Episode 3 for the most part really illustrates to us again the balance between both sides. Every time L uncovers another crucial piece of evidence and you think that he has gained the upper hand, you find out that Light was actually not as reckless as you originally thought. Each side seems able to anticipate the other side's actions, making it difficult to tell who is really chasing whom. Each side has an edge in this truly masterful duel, and either one can convince you that they'll be the one that ultimately ends up on top.
