And Michel knew he was seeing only the tip of the iceberg.

She could see the tip of a tree up there.

Then he saw the tip of a tail, sticking out from under the Council table.

She saw so clearly the tip of her foil against his heart.

And do you see the tip of that hill over there?

I saw the tip of his tongue for a second.

This is an iceberg and we have only seen the tip of it.

You only ever see the tip until it's too late.
