Sméagol:
Give us that, Déagol, my love.

Déagol:
Why?

Sméagol:
Because it's my birthday...and I wants it.

[Déagol refuses, and the two get into a fight that ends with Sméagol strangling him to death. Sméagol then takes the Ring]

Sméagol:
My... Precious...

[Sméagol puts the Ring in his finger, causing him to be transported into the Shadow World; the scene changes to the Misty Mountains where Sméagol is mutating into Gollum]

Gollum:
[voice over] They cursed us. 'Murderer', they called us. They cursed us, and drove us away!

Sméagol:
[coughs] Gollum! Gollum! Gollum!

Gollum:
[voice over] And we wept, precious. We wept to be so alone. And we forgot the taste of bread, the sound of trees, the softness of the wind. We even forgot our own name. My precious.
