We're in swimming pool. It's empty except for us. I'm floating in the water, and L is a chain's length away, resting half-submerged on a circular float. I shiver, and duck my head under the water. L brought us here, in his words, for a "brain boost". Something about cerebral fluids. It's nonsense most likely, but I don't mind. I've always enjoyed the pool, and it's been a while since I've been in one.

I dive underwater, and swim underneath L's dangling foot. I consider grabbing it. Then I do, my hand wrapping almost all the way around his pale sole. He tries to kick me off, lightly, and I relent because I'm running out of air.

I float up to the surface, head popping up to reveal everything above my nose. I stare at L. He's still lying with his head back and eyes closed. I sigh and create a bubble of water.

"I am Kira." I say into the pool. I wait for a response from L. None. "L smells." No response. I sigh again. This is childish.

Then I think about diving underwater again, under L, and pulling his neck backwards, down into the blue. I shiver out of my thoughts.

Then I dive.

L can no doubt feel the chain's position moving through the water, gliding, rattling on his wrist.

I'm sure he's aware of everything that's happening.

I'm underneath him now, and I look above to the float, to where his neck should be lying. His fingers are floating nearby and I reach out to touch them, only stopping by an inch. I pull away, and look back towards his neck. I start reaching up, hands parting the surface in smooth lines.

And then I push forward, messily. In one movement, I encircle his neck, and pull backwards and down, lifting him over the front of the float.

Watari no doubt sees this from the sidelines, L's body being pulled under to disappear beneath the surface.

As it stands, I already have less air than him. My feet touch the floor of the pool, and L's feet reach towards the surface. I put my face close, next to his, and see that he doesn't have much breath.

It must have been the surprise. I think about letting him go, but I still have some air. My arms tighten around him, even though he isn't struggling in the slightest.

He isn't thrashing like I thought he would. In fact, he's eerily still, besides the look in his eyes. It's as subdued and black as always, with just the slightest glint of something. Something like fear.

I'm starting to go a little back around the edges and decide this is enough. L is still surprisingly conscious.

I release him to float upwards, and I stay on the bottom, waiting for the chain to pull me up. It does, but not very much. I push myself the rest of the way up, sliding along L's body to break the surface.

Just barely after my head is free, and before I can take a breath, L has the chain around my neck, my back to his chest.

"What was that?" He asks, calm as ever.

"An experiment." I rasp. The chain tightens.

"That isn't like the Light I know. He wouldn't do anything to raise his suspicion."

I stay silent. I glance over to Watari, who had stayed on the sidelines the whole time. Overconfident? I might not have let him go. I might have killed him.

"What were you trying to do?"

"See what you'd do. Nothing, apparently."

"Apparently." He releases me, and I take a full breath. Soon there is a tug on the chain. L is leaving the pool.

"We're going back."

"Did I spoil the fun?"

"Yes."
