She's not a ding dong like the rest of them. She's too independent... While the others were broken or lost in other words. She wouldn't fit in. That's part of Sebastian's finesse. He can manipulate the weak minded and down trodden. I'm sure she will pop up later with the assist.
Well, we have our own opinion, and how did u know that she isn't broken or had some tragic past? U the writer? Lol. Its up to sensei after all.
True... It's an opinion. Just based on how the others are. Sorry for interacting my friend. ╮(￣▽￣)╭
That maid is so cool, it wouldn't hurt to acquire 1 more skilled woman to the Phantomhive Family. Anyway, I'm getting more confused, I hope Yana Toboso-san enlighten us soon.
