[The insult is nothing new to Nico. In all honesty, he's heard and endured far worse than being called a smart ass. Really, it's almost cute.

Actually, the only thing Jason says that gets a reaction out of Nico is when he flings the word "boyfriend." He flinches from it like he expects to be hit after it's said. There's no way the man could possibly know about Nico's...situation, but the reaction is still automatic.

At any rate, it'll take more than that for Nico to doubt Hiro. Once earned, his trust is hard to break. Even after all Percy's done in Nico's life, he still trusts the son of Poseidon. So...something like this in comparison? It's almost negligible, maybe even laughable. Besides, he's more concerned about Hiro. He looks at his friend from across the table and shakes his head.]

I would've left the moment you two started talking, but I doubted it would've helped matters any. [He sighs, soft and quiet.] I still trust you, Hiro. You haven't done anything to make me question your motives or break my trust.

[The 'so far' is implied. It truly doesn't need to be said.]
