Dannie nodded and grabbed a water bottle like a high school student would take to practice. She used an encryption spell and an anti-detection spell to change the letter and went to Jon's shop
"Hello" Jon said as she entered.
"Hi" Dannie said "I work for the wizard down at Spells R Us. He knows you have been chiding his business and he has sent me to kindly ask you to stop."
"Well I guess since you're asking nicely I can't refuse. Is that all?" Jon said
"No he also wanted me to give you a gift." Dannie said placing the water bottle down in the counter "He thought you might get thirsty during the day."
"That was rather nice of him" Jon said using a detection spell and it seemed clean. "I'll send him a letter of thanks"
Dannie left and Jon went to fill the bottle and drank from it.
Instantly his proportions changed to those of a cheerleader and his clothes did the same. His mind was left in tact though. Suddenly a note was attached to the bottle.
Dear Jenna (your new name)
Consider this a warning. Don't mess with me
Signed The Wizard
