Death Note Episode 25 Breakdown: Minute-by-Minute Breakdown of L's Fall
What is L Lawliet's true name and how did Rem know it?
L's real name is L Lawliet, confirmed in the official companion volume *Death Note 13: How to Read*. Rem knew his true name and lifespan instantly by using her Shinigami eyes, which allow a death god to see any human's identification simply by looking at their face.
Could L have avoided death by writing his own name first?
In the canonical manga and anime series by Tsugumi Ohba, L does not write his own name. In the 2006 Japanese live-action film adaptation *Death Note: The Last Name*, L writes his own name into the notebook first, specifying a peaceful death 23 days later. This preempted Rem’s writing, allowing him to survive long enough to expose Light as Kira.
Why didn't the Task Force see Light smiling as L died?
Light carefully angled his body as he caught the falling detective, turning his back toward Soichiro Yagami, Matsuda, and Aizawa. His face was only visible to L, who was staring upward as his vision faded.
Did Rem die immediately after writing L's name?
Yes. Because killing L and Watari directly prevented Misa Amane's capture and eventual execution, Rem's actions prolonged a human life out of affection. The moment the names took effect, Rem disintegrated into a pile of grey ash, leaving only her notebook behind on the floor.
