The entire episode is the climax to the best saga of DBZ. Both Gohan and Cell are locked in an intense beam struggle. We see Goku cannot step in to save the day as he usually does and instead motivates Gohan telepathically. His guidance and support really captures the relationship between father and son. Goku's words are extremely moving. As Cell gains the upper hand, every character left standing has their chance to shine, starting first with Piccolo who shows how much he cares about Gohan when he steps into the fray despite having no chance of beating Cell. His admirable example leads Tien into the fight also, uttering "He (Piccolo) didn't think he could (take on Cell) but he tried to anyway." This is possibly a callback to Tien's big moment in "Sacrifice." Krillin and Yamcha are also moved into action by these words. It's a great life lesson. Even when the odds are stacked against you, never give up, never give in. Despite the overwhelming difference in power, you could see Cell was getting infuriated with the Z Fighters. His epic lines "They just keep lining up to die!" and "AAH! No chance! You have NO CHANCE!" adds to the tension. Meanwhile the episode still has room to show us Vegeta's internal struggle. At first he scoffs at the Z Fighters for even attempting to fight Cell, but as he quickly realizes that their plan might actually work, he is held back by one thing: his pride. Just as Gohan is about to lose, a powerful blast smashes into Cell, knocking him off balance. Cell looks up, surprised and who does he see? Vegeta! Its a wonderful moment for Vegeta's character to put aside his pride and help save the day not for glory but to give Gohan with... (as Goku puts it) the chance he needs to finally finish Cell off once and for all. The viewer is treated to a blinding ray of light and an epic one handed Kamehameha walk as Gohan unleashes his full power to destroy every last cell of the diabolical android for good. This episode is a treasure in both DBZ and anime history and will never be forgotten.
