What episode of death note does L chain himself to Light?

L never chains himself to Light in Death Note. That's a common misconception, likely stemming from the dramatic nature of the anime's visuals and the intense rivalry between the characters.

While the idea of physically chaining L to Light is a thrilling one, it never happens in the series.

However, L does employ many psychological tactics to keep Light under constant observation and pressure. He uses surveillance, psychological manipulation, and even risky gambits to try and expose Light's true nature.

You can find L's meticulous investigation and cunning tactics throughout the series, especially in the episodes where he directly confronts Light.
