Long Lost

"You know what we came here to do. What needs to be done, it's the right thing." A whispering voice says sympathetically.
"Yes, I know what the prophecy says. But I cannot accept the fact that she's a killer so... try it again." Another voice says back, this one male, almost sounding defeated. However, it's almost as if he wasn't trying to whisper back like he wanted me to hear him.
The next thing I know, I have a massive headache and my ears are ringing. I don't dare look out my window, scared of what I'll see. The headache starts to diminish but my ears still ring.
"She's fighting me." The girl, whisper yells. I don't even think they're trying to be stealthy anymore.
"Well, fight back, we need to know if it's actually her," The male voice says at regular volume now.
I rub my temples, attempting to ease the pain, nothing seems to be helping though. Then I hear the loudest scream that I've ever heard and probably ever will hear. My head pounds and my ears ring as if a bomb just has exploded right in front of me.
Then, all at once, it's gone, the pain, the ringing in my ears, and the voices. Leaving me to wonder what this prophecy is, what they're here to do, and here's the big one, why I can't remember some pieces of what they said.
