I am sure you are aware but there are all kinds of different fires, you can see numerous sorts in a kitchen. Grease, coal, fire, oil. They all have the same basic properties and needs, yet the nature of the fuel being used changes the way you have to fight the fire. I am trying to see if I can resolve a way of putting out any kind of fire safely and instantly within a home."

He nods and then something catches his attention. "Oh, is that dinner? It looks good." He takes the plate from her and without sitting down he digs in with the fork she'd brought. His attention returning to the chalkboard as he begins to eat. His brother watching with wide eyes from the doorway.
