How would she know? After what the twins went through, it's reasonable to believe "Ciel" would go through a change and become gloomy like the fakeciel. I think it's mostly the fact that she was lied to and she's been loving the wrong person the whole time, thinking it was correct. It's not just a matter of engagement.

Should i explain this? I know she feels betrayed ,but can she thinking clear about fakeciel feels and how fakeciel always saved her all the time? Can she ask first about why fakeciel do it and what happened after the accident , and not make a conclusion like that fakeiel is liar? U must consider fakeciel too that he really love realciel. Fakeciel become realciel for make a revenge to who killed realciel. And u must know how fakeciel feels when knowing that his twin brothe who had deadac, comeback alive

How can you expect her to be thinking clear at a moment like that? She's hurt, she can't exactly think of the most logical explanation as to why fakeciel would lie to her. We know the full story but she doesn't so it makes sense for her to be so upset. She doesn't know that fakeciel pretended to be the real Ciel, only we know that because we were given that information. It's a crazy story involving grim reapers and demons, things that she doesn't know anything about. In the spur of the moment, you can't expect her to be completely understanding and reasonable.

It's not as simple as being betrayed, she's probably going through a shit ton of mental baggage. You can't expect her to be super reasonable and understanding in the situation right now. And it's not like the others weren't going to find out that the fakeciel was the one lying anyway, given that the real ciel was right there.

Well if ciel had told her what do you think she would do? Ciel is playing detective and is seeking revenge, he doesn't have time for people to be getting in the way. He couldn't exactly just come back and be like hey everyone died but I the younger and weaker brother will now be the master of the phantomhives. 1. No one would accept it 2. Hed be looked down upon since everyone knows how weak he is. I get what your saying but it's just not logical for ciel to tell lizzy everything that went down. Its for her own protection too.

The thing is, she doesn't know any of that. All she knows of the story is that the fakeciel lied to her and everyone in general, claiming to be the real ciel while letting Elizabeth go on thinking she's his real fiancée. In this situation, all that's clear to her is that the fakeciel lied to her and that the real ciel is alive. She doesn't know the indepth parts of the story like we do about the fake ciel's motives. She doesn't know it was for her protection. She has every right to be pissed
I used to hate Elizabeth cause I found her annoying but I fucking love her now. I feel so bad for her, imagine how betrayed she feels, loving the wrong person this whole time. It's okay to not like her but her emotions are reasonable and most of the backlash against her is cause she puts fakeciel at jeopardy but...can you blame her?
