Lee's Hidden Strength: Forbidden Secret Jutsu!

Synopsis
Lee's target was actually only a decoy — a hollow clone made of sand. Gaara reappears and fights Lee, who is now weak from using his Front Lotus again. Lee quickly recovers this time, demonstrating his ability to open the Second Gate. He then powers himself up by opening the Third Gate, frightening even Gaara. Guy and Neji have flashbacks to before Lee became a genin and right after he became one, showing his determination to be a respectable ninja through only the use of taijutsu.
