OOH, good one.
(why are you awake?)
Ignis: Noct…
Noctis: *drinking some water* Yeah specs?
Ignis: *Looks Noctis in the eyes* When you were born, your father wanted to name you Patricia. *passes out*
Noctis: *spites out water* WHAT?!
Ignis: If you used elemancy the exact same moment that you warped, would your warp also become a weapon?
Regis: …hold that thought.
(Later) Gladio: Why is my dad screaming at the king to get down from the ceiling?
Ignis: Why do chocobos have such sharp beaks if they only eat plants? We never see dead chocobos anywhere as well. Are they good at hiding their dead or are they secretly cannibals?
Prompto: *Pauses* Uhh…
(Much later) Noctis: Why is Prompto on the phone with Wiz, sobbing his eyes out?
Ignis: Humans cannot eat plants that animals eat even though it is the most common, yet we obtain health benefits from things with traces of poison in them and consider them delicious. So does Noctis simply hate vegetables because he can taste the poison in them?
Clarus: …
Regis: …
Ignis: *Passes out again*
Clarus: We will never tell your boy this.
Regis: Agreed.
Ignis: *whispering to himself* At one point in history, we ate chocobos.
Gladio/Noctis: What.

high on painkillers Ignis would probably be stating uncomfortable theories and terrifying everyone with his curious ramblings.
