So I was thinking about this and its possible repercussions in the current arc, i.e what Lizzie may still do before the arc ends. 

I know this might not please everyone, since she’s often targeted by criticism, but she’s still a huge part of the arc (and of our!Ciel’s life) and Sensei dedicated an entire chapter recently to how she’s feeling, so you can bet it’s going to matter. 😀

Anyway, when you look at Lizzie in ch58, what she’s describing regarding the twins are two opposite dynamics: 

• when it comes to real!Ciel, she expresses passivity => she’s the one being protected
• and when it comes to our!Ciel, she expresses activity => she’s the one who protects

Granted that this shouldn’t be taken too literally because she indirectly protected real!Ciel by fighting against Seb in ch117, just like our!Ciel protected her in ch14 for example, but this may still be interesting to consider the next developments. 

After all, even though she did fight against Seb to stop him from investigating the labs, otherwise she’s been rather powerless when it comes to real!Ciel’s situation…

…or to what he (and UT) did in the current arc, which fits the passive dynamic.

Similarly, where real!Ciel telling her that he found strong women scary (when they were kids) is what led her to think she should be protected by him, the Campania arc happening 3 years after she decided that she would protect our!Ciel gave her the opportunity to reveal her true self to him…

…which is something that he accepted and he didn’t think any less of her after that (even when she almost kicked him in the face in ch107 xD). 

So back to the current arc, where is this difference of dynamics supposed to lead Lizzie? Especially now that she’s freed from real!Ciel and the blue sect (who most likely didn’t give her a single chance to figure out why our!Ciel would even lie in the first place)? 

Most importantly, if the current arc so far had Lizzie being passive because she was by real!Ciel’s side, now that she’s left him, can we expect that she takes on a more active role, especially considering how she’s not even pissed at our!Ciel but just super confused and blaming herself?

In any case, I think a little detour by home is a great thing because her family always supported her and also taught her how to be strong.
And, I don’t know if Frances’ current absence so far is supposed to play a role in helping Lizzie realize on which side she wants to be, but it might (especially if Frances already knows about our!Ciel lying and since Sensei said that Lizzie took her mom as a role model).

My personal opinion is that if Lizzie eventually decides that her place is by our!Ciel’s side (which I think is likely to happen for many reasons), then I bet you that she’ll most likely become very active again in striving to protect him, even from her original fiancé (aka taking up the sword again and fight like a badass). 

EDIT: forgot to mention but there is still that random info that Sieglinde now understands how blood transfusions work + that Wolfram has got the same blood type as Liz => could be a hint that she might get hurt because she’s going to choose our!Ciel.
