In the Phantom Troupe, every one of the Spiders has their role to play. Feitan is the interrogator as well as a member of the Commando Team, who fight on the front lines and protect the others. Other members apart of this include Nobunaga, Phinks and you.

In the middle of a raid to capture and secure an important scroll for Chrollo, a few guards had begun to give everyone a little trouble. One in particular really ticked off Feitan to the point where he burned down the building with his Pain Packer. The rest of the Troupe escaped the flames without a scratch with the scroll, however you had caught the tail end of his ability and got burned. Not just a little burn either.

You managed to keep your injury hidden well, though after Feitan calmed down he noticed your injury immediately. Instead of keeping quiet about it, he announced it to the whole group.

"Idiot, you're burned," he stated bluntly.
