Pretty close actually... what he mostly got out of Acedia's memory was 'wow this is the only guy who takes fighting seriously in this entire universe'. And since Hibari FOUGHT UNTIL HE COULDN'T MOVE Dawn did gather that he takes it VERY seriously... And since Hibari has been tolerant toward him he hasn't actually seen much of Hibari's totally insane irrationality.

Hibari is more... petulant... than he expected. It's definitely cute. And he's heard enugh about him from Dino to have the vague idea that this kid is a little crazy, but nothing really sticks out of him as a point of worry or contention so he's just like derp derp this is a cool guy to hang out with.

Are Dawn and Yuri ever really going to have a sleep over and talk about crazy boyfriends.
