She changed plans and wants to go swimming

Aria stops you and says, "We are not going hiking. We are going swimming."

She leads you to the lake.

You can see that there is a big rocky island in the middle of the water.

"Here. Get in."

She pushes you towards the water, and you walk into the water.

It's cold, but not too cold.

You dive in and start to swim.

The water is completely clear, and you are amazed at the amount of fish swimming around you.

You see tiny little fish that are only the size of your finger.

They swim around you as you swim through the water.

The water is fairly deep, but you don't notice anything about it.

You look at Aria.

"Do you know where we are supposed to go?"

She stops in the water and looks at you.

"Yes, we are supposed to go to the island."

She points towards the rock in the middle of the lake.

You see the rock, and it's small.

It looks like it is barely large enough for you to walk on.

You swim towards it, and Aria follows.

You make it to the rock, and Aria stops.

"Do you know what this is?"

You look at her and don't say anything.

"It's a rock. I know that much."

Aria stops and looks at you.

"Do you know why we are here?"

"To swim?"
