Which eye is bigger? The green one or the blue? In some instances, it's his blue eye, and in other's it's his green. Sometimes, both eyes are the same size. Soooo what does it mean? Well, it probably has something to do with what he is feeling. When both eyes are the same, he is feeling calm and regulated. In the parts where his eyes are the same are in ep. 9 where he is questioning his choices, and letting the blue AI go. I'm not sure about the blue eye larger vs. green eye larger yet, but I'll look into it some more.
