Clue blinked at the compliment, and in the slight turn of his lips and brief flutter of pale eyelashes, there was something like a smile about his otherwise cold face. He did like Calla Potts, and he was quietly grateful for her amiable nature. He knew, however, that this really was just her nature, and there was nothing special about him in particular. She was destined to be a very popular girl, he reckoned, with tonnes of friends — but he would not inflict his strange friendship on her, and so he resisted his instinct to ask if she'd like to go and browse some Honeydukes chocolate together.
Now holding to his chest a paper bag containing his new robes, Clue felt in full exactly how important this moment was. He'd just bought something real and new for himself, with his very own money — for the very first time.
"Well... I had better leave you be." Those girls were starting to look at them again. "Thank you for your help, Miss Potts. I... appreciate it."
She wasn't sure she'd ever seen Clue Leverett smile before. It made him look... happier for lack of a better word. It made him look far more approachable. Without he just seemed aloof. "You look nice when you smile, Mr. Leverett," Calla noted with a grin of her own in return. The way she said it implied she thought nothing of her comment much like the way someone declared a fact that had no manor of question to it.
"Calla would do just fine, if you'd like." It wasn't technically proper, but when was a fourteen year old female quidditch player who love to play outside and be messy ever was? Besides, she had decided she quite liked the boy and was determined to be friends regardless of what he had to say on the subject. "It was a pleasure."
If Clue were socially equipped to respond in kind, he most certainly would've done so. He might've given another thank you, a smile, a gentlemanly nod of the head; all sorts of fine courtesies. That was what Miss Potts — Calla — deserved. But unfortunately Clue was just Clue, and he tilted his head slightly at the compliment, and at least managed to recognise the friendly exchange of first names. "Clue". She could call him that.
And then he let her leave for Honeydukes while he turned and went in the opposite direction. He held the folded, wrapped new robes delicately, as if they were something precious to him. This package was the first thing he'd ever bought with his own coin; and thus, perhaps, a symbol of a hopeful future.
