"Oh -- nothing", Adrien chuckled, "it's just -- uh -- I -- this is going to sound really weird, but -- it's weird to see you having -- well -- legs".

Valerion folded his arms; his face twisted into a silly smile. "What, you thought I had wheels?".

Adrien burst into laughter; "For all I know!", he said, raising his shoulders.

Still laughing a little, Valerion turned towards the bookshelf again and resumed his search. Adrien watched him for a while, smiling, but saying nothing. "By the way", he finally said, "you're looking really good today!".

Valerion replied with a smile that soon grew into a grin, and then into a chuckle. "Because I have legs?".

Adrien giggled, one finger curled against his mouth. "Yeah, legs suit you!".

Valerion laughed. "Oh, you...", he said, slowly shaking his head; then he smiled. "But thank you", he added with a courteous tilt of his head. He set a book into his grey sack: "That should be the last one", he commented. "I already put in the food, so we should be ready to go".
