There was a knock on the door. Severus clenched his eyes shut, slamming a vial of unicorn blood on the table.
"Come in", he growled. The door creeked open slowly. Severus heared Dumbledore speaking to someone outisde before gliding in and shutting the door behind him. Severus held the vial up to his eyes, and without turning around he spoke
"Someday someone is going to be tempted to whipe that horrible smile right off your face."
"Yes, but people have far too much respect for me. I have a favor to ask of you."
Severus turned around and bowed extravently.
"Anything, O Captin my Captin."
"Exelent." Dumbledore clapped his hands together in glee.
"Miss Granger, would you come in please." he called.
Severus froze.
"I wasn't really agreeing to anything."
Dumbledore waved absentmindedly at him.
"Of course dear. Ah Hermione, here you are. Professor Snape has most kindly agreed to apprentice you."
