Episode Title:
Sparkle's Seven.
Episode Description:
Shining Armor summons Twilight to Canterlot to settle their foalhood "Sibling Supreme" sibling rivalry competition once and for all. Having implemented a new set of security measures around Canterlot Castle, he challenges Twilight to breach them and steal a toy crown from the throne room. Twilight devises a plan with her friends, only for Shining Armor to boast via letter that he has already guessed it, prompting Rarity to suggest that each member of the Mane Six do the opposite of what he expects. After their plans all fail, Spike urges Twilight to go ahead with her original strategy; they successfully reach the throne room, only to be intercepted by Shining Armor and Princesses Celestia and Luna. As Shining Armor gloats over his victory, though, Spike suddenly reveals that he has the crown – passed to him by Luna, who had secretly agreed to help him following a disagreement with Celestia about improving castle security. Twilight and Shining Armor award the crown to Spike and acknowledge him as their little brother.
