You have a soul. I don't think a whole and complete one, but part of one at least.

[She didn't think anything could live without one. Even them. She knows they aren't an entire person, even if they're very close, but they have souls.]

That's your heart. I have one, too.

[She puts her hand on her chest, over where here heart beats. She can feel it.]

If we didn't have any soul at all, we wouldn't have beating hearts.
