Hisoka entered the large tunnel, grabbing the badge 44 as he walked past, that meant that there was 43 other people in the room before him, one of them being you. You were the first person to enter the room meaning you had the badge labelled as 1. As the man continued to walk through he spotted you, though he did not approach you, instead making his way to a less populated area of the tunnel. Similar to how you did.

You were perched on one of the rusted pipes around thirty feet high which gave you a way to watch everyone at once. You looked really composed all the way up there, he doubted half the people had even noticed you up there yet.

He was shuffling his cards observing the rest, occasionally looking up at you to see if your gaze had drifted to him. Hisoka's weapon of choice is a set of ordinary playing cards, which he uses in combat to lethal effects by wielding or throwing them in conjunction with his Shu.
