There's a line between a narcissist and an arrogant asshole, 'kay? No offense to anyone, but why does everyone think Solar likes to selfie every second of the day. If he is, it's at the most inappropriate time ever.

Everyone: *dying* 

World: *set on fire*

Solar: Oh, just a second. I need to upload this selfie to Instagram. I spent five hours trying to get the lighting just right. Oh, sorry, that fire was me so I can get the background just right.

THERE AIN'T GONNA BE INSTAGRAM IF THE WORLD IS DESTROYED SOLAR

The light element is achieved through a high intellectual level. Light/Cahaya may be an arrogant prick, but despite Solar's brief appearance, he acts wiser as he no longer looks down on Vargoba.

Just because he's light it does not equalize as an attention seeker. He's the smartass, the nerd. Not the popular kid who selfies absolutely everywhere.
