Could've seen the past life too. Moon eye gives future foresight and the first vision he saw was of future but 2nd one wasnt revealed to us but we are given bunch of suggestive hints like the piercing light wadjet panels and thoth attempting to force wadjet capabilities n the way whatever it was, even a glance was too powerful n overwhelming for him. Korean readers noted not only did he stop calling seth uncle he dropped his formal speech too. He didnt cry when he saw seth dissappear in 1st vision. On contrary he was moved that seth would do smth like that for him. But the second vision was shocking enough to make him cry n become agitated. Might be presumptious but I dare say HTE sneak tease maybe?
Hours said "I have to get to Seth" not "I have to get to Uncle Seth"...
Did he see the future as him living it, or did he perhaps trigger something that made Horus drop the Uncle title...?
