DISCLAIMER: swim4life4ever does NOT own Death Note. Or Portal.....

L sat in front of the computer screen, his eyes glued to the screen, his hands flying over the keyboard. Light looked at him.

"L, what are you doing?" Light asked, curious, tearing his own eyes away from his work screen.

"I'm working for cake, Light-kun." This intrigued Light. On L's screen, he saw what seemed to be a typical first-person shooter game. The gun, however, seemed to shoot portals, rather than bullets. The mechanical voice said,

"While it has been a faithful companion, your Companion Cube cannot accompany you through the rest of the test. If it could talk - and the Enrichment Center takes this opportunity to remind you that it cannot - it would tell you to go on without it, because it would rather die in a fire than become a burden to you."

Light shivered at the voice. What kind of demonic game is this?

"Goodbye, Companion Cube. You were helpful, caring, and got me through this elongated stage in the game. Your sacrifice only gives me more reason to find the cake and avenge your fallen grace." L said solemnly as he placed the hearted cube into the incinerator.

L continued to play through the multiple levels, completing them with grace and speed.

Finally, he reached the level with the sign indicating cake was at the end.

With a determined face, L sped through the levels, not mis-hitting a single key.

Finally, he loaded the final platform

"Congratulations, the test is now over. All Aperture technologies remain safely operational up to 4000 degrees kelvin. Best assured, that there is absolutely no chance of a dangerous equipment malfunction prior to your victory candescence. Thank you for participating in that Aperture Science Enrichment activity. Goodbye!"

"Like hell I'll let you incinerate me!" L proclaimed, evading the fiery pit of death. After safely getting away from the test room, a series of labyrinth-like hallways, corridors, and rooms were placed in L's way. I had no idea what he was even looking for, although I assumed we were finding this mechanical beast.

However, I think L just wanted the cake.

Finally, L reached the room with a giant computer-like system hanging from the ceiling.

After several pieces of dialogue, L placed a talking sphere into an incinerator.

"Good news. I figured what that thing you just incinerated did. It was a morality core they installed after I flooded the Enrichment Center with a deadly neurotoxin, to make me stop flooding the Enrichment Center with a deadly neurotoxin. So get comfortable while I warm up the neurotoxin emitters."

"Sure, sure. If it can kill me in time, which I highly doubt. I WILL get that cake!" L started rapidly dismantling the machine, a timer appearing on the screen.

In what Light believed to be record time, L destroyed the machine. The premises exploded, leaving the character outside, the remaining story unknown.

Suddenly, a clip played of Companion Cube and a piece of cake on a desk and then cut to the credits.

"NO!" L cried. "It's can't be true, it can't be!" Light looked at him.

"Ryuzaki, why are you do upset? You beat the game!" Light shouted.

"Light-kun, in a previous level, a hidden part said 'The cake is a lie', which I presumed to be a lie meant to deter those who would so easily accept it. But I was WRONG!" L pounded his fists on the desk in rage.

"I'm sorry....?" Light said hesitantly.

"The cake is a lie...." L said, flopping his head on the table.
