He's more than a little help--he's a lifeline. Ignis had learned to appreciate him before once they spent a good amount of time together, but now he appreciates Prompto on a completely different level. The others aren't capable of what Prompto is doing for him: keeping just enough hope alive in himself that he remains alive.

Something he'll never let Prompto, or any of the others, know. He had contemplated it in the first few days when he felt utterly helpless. Except Prompto had been there, always willing to lend a hand without a complaint.

Prompto's voice reminded him of why he needed to live. He could follow the devastation him dying would leave in Prompto's voice, and by extension, Noctis's. He couldn't do that to either of them.

Now, though, he's accepted it enough to push forward. It's not enough to look forward to the future, not yet. But it's enough to get him up every day.

"Especially the fresh air from an ocean breeze," Ignis agrees, and there's almost a ghost of a smile on his face as he 'glances' back.

He can at least still hear and smell the wind. Almost taste it sometimes, too. Feel the sun on his face. That, too, is a lifeline.
