Amelia had known Trowa would have an opinion, with him being an artist or whatnot, and she was pleased that he at least seemed to give the question some thought. When he pointed his pencil toward the self-portrait and explained his reasoning, Amelia looked down at the portrait in her right hand with the same critical eye Trowa was giving it.
"I agree. Courbet it is, then," Amelia said, setting the country scene back onto the pile among its brethren before turning to survey the room at large. All the walls were empty, and none of her classmates seemed to be competing with her for the best classroom real-estate, so she had enough time to determine that the right hand side of the room between two windows was the proper final resting place of the wide-eyed painter.
The Ravenclaw girl picked up her wand and strode over to the wall. She held the picture against the wall with her left hand while giving her wand a few turns with her right hand. "Epípedo!" Amelia said firmly, conjuring a small rectangular image with yellow liquid and a small air pocket suspended in it. The image rested atop the picture's frame and Amelia adjusted the photograph until the air pocket rested just in the middle. Amelia's OCD would never have allowed her to stick a crooked picture permanently to the wall.
Satisfied that the picture was level, Amelia ended the previous spell and stepped back to arm's length to cast the permanent sticking charm.
"ee-TER-nus NEC-to," Amelia said, waving her wand in the appropriate fashion as a snake of white light slipped out of her wand and behind the photograph. She left her hand holding it up for a few seconds until she was brave enough to check to see if it had worked, and was relieved when the photograph didn't fall when she stepped away.
That could have gone much worse, Amelia concluded, giving one last appraising look to Gustave before turning to rifle once more through the box of portraits at the front of the room.
