Things are going to come to a head in 'The Flash' finale, which is going to end on a nerve-wracking cliffhanger. And the worst part is that due to the coronavirus pandemic, we don't know when the production will resume again. And so, many of our questions for Season 7 are going to remain unanswered for quite a while.

Previously, we saw Barry Allen (Grant Gustin) fighting Mirror Iris (Candice Patton), who went all Terminator on him. Even though he managed to connect with her emotionally, she was killed by Eva McCulloch (Efrat Dor), who escaped from the Mirrorverse with a little help from Bloodwork. In the upcoming episode, Barry struggles to fight Godspeed with his remaining power, which really isn't much.

However, in the finale, it seems as if Iris is still trapped in the Mirrorverse and Barry hasn't created an artificial speed force yet. And, he makes a risky plan to rescue Iris. s. 

The synopsis of the episode reads, "Barry (Grant Gustin) considers a risky plan to save Iris (Candice Patton) from the Mirrorverse. Ralph (Hartley Sawyer) attempts to stop Sue (guest star Natalie Dreyfuss) from making a grave mistake that could destroy her life. Phil Chipera directed the episode written by Kelly Wheeler & Lauren Barnett."

So in short, Arrowverse fans are going to have their hearts in their mouth, for this episode. 'The Flash' Season 6 had to be forcibly cut short due to the pandemic, and the showrunners abandoned all ideas for their planned finale. Some shockers are in store for us in Season 7, as if we weren't already on our toes.

It has been a tough and chaotic season for Barry, who had to deal with the Crisis, numerous sinister villains like Bloodwork (Sendhil Ramamurthy) Ragdoll, Black Hole and the return of Reverse Flash (Tom Cavanagh) as well as the death of the Speed Force, which is just the cherry on the cake of this meltdown. 

So let's see what happens in this finale. Will Barry and Iris reunite? And at what cost? Tune into 'The Flash' on Tuesdays at 8 pm on The CW.
