He watched as Hermione narrowed her eyes slightly at the pumpkin juice, Severus stopped watching Harry for reactions a while a go, the boys mask was surprisingly firm, Hermione still had issues totally concealing her initial reactions and emotions. Harry secretly met her eye and seemed to have a understanding and Snape watched as Harry leaned across the table and took a dinner bun from a tray in front of the twins who were beside him, Severus felt his eyes widen, idiotic boy! It was obvious that the twins had done something to them, but as Harry’s face blew up and his hair started flashing colors Snape got it, everyone turned away from Hermione who discreetly vanished her drink before replacing it with colored water similar enough to pumpkin juice to pass. She then proceeded to spit it out as if she was laughing when Harry’s nose bulged out, and everyone turned to her as her drink seemed to have sprayed directly on Percy who spluttered standing up embarrassed and angry, everyone started laughing even harder, and those who weren’t were fawning over a "choking’ Hermione and then Harry did as she did. Perhaps these two had a chance, Severus thought as he hid his smirk behind his glass. He knew one thing for sure, he was sure glad he updated their bracelets their first day to grow cold when a potion is in intended food, and vibrated when someone casted any compulsory magic within 20 feet of them. No one noticed the disillusioned bracelets on their wrists.
