Voldemort's POV
10 years later I met you again. You wanted to save Potter and I enjoyed seeing your power. Finally seeing emotion in your eyes. It was determination. You wanted to stop me, to save Potter so I decided not to make the same mistake twice. I didn't kill him, I only played with him so you could take actions and help him.
4 years later I broke into Hogwarts on Christmas night and disguised as professor's familiar – kneazel – watched you. You watched as a hawk that your Slytherins behaved with manners, got angry when Dumbledore popped cracker and replaced his horrid violet hat into more hideous pink. When he tried to make you pop another one, you fled to your dungeons.
I fallowed you and saw that in large living room roared fireplace, there were several socks hanged on fireplace and big, beautiful Christmas tree was in the corner. You were lying on the black leather coach and sipping Firewhisky. I silently sat in nearby armchair. You opened eyes and recognition was in them. I looked like Tom Riddle in his thirties again.
-What should I call you? - You asked in beautiful silent voice. I extended my hand and you gave me glass of Firewhisky.
-Call me Tom. I have the same goals but I don't want to kill innocent people anymore, wizards or muggleborns alike.
We sat like that, enjoying drink and silence. I watched you drinking and when you looked into my eyes I couldn't turn away. I missed those cautious brown eyes. I felt you getting into my mind and let it. I let you see my thoughts, wishes, past, everything but my love for you, dearest.
-I believe you, Tom. I suggest you to live in Forbidden forest or Shrieking Shack.
-No, I will live in Hogsmeade 27. ,, In your house, Severus".
-If you wish. You finished your drink and stood up.
-I'll visit you soon then.
Maybe it was alcohol, maybe simply desire but I stepped forward. You stood in the same place but fallowed my movements with narrowed eyes. I stood in front of you and put my hand on your shoulder. In your eyes was spark of surprise but you didn't move back.
-I have changed Severus. I wasn't happy the way I was earlier as well, so help me to change this world into a better place.
