River decided she didn't want to lose track of the investigation too much...

She put her phone back into her pocket, after making sure it was in 'silent mode', and walked to where Fonsus was. 

"I wonder what would happen if... Say someone did a charm to cover up damage... and you broke the charm somehow. Would, like, the stuff fall apart again? We haven't learned much about [i]undoing [/i]charms, just making them." Not that she had luck with either. 

"A repair charm will make the thing [i]look [/i]good as new... But maybe it's not actually fixed." She tilted her head. 

She frowned a little. She didn't like that thought. Magick doesn't really fix things. She touched her sternum where her charmed-necklace had settled under her sweater.

"In class, my charms fall apart [i]all[/i] the time after a few seconds." She bit her lower lip, thinking.

"Is that the difference from transfiguration maybe? Transfiguration you're, like, changing the matter itself. A charm is, like... Adding something or tacking magick on. If that's the case it can come off, theoretically, a stubborn sticker."
