[ Illumi reflects that he's been tense through this whole exchange since he's entered the mansion and dining hall, so he should not be so surprised by her impression that he was suspicious of the food being poisoned. He had intently however watched her reaction to sampling both pieces of food, before finally picking up one of the apple bunnies with his chopsticks and bringing it to his own mouth. He takes a small bite after examining it and chews. Nothing had smelled or tasted off as he chewed then swallowed the apple. And even assuming the possibility a tasteless or odorless poison, unless it was something unknown or strong enough to kill a whale, he would be fine.

So while he had been worried of it being poisoned, he was more concerned with it effecting the woman eating it and not him. For himself, he was more considering the chance of some sort of other mysterious consequence. ]

You didn't think to ask what it was before eating it? ...Well, I'll tell you.

For the first one, it is grilled egg and rice. The second was sausage. They usually are shaped like an octopus when put inside this type of lunchbox.

[ He pauses to eat the rest of the apple bunny he has in his chopsticks then picks up one to give to her. It's his favourite part of the bentos his mother would make him and his tone when he speaks next is faintly tinted with a bit more emotion than his normal one. ]

This is an apple bunny.
