Ohhh, so this all made perfect sense now! Sophie had been wondering why the professors couldn't go ahead and do the charm. It made perfect sense, though, that they needed everybody on board to do the charm, so that the effectiveness was much greater. Right. Got it, Professor.

So now it was time to practice the incantation and wand movement--separately. Sophie always did it separately anyway, because...who wanted to practice a brand new charm the first time without being sure of themselves? Not her. With her luck, she might catch herself on fire or something.

Sophie kept her wand in its holster so no such accidents could happen then began practicing in the incantation. "Caelum Saepio," she said aloud. "Caelum Saepio." Then she broke it down to make extra sure she was saying it the way the professor did. "CAY-lum - SAY-pee-oh. Caelum Saepio."
