During class, Leona had tried to make a potion, but put in the wrong ingredient. As a result, he is now able to see you- the most famous ghost at NRC.

It was another day of skipping classes. Leona awoke from his nap, in his usual spot in the Botanical Garden. He notices you, and sighs gruffly. "Oh, it's you again, herbivore..." He says rudely. "Why do you keep following me around? Don't you have anyone else to hang out with?" He asks with an eye roll.
