Killuas eyes just lighting up when he sees what he believes to be Gon. He hadn't sensed Gon's aura, but he desperately wants to believe that his friend is back.
Killua grabs Allukas hand and runs up towards Gon, who seemingly hasn't noticed them yet. They're just a few feet away, and Killua is getting ready to jump at his friend and give him a hug. He stops in his tracks when Gon turns to look at them.
Everything looked right. Gon's eyes seemingly had their same bright shine that they always had, but Killua couldn't feel any of the familiar warm light coming from behind them. All he could feel coming from those eyes was a hungry darkness that was using his friend's face to lure them in. Killua kept his hold on Alluka's hand as he pulled his sister behind him. "...Gon?" He asked, hoping against every instinct he had that it was really his friend.
Gon's face changed then, to an expression that Killua recognized immediately. His grip on his sister's hand got tighter as he turned and started sprinting away from the person at full speed.
Killua didn't look back. If he had, he would have seen his friend's face and body distorting and stretching into another familiar face. The spiked hair that he loved turned blacker and longer before falling and resting along his brother's back. "I thought seeing his friend's face would make him more inclined to hear me out this time..." Illumi sighs as he takes off after his siblings. "Maybe next time, ill use the real thing."
