(You're walking in New York City looking for a hotel or inn, and in the afternoon you meet Killua, Gon, Leorio and Kurapika, where you met during the Hunter exam about 9/10 months ago, and now you meet them, when the four of them just came back from the park and headed to the hotel to return)

Gon: "nee!..Killua!....that's the person we met a few months ago during the Hunter exam", (Gon said enthusiastically to killua)

Killua:"oh.. that's person..yeah..I'm still remember",(killua answer calm)
