Forum:Ending

Hey, so i just finished watching this a second time. Last time i watched it was when i was 10 or so. Anyway in the end, why did Simon have eyes like Kitan did right before he died along with the spiral kings eyes. What does this signify if anything. Also what i teh difference between SUPER tenga toppa Gurren lagann and regular Tenga toppa Gurren Lagann?
