Severus Snape
I can't believe Dumbledore uses an Unforgivable Curse on me. Forcing me to do his bidding. To steal My Lord's son.
My lord knows that I would only be against him under the influence of the Imperious curse (a curse that when cast successfully the victim losses all control and is willing to do the caster's bidding).
I found myself at My Lord's manor and without knowing what happened I had Harry in my arms asleep and Dumbledore next to me.

"Dumbledore, where are we going to but him?"
"Wool's Orphanage, he has no family outside the wizarding world. Let's just hope he doesn't turn out like his father."

I went to Voldemort the next morning to see him holding his son's black and silver blanket.
"My lord I have something to say that you might not like."
"What is it?"
"Dumbledore cast the Imperious curse on me and I was made to take your son. I don't remember where though. I am deeply sorry. I will search for him if you wish it."
Magic was rolling of of him in anger then he calmed down.
"I know the power of the Imperious curse so I will not kill you. Be when the time is right either you or Harry will kill Dumbledore."
"Yes my lord."
"When Harry arrives at Hogwarts report how he is doing, what house he is in, if he needs comfort you comfort him. In other words act like a father."
"Of course."
"Thank you Severus for telling me and always being there"
"Anything for the right cause."
