S07E182: Silent Storm

Gokudera, impatient with the trials, begins training at the park early in the morning. While Gokudera is busy looking for Uri who runs away, G disguises himself as Gokudera with Fong buy some times for him. At school, Tsuna and his friends notice that Gokudera has been calmer and more reliable than usual, which arouses Tsuna's suspicion. While walking home, Tsuna and Gokudera run into the real Gokudera who reveals that G has been impersonating him. G reveals himself and asks Tsuna how his performance was at school. Tsuna comments that G has been reliable and helpful, which causes G to denounce Gokudera as being unsuitable to be Tsuna's Right Hand man and deems him unworthy of being the Storm Guardian. When G demands Gokudera to return the Vongola Ring and leave Japan, Tsuna defends Gokudera stating that Gokudera is not supposed to be his Right-Hand man but his friend. G then reveals that his trial was to test Tsuna and Gokudera's bond and deems him worthy of the Guardian of Storm.
