When you call Jack Jack to save your seat, and even if you’re not there, the seat is still yours, like it’s some kind of magical seat spell.
I called Jack Jack and saved my seat, and my friend had to sit in the back.
I called Jack Jack before class, and the seat was still there when I came back.
I called Jack Jack in the lunchroom, and no one dared to take my seat.
