So...windows. Ella kept getting distracted by the thoughts of the house elves. She wanted to know where they were, what they were up to, if they were cooking delicious treats for other students somewhere. Frown. They were okay, yeah? ...Yeah.

Pointing her wand at the nearest dirty window the sixteen year old said, "Vitrumonia," before doing the waving motion over a small section as a test. Beam. It worked really well and the blonde was eager to see just how big of a section she could manage at a time. She continued on, waving and saying the incantation with concentration. It was impressive, how well this particular charm worked. The windows she was standing in front of looked good as new. They even sort of sparkled which Ella really liked. Hopefully no birds would fly into the windows thinking they were open, though. Meep. That wouldn't be good.
