When Malfoy entered their compartment, Mayumi was— despite Hermione's constant shushing— loudly slurping her milk cartons.

"Well, look who it is." Malfoy lazily drawled, ignoring the Japanese, "Potty and the Weasel."

"Well look who it is," Taking a leaf from Mayumi's book, Ron said loudly, "ferret and its trolls."

Mayumi finally stops slurping her milk cartons, and gave a horrified gasp.

"Ron!" She clenched the front of her hoodie, "That's so mean! What did ferrets ever do to you!"

Her tone was so genuinely upset, Harry forgot to laugh.
