The light brush against him as Lupin opened the door was felt more accutely than it objectively should've been. But not many touched Severus, and he didn't touch many, as it was, so that was only natural.

"I hardly think he'd believe me. That man has an uncanny ability to know. And it would probably only serve as an incitement to send me here more often. I suspect he enjoys pitting us against each other." He chuckled lightly.

"I will see you Sunday I presume, since Dumbledore has given you enough work to last until then." Severus nodded lightly again, resisting the urge to shake Lupin's hand in good bye.

Why do you want to touch him?

"Good night, Lupin." He stepped past Lupin, once more briefly enveloped in the warm scent before he was outside in the cool evening air. Yes, it was time to go home.
