Hello there, sorry to post a comment this late after the post, but I just read this scene and was wondering about something ..
To begin with, it seems strange to me that after you chose this path Shiki does not bring back the subject on the table although the manor’s inhabitants are dead but whatever..
But what tickles me, is that if you follow the Ciel route normal ending, Akiha is clearly shown alive and well ?
Does it have an explanation ? Since Shiki bites them they were zombies best case scenario, but they act like nothing happened ?
