To babysit her

"Simple, really." Emily said with a cruel smile, "We want to babysit you. Just like you used to do to us."

"That's all...?" Amy asked in confusion. "You're just going to watch me for a few hours and - "

"Oh, no." Theo chuckled darkly. "We mean exactly like you used to do to us."

"I'm not following..." Amy stated, gulping a little. Truthfully, she did have a feeling about what they meant, she only hoped that she was wrong.

"Oh, I think you are." Emily responded with a chuckle, "Remember when you were chaperoning my Sweet Sixteen and you showed the entire party my baby pictures?"

"Or the time when you invited the entire girls volleyball team, including my crush Cynthia, over to the house while I was in the shower?" Theo reminded, "And then when they arrived, you threw me out of the house and stole my towel, leaving me butt naked in front of them?"

All the color drained from Amy's face. Unfortunately, she wasn't proven wrong. Her two younger siblings actually intended on humiliating her beyond all reasoning for her pranks and bulling!

"Welcome to payback, Ames." Theo said with a smirk.

"Absolutely not!" Amy snapped, stomping her foot. "You are not babysitting me! You can just forget it!"

"Well then," Theo said, "if that's the case then we'll just go. Though don't be surprised if you find certain pictures on the internet..."

"No wait!" Amy screamed desperately, the little woman seeing the amused looks on her siblings faces. Sighing in defeat, Amy said, "Fine. You two are in charge. You two can," she gulped as she hung her head in shame and embarrassment, "babysit me."

"I knew you'd see it our way, Pipsqueak." Theo cooed mockingly, condescendingly ruffling Amy's hair as the little woman looked up and glared at her little brother.
