Deidara probably still doesn't get how outmatched he was, even after Itachi casually dismantled him with that genjutsu – I mean, wow. It made me realize just how much Itachi always holds back, and my gut reaction was a mix of awe for him and genuine pity for Deidara's shattered artistic pride. It just highlights how Itachi's strength isn't just power, it's about chilling mastery, which is kinda terrifying.
