"Hermione it's not that!" The emotionality confirmed Lily's suspicions and she moved to get up. "I'd just really rather we discuss these things away from fart-based humor, wouldn't you?" She tilted her head towards where Potter and his friends were sat, bantering among themselves and snickering before looking back to her friend, trying to hide her concern. Hopefully Hermione wouldn't be too upset by being led up to the hospital wing.
