Severus Snape opened his door, stepped out, and very nearly tripped over the baby on his doorstep. Startled he stopped. Surely he had been mistaken. But when he turned around and stared, the bundle had not disappeared. There. Was. A. Baby. On. His. Doorstep. A breeze ruffled the baby's hair and his eyes narrowed when a lighting bolt scar was revealed. There was a Potter on his doorstep.
"Albus!" He ground out through gritted teeth.
Reluctantly he scooped up the sleeping bundle, restrained himself from slamming the door as he pivoted back inside, and deposited it on the table. He stalked over to the fireplace and floo-called Albus Dumbledore.
"Tell me this is some sort of a joke."
"Why Severus! How delightful to hear from you! How have you been, my boy?"
"Don't you dare! There is a Potter on my kitchen table!"
"Indeed?"
"Don't play dumb with me Albus, we both know you put him on my doorstep--what I can't possibly conceive of is the reason why!"
"The boy is an orphan now, Severus; he'll need someone to care for him."
"And you give him to me?!"
"I have absolute faith in you, my boy."
"Are you trying to get me killed?"
"Now, Severus, there's no need to get dramatic."
"It wasn't dramatics--you know the type of company I have been keeping."
"But there is no more need of that now...Oh would you look at the time--I really must be going..."
"Don't you dare!"
"I'm sure the two of you will get along splendidly!" With that, Albus Dumbledore's head disappeared from its spot in the fireplace.
"Albus! Albus get back here!"
A noise drew his attention to the table. The boy was awake. And looking at him with startling green eyes. Lilly's eyes.
Severus Snape turned back to the now empty fireplace and hissed, "Damn it, Albus!"
