Gui Song

"By any chance are you Severus?"

Out of nowhere the old man entered inside the room and barked his question. 

Severus calmly analyzed the old man. He saw how serene his face looked despite having an aged face. The old man sat beside Severus as he elegantly started to brew tea for himself. Severus' face twitched when he saw that the old man was only brewing tea for himself.

"Yes I am"

"Good Good"

"...."

Is there anything good?

Severus was confused. Nevertheless, how stupid he felt about the old man he didn't dare to let his guards down. If a complete stranger like him knows about him then his worries aren't superfluous. 

The old man who was sipping his tea seemed to understand Severus' queries thus he put his tea down and thought about giving an explanation.
