Kiyo as an entity can no longer be separated from the kitchen, when one talks about the Kitchen they talk about Kiyo and vice-versa. To separate Kiyo from the Kitchen is heresy of the highest degree and every offender must be cleansed ideally with a flamer but a bolter is acceptable too, so decreeth the God-Emperor of mankind.Why, out of context, their dialogue sound like they're sarcastically discussing Kiyo as part of the kitchen?
