Bridesmaids

Tom sat in his room overthinking his plan. In the living room the bride of his brother and her maids of honor were drinking. They were planning to leave soon for the bachelorette party except he would stop them. He poisoned the punchbowle on the table with his special mixture. He was a genius chemist although he was only 18. The girls wouldn't notice anything except a litte headache except he would us a special sound on them. A little high frequency voice command people normally wouldn't notice but with his mixture they would.
