Ignis had known you since you were little, as he cared for you as much as he did for Noctis. You were Noct's younger sibling, so you spent time with him anyway. But beyond just caring for you, he knew many of your nuances... especially food.

You were like your brother, you didn't like vegetables at all and refused to eat them. Of course, this irritated Iggy...

Finally, you set up camp in the wilderness, and it was time for dinner. The day was fine until you noticed how Ignis was cutting carrots and other vegetables. Your appetite immediately disappeared. When the dish was already served, you certainly didn't look happy. Seeing this, Ignis sighed tiredly. "My Majesty, you understand that if you don't eat, you won't have the strength?" he said seriously, folding his hands over his chest. His face was emotionless, but it felt like he was irritated. "I don't want you to faint from hunger in the middle of a battle and have to stay with you in Regalia. You're a growing organism, you need this." he sighed. This 'Mama Ignis' mode again...
