Considering Inigo has seen the way Taiki has scolded Tidus for his sake before, he knows what Tidus is trying to do here. He can smell it in the air! He's trying to turn this table around on him, and Inigo's jaw already drops, ready to defend himself..

.. but then there's no scolding from Taiki.

He momentarily puts down his jar to wrap his arms around Taiki in a hug.

"Taikiii, why do you always have to be so sweet, huh? You really are too good for this world!" Even letting a scoundrel like Tidus have his share of the food!
