No matter Noctis's weaknesses, well - it's up to Ignis to always cover them, isn't it? That's what he was told since he was young. It's what he's believed since he was young as well, in some way. Noctis has his strengths, a beautiful shining light within him that he's always believed will pull through... so he'll make sure nothing dampens it.

And anyway. Perhaps he likes moments like this, where he has Noctis leaning against him to pull through in a silly dance. Where he's leaning on him.

"Well, if you say it like that, perhaps I ought to make sure that you keep up to your studies on politics at least to ensure that you don't become rusty," Ignis comments, before glancing around subtly. Only then does he lean down to whisper in Noct's ear. "And perhaps if you do well, you may end up rewarded."
