Why is everyone talking about twins? Isn't it only one person

Haha! I haven't thought of that! But I did notice in the cover he was shorter then the Mc. But in the comic, I was a little upset that he was taller. Now, I'm hopeful! I've also noticed the hair split is different for each encounters so it is a possibility. Maybe the twin took over Cilve when they first meet as kids and that same twin showed up with a hood!
