Steven Universe, Season 1

Steven:
I don't get it! I thought I almost had it.

Pearl:
Nobody expects you to be able to perform fusion right away, Steven.

Amethyst:
Yeah! It's really hard, even for us.

Garnet:
Not for me.

Pearl:
We'll keep working on the dance for now, and who knows, in a few years... I wonder though if Steven's body is capable of fusion. Fusion merges the physical forms of Gems, but Steven is half-human. He's organic.

Steven:
Organic?

Amethyst:
Aw, come on! It's Steven! Who knows what's gonna happen? [laughing out loud]

Garnet:
Well, I think Steven can do it.
