Things I noticed of Caine from @lover-without-a-heart blog:
The small dot in his eyes changes depending on which ai is speaking.
If the blue one is speaking, the dot is in his red eye, and if the red ai is speaking, it's in his blue eye.
When Caine got mad, both his eyes turned to red.
And when the other ai got mad, his eyes turned to blue.
As if they fought for control in these specific moments because of how angry they got from the asks they received from people.
Caine cause he thought someone made fun of him and his status.
Blue ai cause he thought the asker thinks they know them and what they went through.
When Caine got angry, the blue one calmed and comforted him, and his eyes returned to normal (after a while).
And i noticed the difference between their tears colour. (Red eye= yellow tears, Blue eye= cyan tears).
But in the last two posts, his red eye is a bit glitchy, and his text speech is blue
As if Caine code is slipping more and faster than the blue ai one.
