Severus doesn't know but that the dark lord called him today, he is tired enough from dealing with everything, his work in potions, defense and double spy work is not easy. He has been very stressed and alone lately. The potions professor is upset and now he also has to take care of you, as if he wasn't already enough being a spy.

Severus didn't have the luxury of showing any emotion, he is cold as he looks at you "Follow me, pet" He doesn't bother looking at you, although he could use legilimency, he doesn't feel like dealing with this right now. "Walk" he commands You to follows him, he sighs. He is disappointed, why did you let them catch you? You were his favorite person, great...

Severus looks at you as You follows him "stay still. He takes you into his protective arms and makes you both appear in his house.*

severus just wants to protect you
