Hmmm, so if the muggles just thought they were ghosts if they saw a witch or wizard performing magic, then why was it illegal to perform magic in front of them in the first place!? That made no sense! Though she so wanted to test her theories on the matter, and then blame it on Mr. French Man Charms Professor if she got into trouble.

However, the charm he finally told them that they'd be learning was actually a really interesting one. One that she could see herself using in the future for whatever purpose. Turning her gaze away from the fire for just a moment, she watched the wand movement and then...

OMG GAHHHHH! SHE WAS BLINDED!

No not really, but the fire light did become brighter, and then the shadows grew to counter the light. That was...interesting. Mentally repeating the incantation, the Slytherin took a deep breath, gaze landing on the lantern that appeared in front of her before pulling out her wand from her wrist holster.

...

"What do you mean, we're going into the Forest?" she asked, eyebrows raising in surprise as she STARED at the Professor. WHY!? WHY AT NIGHT!? WHYYYYYY!?
