Prompto withers a little at the sigh. He knows that for the most part it's just Iggy being Iggy, but he doesn't want to make his friend feel even more put upon than he already is. He wants Iggy to feel more independent and confident again, and he still has high hopes that at least one eye will heal back to normal again. He's not willing to give up on that yet.

At the same time, Prompto likes feeling needed and useful. He's not a noble so he has no idea how to handle the political aspects of everything thats going on. He's gotten decent with a gun, but nothing he's been training for is of any use at the moment. So he dotes on Ignis while Noct recovers and Gladio runs interference with government officials and whatever else needs doing in that regard.

He feels so helpless. At least helping Iggy gives him a purpose.

"Right! I'll get your clothes ready!" He says with as much cheer as he can muster, finally heading off to the wardrobe.
