With the second season drawing to a conclusion, what have we witnessed in the season to date and what can we expect in season’s finale?

The Flash AKA Barry Allen is something of a comic book veteran having appeared regularly in print since 1956. In this TV adaptation, broadcast originally on the CW network in 2014, Barry Allen wakes up several months after he was struck by lightning and discovers that he can now harness the power of super speed. Barry Allen becomes “The Flash” the enemy of all criminals in Central City, joined by a team of dependable sidekicks.

The second season begins six months later, Barry now operates on his own to avoid hurting any more of his friends and family. He is attacked by a metahuman sent by an entity known as Zoom, a mysterious inhabitant of a parallel dimension.  As the season unfolded, eventually Zoom himself arrived from the parallel dimension intent on invading Central city with other metahuman nemeses. We discover that two versions of the planet exist, the world inhabited by the Flash known as “Earth-1” and the alternative universe “Earth-2”.

Zoom and his malevolent cohorts are using the breaches to travel between the parallel Earths. The team learns that the Flash, Cisco and most of the gang’s cohorts have doubles inside the parallel universe of Earth-2. There are also for the hardcore fans throughout the season some intriguing crossovers with CW Network’s “Arrow”. In Episode 8, “Legends of Today”, Barry and the gang take temporary refugee with Oliver Queen (Arrow) in Star City.

As season 2 reaches its conclusion the team struggles to discover the solution to defeating Zoom once and for all.  In the episode “Rupture”, Zoom arrives back on Earth-1 resolved to take over Central City. Cisco learns that the Earth-2 villain Rupture, his brother’s doppelganger, has  arrived on Earth seeking revenge.  In the Kevin Smith co-written episode “Runaway Dinosaur” Barry loses his powers and to regain them must confront the living incarnation of the Speed Force.

In the remaining episodes of the season we can expect Zoom to unleash an army of Earth-2 meta-humans.  In another connection to “Arrow”, Black Canary’s doppelganger makes an appearance, known on Earth-2 as Black Siren. Black Canary (Laurel Lance) was a series regular in “Arrow”.

The final episode of the season Episode 23 will premier on May 24, 2016. Season 3 has received the greenlight, with Kevin Smith returning to direct the first half of the season’s episodes. A release date for Season 3 has not been officially announced, but principal shooting will be taking place in July and August.
