She looked at the notes she saw he was pointing to the spell Incendio. It would be very useful in battle. "It says that Incendio is very useful for creating fires during battle to distract an opponent or singe your opponent" she said reading the notes. Walking over to the fire she tried to remeber a certain spell. "Aguamenti" she said and aimed her wand towards the flame. It put the fireplace out and she lit the tip of her wand for light so he could see "Lumos"

Better they practice on the fireplace instead of each other that could be dangerous.

"Ok now just try and set the fire on the fireplace" she told him.
