Ep 20. Genesis

Oliver Queen has been through a lot in his life. As Arrow season four episode 20, titled "Genesis," begins, he's dealing with the aftermath of his latest battle, which left one of his teammates in critical condition. But as he works to help his friend recover, he begins to realize that something much bigger is happening.

Oliver's suspicions are confirmed when he learns that HIVE, the shadowy organization he's been battling for several seasons now, is planning something major. Specifically, they are working on a project called Genesis, which aims to essentially wipe the slate clean and start over with a new world order.

As Oliver and his team work to unravel the mystery of Genesis, they discover that it involves a series of underground bunkers designed to weather catastrophic events. But when they investigate further, they find that the bunkers are not what they seem. In fact, they are being used as part of HIVE's plan to remake the world in their own image.

With time running out, Oliver and his friends must race to stop HIVE and prevent their plan from coming to fruition. Along the way, they face some tough choices and difficult sacrifices, as they try to figure out what it really means to be a hero.

One of the major themes of this episode is the idea of legacy, and what kind of world we want to leave behind for future generations. As Oliver grapples with his own legacy, he realizes that HIVE's plan for Genesis is not about creating a better world at all, but about preserving the power and control of a select few.

The episode also explores the idea of what it means to be a hero, and whether that label is earned through actions or simply bestowed upon someone because of their abilities or status. Characters are forced to confront their own values and beliefs, and make choices about what kind of heroes they want to be.

There are also hints of romance and personal growth, as some characters begin to question their relationships and prioritize their own happiness and fulfillment. As always, the action is fast-paced and intense, with plenty of fights and explosions to keep things exciting.

Overall, Arrow season four episode 20 is a thrilling installment in the series, with high stakes and compelling character development. It sets the stage for the upcoming final episodes of the season, and leaves viewers eagerly anticipating what's to come.
