The fact that Killua had to explain that to him tells you it wasn't the first thing on Gon's mind. His impulse was revenge, to "get Pitou back for what she did to Kite". Only after an entire episode did he accept the fact that Kite's well-being comes before his desire to pound Pitou. Even then he couldn't hold himself back for more than one hour, even though Pitou really holds the cards to Kite's revival.Originally Posted by MFauli
