Terry's heart went to Faustus, who was the perfect study of sullen misery. He knew that Severus would never do anything to physically hurt the boy, but he didn't have the same confidence about Severus' tongue. He saw the way Severus studied his son intently, but also the way he touched him so gently, and his heart lightened.
"Good night, Faustus," Terry said, kneeling to hug Faustus quickly, uncaring of what Severus would think. "You're welcome here anytime, as long as your dad knows where you are, okay?"
Ben moved closer and threw himself at Faustus happily. "Thanks for going to Narnia with me Faus! Next time we'll go to Hobbiton! Maybe your Daddy will want to come too!" He looked up at Severus and beamed, hugging the man's legs quickly. "I'm glad you have a little boy now, Mr. Bat Man. Now I can have a friend in the castle!" He hugged Faustus and then Severus again, and then climbed up Terry's legs so he was settled in his Daddy's arms.
Terry shot Severus an apologetic grin, and made a note to talk to Ben about appropriate behavior sometime soon. He had a feeling though, that nothing he said would ever curb Ben's natural exuberance, and he wasn't sure he wanted to. "Have a good night, and remember what I said Faustus." He smiled reassuringly at the little boy.
