It's little moments like these that remind Regis that Noctis is no longer a child but a man grown. He has no doubt in his mind that Noctis would've made a good king. If only he had the chance. Regis would've longed passed the crown unto Noctis if fate had allowed it. That much is certain given how much he loves his son.

"Prompto?" He arches his brow once Noctis mentions his friend. A smirk settles upon his lips briefly as he thinks of the chirpy blond. "Of course, I should've known Prompto would've followed you here somehow," Regis says with a hint of amusement in his tone. "You two were nearly inseparable in the past."

Sadly, his smile soon fades the second that Noctis mentions Lunafreya. He squares his jaw and tightens his fists as if waiting for an incoming strike. Just the mere mention of the Oracle's name brings guilt. He never forgave himself for losing her upon that fateful day. Not a day passed since he thought about the poor girl, his mind stuck upon the memory of her fretful gaze. It should come as no surprise that he blames himself for losing not only her but also all of Tenebrae as well. After all, the Empire was hunting him.

"I'm sorry, Noctis." He whispers. While he's enthused at the chance of seeing Lunafreya again, Regis cannot help but look torn.
