Nyx's hand lingers at his neck, petting through his hair and, admittedly, hovering worriedly. He's not used to being scared about something and not having anything he can actually do about it. Nyx is a very physical person, he tackles things in a very hands on way. Just fussing over Noctis (which he's going to do for days now) really doesn't make him feel like he's fixing anything.

"Yeah that's... incredibly dangerous, holy fuck. And whoever you were with just fucking dumped you there." There's a hint of that angry growl in his tone, the irresponsibility of the whole thing is infuriating. It can take hours, days even, for strangulation injuries to fully develop. If Carbuncle hadn't messaged him Noctis could easily have had a belated collapse and just........ stopped breathing.

The thought alone has him pulling Noct close once more, pressing another kiss to his hair. His free hand comes up to tap on the pendant he wears, words muffled and still angry but... clearly the kind of anger that comes from the depth of caring. "You, little shit, shoulda called me the second someone put something around his neck."
