Avengers: Infinity War2018

[As the Zen-Whoberi homeworld is being attack by the Leviathans, a young Gamora turns and finds herself facing Thanos in his full Titan armor]

Thanos:
What's wrong, little one?

Young Gamora:
My mother. Where is my mother?

Thanos:
[kneels down to Gamora.] What's your name?

Young Gamora:
Gamora.

Thanos:
You're quite the fighter. Gamora. Come. Let me help you. [Thanos offers his hand; she wraps her little fingers around one massive finger, and he leads her to a pavilion, where he crouches to her eye level again and produces a small - for him - red-jeweled handle. Pressing the switch, razor-sharp blades pop out both ends.] Look. Pretty, isn't it? Perfectly balanced, as all things should be....Too much to one side, or the other… [He balances it on one finger, overbalances it purposefully and catches it.] Here. You try.

[Thanos hands Gamora the dagger - the handle is two child-palms' widths in length. She tries balancing it on her index finger.]
