"Hey! You know Duo? I don't envy you. That kid's a pain in the ass. And if by 'cloaking' you mean 'invisibility' then he was already at the bottom of the pyramid when he got here because I was here first." Ok, so his peeping jutsu wasn't true invisibility. It was more like ultimate non-noticeablity with a dash of chameleon-like camouflage, (which was why people caught him perving. You can't make noise and expect people to over-look the interesting lump.) but the kid didn't need to know that.
"Well let's go take a look then!" He said, managing to bump his head on something else. He hissed and scowled and rubbed his head in another spot while he maneuvered out of the kid's way.
