Christian's behavior on S4

I apologize if this has been discussed before!

Rewatching all seasons and am almost to the end of season 4. As a huge fan of Christian Siriano's clothes, I'm shocked at what an unmitigated asshole he was on this, his first season with PR. Been so long since I watched it, I wasn't remembering his behavior. Arrogant, pissy about others' clothes, ignoring Ricky as beneath him, grumbling about each of the challenges, and more...

He's obviously immensely talented, but ugh. I hope he's matured since then!
