioned how they were familiar with where they were going. Immediately after Alecto had apparated he turned to Greyback and smirked.
"Try to keep up will you?" he was used to joking with the werewolf..but he didn't make a habit of it because he didn't want his throat ripped out. With that he vanished as well following his sister.
