Pinkie's POV

I was skipping around Sugarcube Corner, humming a song happily, when suddenly, somepony grabbed me out of nowhere! My eyes widened. I looked at him - or her -, who was covered in black, probably to hide their face. "W-Welcome to Sugarcube Corner! How m-may I help you?" I asked nervously. "I'm not here for cake." They said, and by their voice I know it was a mare. She reached into her pocket and pulled out a picture of Rainbow Dash. "Do you know this pony?" She asked. I shakily nodded. "Y-yes, that's R-Rainbow Dash." I said. "I need you to get rid of her for me." She said quietly. "W-what do you m-mean?" I asked, not sure I heard her right. "Kill her, or I kill you." She stated bluntly. "But she's my friend! I-" I began but she cut me off by gripping me tightly. "Do.It." She said, like the kind of mare who doesn't take 'no' for an answer. I nodded with tears in my eyes. "Yes m-ma'am..." She nodded. "Good. I'll be back in a week. If it's not done, you won't see the light of day ever again." She said and with that, left. I sunk to the floor, confused. I really didn't want to kill Rainbow Dash, and I'm not going to! I have to do something...but what? My mane deflated as I thought. Suddenly I got an idea, like a light bulb went off in my head. I had a fool-proof plan! First, I need to talk to Rainbow Dash...
