The premiere of Flash season 4 attracted good viewership but it was not record-breaking. This season is slowly building the momentum as Barry is reborn faster and powerful than ever. At the end of last season, the speed-force became extremely volatile and unstable, led to massive earthquakes that wreaked havoc upon the common folk. It required a powerful speedster to stabilize the effects and Flash volunteered as he held himself guilty of creating Flashpoint timeline.
Although, the destabilization of speed-force and Barry’s surrender to prevent a major catastrophe on the Central city was a cliff-hanger of sorts but he came back in the very first episode of the new season without adequate build-up. There is a widespread consensus that the show was too quick to bring Flash back into the current timeline without any consequences.
We saw how Team Flash grappled with Barry’s disappearance and new threats that threatened the Central city. When a samurai ninja showed up with his mystical sword, Team Kid Flash ran out of ideas to stop him. He demanded the real Flash to fight him or else he will destroy the Central city. As a result, Cisco had to try out speed-force bazooka on which he has been working for months to get Barry out of speed-force. He failed initially but later CCPD found the body of Flash who has totally lost his mind after spending six months inside the speed-force.
In Barry’s absence, Iris did what he asked her to do i.e to keep running. She buried herself into work and is now an important member of Star Labs to fight crime and meta-humans. When Iris gave herself up, Barry’s memories returned and he again became the fastest man alive. He told Iris that all his mistakes, sins were washed off inside Speedforce. When Barry came back, she couldn’t stop her tears rolling down as he kissed her. But it wouldn’t be a smooth ride for them as we saw them at couple’s therapy sorting out their issues.
When Barry Allen first returned to the Central city after spending six months inside the Speed-force, he was either drawing alien symbols or babbling riddles which did not make any sense. He was mumbling about Oliver Queen, stars being loud etc. which led Caitlin to conclude that he is suffering from some kind of Dementia as he spent 10,000 years not just 6 months into the speed force. As the Speed-force transcends time, it is quite possible that he saw glimpses of both past and future. He recalled the death of his mother which confirmed he saw the past.
In fact, there is a fan theory which points to a particular line where he said:
“We are going to need more diapers”. The theory concludes that Barry and Iris will get married and they may have children who would need diapers. Fans are suggesting that Iris may have twins which are a twist that is taken straight from the comics. The twins are known as Tornado twins namely Don Allen and Dawn Allen.
On the other hand, we got a sneek-peek into this season’s big villain called “The Thinker” played by Clifford DeVoe who is extremely calculating and would be terrifying than Barry’s former adversaries who were all speedsters. The Flash knew how to deal with his kind but “The Thinker” is the fastest mind alive who will hit him hard and he would not even realize that he is down.
Guess what…there is a profound connection between Barry’s drawings and Thinker’s face (look below his eye). If we look closely the markings on his face, they are similar to what Barry was scribbling on the wall of C.C.P.D and Star Labs. It is possible that “The Thinker” has a connection with Speed-force and both Flash and Thinker draw their powers from the same source. The speed-force can help you become a speedster and move at breakneck speeds but it can also help you become “fastest mind” alive by allowing you to absorb massive amounts of information at a much faster rate.
Well, we will find out about the connection in the upcoming episodes but whatever it is “The Thinker” will prove to be the worthy adversary that Flash will find it extremely hard to beat.
