Road said that Cross Marian is sleeping, so Cross has somehow a connection to the dream realm?
And he can also built golems, itβs probably an ancient art from the previous world
The Earls suit is also like a golem, probably made by Adam. So the Campbells have definitely a connection to the first Adam and the first Road who could be in fact Lilith
no wonder that she fell in love with Nea, whoβs technically Adam
I still believe that Cross Marian is in fact dead, but because Road planned(yes, planned) to take his dead body after Aporcyph's actions, he is "alive" in her dream world. How can be alive in her dream world? Because only there time for Cross Marian could be stopped.
Why do I believe in this? The whole idea of taking Cross body means that she, from the very beginning, was watching for him, and she predicted that Apocryph's actions. Was that something that Cross wasn't able to predict? Or was this, in fact, part of Cross plan? I don't think that Cross planned to die there. Also, only because of those actions, many things changed, and Cross plan was altered in many ways, which is why you can say that now we will be able to learn the reason why Road wanted Allen to come to the mansion.
Now speaking about Road as Lilith. I think she is the Heart of Dark Matter, same as Lenalee is the Heart of Innocence, and she has to be resurrected in the future in her true form. Lenalee could be the new Eve. Now this explains why Noah didn't try to kill Lenalee and stopped their searching of the Heart. I believe Heart can be destroyed only when it is revived in true form. Which is why killing someone who has "heart" will not kill the heart.
As for Road/Lilith, because she is Heart of Dark Matter, I think her Noah's actions can be explained by a simple thing: she was betrayed by Earl. As for Noah, I believe she really represents Love of Noah. Which is the reason why she has to stay near Earl - not from her choice, but because of Noah's memory.
Now we know that Earl split into two parts after meeting Eve, which is a crucial point of everything. Eve was probably the vessel of Heart that Leenalee is right now. Also, I believe that Earl fell in love with her, despite Noah's memories, and killed first Lilith. Basically, this was the reason why everything happened in the way it did. So from Lilith's standpoint, she was betrayed by Earl, which is why she turned into a child, to not let her be a Lilith/Love, but stay as a Dream - she basically changed her mind into a child, which made her free to some point. She hates Earl but loves him because of Noah's memory code.
Speaking about the past-Allen. I think he met Road, and that was the time when the whole plan was created. Road chose him as her New Earl, who is free from Noah's memories. This is why I believe Road didn't help Neah. She loves Neah, because he is Earl, but in the same time she hates Earl. Which is why turning Allen for her into Earl is nothing but a representation of her free will. Because now she will be able to love the man that she loves, not Noah's memories. Which again explains every one of her interactions with Allen from the beginning, including the fact that she looks more adult right now than she was in the beginning (she changed just for him) Also, this explains why she let Cross just die. She wanted to use Cross to make Allen listen to her and remember his previous life, including his own reason for becoming Earl. I don't think that Past-Allen loved Roal/Lilith, but rather used her.
Anyway, this theory can be confirmed as true or false in the Mansion. Because this is really the crucial moment when we will learn who is who.
