@wemadeemc0c0a liked THIS for a starter.
SEVERUS WAS ALWAYS CAREFUL TO AVOID THE DUNGEONS UNDERNEATH MALFOY MANNOR - aware that that was the place where the Dark Lord liked to keep his most important prisoners. He is also painfully aware that he knows some of the people down there --&& that there is nothing he can do to help that. But he could not ignore a direct command without rousing suspicion, so when his master tasked him with retrieving one of the prisoners he had no choice but to obey.
He keeps looks straight ahead the whole time -- careful not to let his eyes wander -- until he reaches the cell where Luna is being kept. Thick metal bars creak when he opens the door && scans the area, even if, as far as he knows, Luna has no cellmates.
❝ Miss Lovegood, you are required upstairs. ❞ he speaks slowly, still not directly looking at her as he undoes her shackles.
