Avengers: Infinity War2018

Thanos:
[speaking to Loki as he is shown surrendered by the Black Order] I know what it's like to lose. To feel so desperately that you're right, yet to fail nonetheless. [grabs Thor by the head] It's frightening, turns the legs to jelly. I ask you, to what end? Dread it. Run from it. Destiny arrives, all the same. And now, it's here. Or should I say... I AM.

[He soon shows the Power Stone in the Infinity Gauntlet]

Thor:
You talk too much.

Thanos:
The Tesseract... or your brother's head. I assume you have a preference?

Loki:
Oh, I do. Kill away!

[Thanos uses the Power Stone and tortures Thor, and Loki has second thoughts for a few seconds]

Loki:
ALL RIGHT, STOP!

[Thanos stops using the Power Stone]

Thor:
We don't have the Tesseract. It was destroyed on Asgard.

[Thanos ignores him and continues to stare at Loki. Loki pauses, before revealing the Tesseract in his possession.]

Thor:
You really are the worst, brother!

Loki:
[Stepping toward Thanos, holding the Tesseract in front of him.] I assure you, brother... The sun will shine on us again.

Thanos:
Your optimism is misplaced, Asgardian.

Loki:
[stops and pulls the Tesseract back] Well, for one thing, I'm not Asgardian. And for another... We have a Hulk.

[Hulk roars and attacks Thanos while Loki swiftly dodges and gets Thor out of the crossfire]
