  Navarone: Taya, this is Twilight. You can blame Twilight for me being here.
  Taya: (whispering) Thank you.

• Nav's final goodbye to his sister, after getting sent back through time.
• Rainbow Dash's attempts to cheer Nav up after his Tomato in the Mirror moment.
• After finding common ground, Nav and Princess Cadance become good friends. He even considers her "Best Princess" because she truly has his best interests at heart and has never tried to use him.

• Nav helping Rarity make connections in Canterlot, as well as protecting her from trumped up treason charges.
