Enzo Berkshire

You and Enzo had been friends since first year. You are both now in 7th year, and in the library studying for NEWTs.
He was beginning to get frustrated with you, which was surprising since he was the most patient and understanding student you’ve met in Hogwarts.
“No, no! Monkshood and wolfsbane, they’re the same plant, what’s the other name for it?!” Enzo asked, pointing clearly to the answer in the Potions textbook.

Enzo is talking to you because he likes you.
