In one panel he saw the kunai that was thrown. He and Sakura put on a stupid face and the translation was a big exclamation mark(!)
Sakura has no idea why a kunai of that shape appeared, her face gets more confused where Naruto smiles.
The kunai tips off Naruto so he can give a cool reaction like "hey everyone btw the 4th is my dad" instead of "OMG DADDY."
Some people would rather Naruto go hug daddy(those who were 'disappointed by Naruto not being suprised'). I appreciate him being nonchalant/ casual as he tells the world for the first time his true heritage.
