Well, Nevin's kindness certainly knew no bounds.
First, he offered a nice cup of tea, the flowery scent reaching Ezra's nose before he had even set the cup down. Second, the alchemist had intentionally picked a slower day as to not have the Homunculi get overwhelmed by the villagers who might have questions outside Ezra's expertise. It was the perfect training day, so to speak. They hoped that the day would go smoothly, for both their sakes.
The discussion for the personal project perked the Homunculi up immediately, and their attention went full focus. Apparently, the alchemist had made some headway, despite how busy he could have been. The man had found out another school of magic that helped bind the Homunculi's body together, but before he could mention what it was, Ezra had asked about his eating habits. The man hesitated at the questioning, which, to be fair, might have thrown him off his train of thought, but he slowly drank his tea before answering. Something didn't feel quite right about that.
...'Consumed an adequate amount of nutrients for the day?' Why did he speak like that? It was much too formal for their usual social interactions. His gaze shifted to the door, and Ezra's brow furrowed. Between the wording and the refusal of eye contact, the similarities between Nevin's answers and the little child who had wandered in here and tried to trick the alchemist for more candy were too identical.
"Oh, is that so, Sir Nevin? What did you have for breakfast? Because if I find out you are attempting to lie to me, I will have no choice but to tie you up and teach you a lesson-" They paused as the door opened, and a gruff, older looking man stumbled in. It was clear by his clothing and build that he was one of the local miners, and Ezra gave a gentle curtsy and smile to the man.
"Greetings, sir, and welcome to Herbal Magick! Please do not hesitate to ask us any questions!" As soon as the man turned his back to look at one of the shelves, Ezra whipped their head around towards Nevin and stared at him intently, keeping their gaze locked. "We shall discuss this later."
