The name's Killua, he and I talked quite a bit about stuff. I never got to meet him face to face though. [Some of which was highly classified.]

Mechanic, your the one that fixes his arm then. [First impression are funny thing they don't tell you everything about a person. Most assume Kil a spoiled brat, which he is, they just don't realize how dangerous he can be.]

No danger here, he's just be overly dramatic.
