A while earlier…
Unwilling, Bloody Mary was bringing Gluttony down the ocean and into the chaotic darkness.
It wasn't unwilling to bring Gluttony into the darkness, it was just that going into the place required Bloody Mary to be in its illusory form and it still had to 'cover' Gluttony in the process, so it was quite a burden for the High Demon.
Fortunately, Gluttony had a similar illusory form, thus easing Bloody Mary's burden. Had Gluttony stayed in his solid form, no matter how hard Bloody Mary tried, it wouldn't be able to bring Gluttony down there.
The thing that irritated Bloody Mary the most was when Gluttony was inside Bloody Mary, the hungry sin wanted to taste the High Demon with its tongue.
Bloody bastard!
You really eat everything you see!
Wanna have a rock? What about pesticides? Damn it!
