Justin and Ernie
"In a way, Seamus is like Zacharias - they speak their mind, and often forget to put a filter on their mouths." He grinned. "Just like me at times. No wonder I like them, even if Zach might not like the fact that I like him."
Justin took out his wand and used it to uncork one of the 'music' bottles, and grabbed the nearest empty glass to fill. "You know me better than that, Ern. Nothing malicious here. Life is too short to spend it feeling put out at being pranked on." He passed the glass to Ernie. "Here, try it. Let me know if the music matches your mood, just in case it was specific to me, or just coincidence."
