I feel like modern day Sebastian would be so into his butler aesthetic that he'd be a crunchy mom. No artificial flavors, preservatives, etc. And no plastic bottles.
ABSOLUTELY NO MICROPLASTICS
(At first...)
And then Ciel does that ONE thing to piss him off enough to throw his Butler's Aesthetic out the window and want the child to die faster.
Such as:
The tide has TURNED
All of the sudden, Little Master gets some new seasoning to his organic dishes.
And Sebastian would be serving it to him like
"Ah, one must have faith that this method will prove effective. He will die young, surely"
