I have Quincy who is a fourth year Slytherin that I’m bringing back…

He loves potions, and will happily dissect any animals that have parts that are needed for potions so that is always fun thread fodder. He might need help focusing on potions after that as he's better on focusing on things he can physically manipulate more than stirring.

A potential for backstory if you want is her helping Quincy with his studies either due to friendship or charity (as he’s middle class, muggleborn) as Quincy isn’t naturally intelligent (and definitely had help). His ambition and hard work are the only reason he’s now getting decent grades but it was hard work getting there - and will continue to be staying there.
