When Severus had expressed extreme caution to Lily, he certainly did not mean this. Granted it had been later in the evening, however, his father was just taken into custody after being found rummaging the outer perimeter of what was known to many as the rather dreary Spinner's End. The fact that she was attempting nearly the same feat was equally puzzling as it was worrisome to the dark wizard. Severus quickly retrieved his wand from his coat pocket to gently pull back the curtains looming over one his front windowpanes. He was pacing; looking for something to bail him out of this sudden cesspool of negative thoughts that began to relentlessly produce by the minute. It was interesting to see himself this way—caring about another when this time his own life was on the line. While he appeared to have entertained the strong presence of the Dark Lord since graduating Hogwarts, Severus certainly had his fair share of reserves as did any other Death Eater. In fact, if it hadn't been for that same innocence which caused Lily to come to Cokeworth that night, he most likely wouldn't have been as sympathetic as he was to what was now known as the ‘Filth’.
Severus motioned toward the side-door, the one Lily often came to during their childhood when she happened to be in search of him. It was often locked when Severus was young, which made it all the more unpredictable when it came to identifying an escape route. “You are insane to have brought this chil—” started Severus in a low whisper, as he silently slid the door open, “Harry, this infant of yours. If you are planning to leave, I don't know how much time you will have. They have taken my father and have sanctioned patrols in this area for the remainder of the night.” he would have gently closed the door should Lily, clutching her child, have passed through quietly. It wasn't until Severus took notice of her artificial features that he pondered whether or not the person who he had let in was truly Lily Evans. Through the exhaustion and exceptional charm-work, Severus knew that it was.
“Take a seat, if you must. I'm sure you're exhausted.”
