Jack kept consuming the confection until he realized his bowl was empty and his spoon's lack of anything delicious. How saddening, good thing it was easily replaceable. despite the fact there were multiple sundays and he didn't have to if he intended to continue eating, Jack quickly attempted to snatch Nikaido's bowl and playfully stuck his tongue out at her.
