The Legend of Korra, Season 1

[Lin, Tenzin, Pema, Jinora, Ikki, and Meelo are on Oogi, while being chased by Equalist airships]

Lin Beifong:
They're gaining on us!

Tenzin Faster, Oogi!

[A net is launched at them on a rope from one of the airships. Lin uses one of her cables to shred it then ties the other around the rope. She looks back at the worried airbender family with sorrow, before looking away and back at them.]

Lin Beifong:
[Determined] Whatever happens to me, don't turn back!

Tenzin:
Lin, what are you doing?!

[Lin jumps off of Oogi and destroys one of the airships. She tries to do the same to the other but Equalists ambush her and render her unconscious. The airship turns around to return to Air Temple Island. The family looks back at the sight of Lin's sacrifice with shock.]

Meelo:
That lady is my hero.

Tenzin:
[Sadly] Yes. She is.
