When something's wrong with Killua, Gon just knows. He has an instinct in his blood, like a twist in the air. It can be something minor, like when he came home with just a feeling, and there Killua was with his cute little puffed-out cheeks, sulking that there weren't any more Chocorobots. Gon had to remedy that, of course! Other times it was worse. Gon had the worst feeling in the pit of his stomach, so he left Ging on a day they would meet. He didn't care about rekindling anything with his dad, fuck it, Killua was his everything now. When he heard that broken wail, he broke down the bathroom door and scooped up his kitten into his arms. Gon's eyes widened when he heard, 'G-Gotoh's dead; h-he has been for a while...'

He just held Killua closer than he ever could to the broad expanse of his chest.

So when he knows something is wrong, he knows. It sits uncomfortably in his gut, and he runs, feet pounding on the ground.

When he sees Killua's small frame lying on the concrete, red obscures his vision. Anger emerges from his every move, and a dark aura surrounds him. These guys were chumps, and the one who's left freezes, and Gon's pretty sure he pees himself.

"W-wait!"

Gon doesn't wait, his knuckles hit the soft flesh of the guy's face, and he can feel his skull crack under the force.

He rushes over to his Killua, gently lifting him off the ground and glaring, teeth bared at the shadows around him, knowing that the asshole's friends are hiding.

"What did you do?!"

One by one, they run, and Gon pulls Killua's impossibly small frame close protectively.

"M-mmm..."

Killua stirs, and Gon gently and lovingly plays with Killua's bangs.

Those big blue eyes are dazed and confused, and Killua glances up.

Gon...

"G-Gon...?"

Gon... it's his Gon. The immense pain seems so far away, despite how it's running up and down his veins, and he reaches up, desperate but to weak to wrap his arms around Gon's neck.

Gon shushes him gently, picking him up carefully like a princess, and Killua clings to Gon, wrapping his arms around his neck.

"What happened, baby? Did they hurt you?"

Gon's soothing deep voice makes the severe shocks running through his body melt, and he shakes his head and whimpers.

"G-Gon... I don't know... m-my G-Godspeed..."

Gon... Gon... Gon... he presses his face to Gon's chest, tears soaking up in his deep green shirt.

It hurt so bad. He felt like he was being ripped apart. All he wanted was Gon, Gon to hold him, Gon to make it all better... he called for him.

And Gon never lets him down.

That's why he wasn't scared even when the darkness took him.

"Your Godspeed, what, baby?" He shushes Killua quietly, rubbing his shoulder and pressing a kiss to the crown of Killua's head.

Killua leans into Gon's touch, closing his eyes. He feels safe.

"I-It's like it exploded..."

He doesn't know how else to explain it. It short-circuited, and his vision went pure white, and he couldn't even move.

He can hear Gon inhale sharply, and Killua smiles weakly but softly.

"B-but it's okay... I wasn't worried... I knew my big dumb hero would come to save me..."
