[After Gamora reveals Thanos where the Soul Stone is, they travel to Vormir, the Stone's location]
Welcome, Thanos, son of A'Lars. Gamora, daughter of Thanos.
You know us?
It is my curse to know all who journey here.
Where is the Soul Stone?
You should know: It extracts a terrible price.
I am prepared.
We all think that at first. [His face is revealed as the Red Skull] We are all wrong.
How is it you know this place so well?
A lifetime ago, I, too, sought the stones. I even held one in my hand. But it cast me out, banished me here. Guiding others to a treasure I cannot possess.
[Red Skull leads Thanos and Gamora to a shrine on the edge of a tall cliff]
What you seek lies in front of you. As does what you fear.
What's this?
The price. Soul holds a special place among the Infinity Stones. You might say it has a certain wisdom.
Tell me what it needs.
To ensure whoever possesses it understands its power, the stone demands a sacrifice.
Of what?
In order to take the stone, you must lose that which you love. A soul, for a soul.
[laughs]
All my life I dreamed of a day, a moment, when you got what you deserved. And I was always so disappointed. But now, you kill, and torture and you call it mercy. The universe has judged you. You asked it for a prize and it told you no. You failed. And do you wanna know why? Because you love nothing. No one.
Really? Tears?
They are not for him.
[Gamora looks at the Red Skull, and as her bitter smile fades, realizes what is about to happen]
No. This isn't love.
I ignored my destiny once. I cannot do that again. Even for you.
[Gamora takes the double-edged knife Thanos had given her, then tries to stab herself in the stomach. But Thanos uses the Reality Stone, turning the knife into bubbles] [anguished]
I'm sorry, little one.
