((I edited this a little after forgetting Nurse Miriam, plus I headcanon that Miriam and Jacq are siblings, BITE ME))
The teachers were panicking. It was after school hours, but somehow, you turned into a six year old, in front of the teachers, They were all shocked, and had no idea what to do. Some of them were running around, a couple were laying on the floor, confused as heck, and some of their Pokemon were just watching the chaos, oblivious as to what was happening.
Jacq: Panicked, running around the room "WHAT DO WE DO, WHAT DO WE DO, WHAT DO WE DO, WHAT DO WE DO, WHAT DO WE DO, WHAT DO WE DO, WHAT DO WE DO, WHAT DO WE DO, WHAT DO WE DO, WHAT DO WE DO, WHAT DO WE DO, WHAT DO WE DO, WHAT DO WE DO, WHAT DO WE DO, WHAT DO WE DO, WHAT DO WE DO, WHAT DO WE DO, WHAT DO WE DO-"
Nurse Miriam was trying to calm Jacq down.
Saguaro: "How did this happen to one of our students?!"
Dendra: "Okay, calm down, don't freak out, don't freak out... GUYS I'M FREAKING OUT-!"
Clavell: "Did one of the student's Pokemon do this..?"
Tyme: "Well, if a Pokemon did cause this, was it an accident?"
Salvatore: "Was it a Hypno or something?"
Hassel: "If it were a Hypno, then this teen-turned-kid would be acting like a kid, not looking like one."
Tyme: "But I don't know any students here that have a Hypno. I've seen a few with Jigglypuff or Drowzee, but I've never seen a Hypno in this academy."
Jacq was still running around, making a lot of confused and panicked noises.
Saguaro: "Maybe Celebi came here and replaced the student with their past self?"
Clavell: "Well I've been watching the cameras the whole time, and not once did I see a BIG flash of light, or any traces of a Celebi."
