GIRL HOLD ON–YOU ONTO SOMETHING
The first theory is INSANEEE im mindblown fr
As for the second, i just realised i might've been the only one to think of it this way so i may be wrong, but i always thought nunu and rocky were one and the same.
We know that in nunu's timeline or rather 1st mehemis's timeline, he turned into a tyrant in the end and was casted into a living statue by his people.
If we recall the origin of nunu we see that he mentioned after he was turned into the statue/later on died AS the statue, his soul could't let go of the destruction that befalled the nation of ebiz and that was how his soul came across the fragment of real anubis' shattered power while wandering between life and death, thus manifesting the powers of a god and turning into one.
And so i always thought that maybe the manifestation turned the heart of the 1st mehemis into the red gemstone (called as the bloody sapphire or smth similar in one of the episodes) along with his stone body, which would stand for centuries until meeting Li in the future while turning his soul into the god we know as nunu
I like to think that this somehow shows the connection btw the way rocky shattered and died and nunu's power of petrifying people and turning them into stone ash. Also how nunu is now living within or can connect to them through the lotus rocky gave li.
But despite my wishful thinking, this still doesnt explain how rocky recognised li in the future if nunu had no idea of who he was

While reading this chapter...something feels off. Mimi feels off...Last time that smile and how he behaved reminded me so much of Stone...but in todays chapter... He doesn't feel like either Mimi or Stone....this innocent, protective feeling that Mimi usually gives is not there?
...
So my brain remembered something. Mimi was soaked in Nunu's blood. I repeat: “Whether it's sacrificing one of my hands, or just making noise in my head! Mekhemes! Summon! (Shining light) -.-...I mean I already guessed that they will become one someday....but...are they already mixed? Mimi feels so strange...Also, when his future self could become a god...soaked in blood of a god...<<why not him too..?>> (Fact, Nunu could only see the future because of Ah Li showing him...but he has all of his memories from last life...) => Like really... Mimi feels so different
Regarding the crack in the chest...either the heart is already turning into a stone or the heart has already disappeared. I looked at the last chapter again; his reaction was really too much. Him looking scared when Ah Li tried to touch his breast...and then showed him the cracks on his stomach to kinda get out of the situation.
And today's chapter...when Ah Li hugged him from behind...-.- I think Mimi...or Mimi/Nunu kinda know that they are going to die soon...
Another thought...Its crazy but...could it be that the heart is Ah Lis? His blood awakened the heart stone...and therefore Stone. There is one thing we all already kinda recognised. We got Nunus timeline, and now we have Mimis timeline. There is a third one, and thats Stone's timeline. There are too many small hints at the beginning of the story. Stone's timeline already happened! Ah Li sacrificing his heart...because Mimi's heart turned to stone or kinda disappeared because of the cracks and Anubis/Nunus blood. Ah Li always chooses Mimi...even if it means sacrificing his life for Mimi...
Stone awakened through Ah Lis blood...Nunu was also turned into a statue but died and became a good...something is not right...why the change when they are both the same person? Nunu never met another Anubis, right?
