Yet another great episode of The Flash this week keeps me questioning what the heck is wrong with Arrow and Supergirl writers? Before we dive into tonight’s episode, let me offer a lesson. Kids, if you ever become a speedster in any universe, stay there! Do not return to the past and do not go to the future. Barry Allen did not heed the advice from Wells. Despite all the do’s and don’ts he was reminded by Cisco, it would not matter. From the get go when Barry was running through the time portal, it somehow summoned a Harry Potter ghost to follow him to the past. Team Flash had work out a best point of entry. It was the moment Pied Piper/Hartley Rathaway was on the attack. But Barry was a tad early, prompting him to knock out his old self with a tranquilizer before he continue to battled and take down Pied Piper and bring him back to STAR Labs. This time he reminded the past-Cisco to make sure the hidden explosive in Piper’s ear is remove (Previously that’s how he escape from STAR Labs). All these did not escape Thawne/Wells. Beside Barry Allen is not the greatest actor in the world. Thawne told Barry to meet him in another room and knocked him out cold and cuffed him in the time vault. It was a great scene between the two. We learned that the Harry Potter ghost is call ‘Time Wraith’, Thawne had encounter it before. It is only after future Barry. When Thawne learns of Barry came from the future, he realized his plan had failed. He does not believe Barry when he told him the sole purpose of his return is to seek his help to gain faster speed. Thawne move in for the kill but Barry convince him his return is to prevent singularity from destroying Central City. Also if anything happens to him, he already left the present Barry a letter on how to defeat Thawne that will prevent him from getting home. Just then the Time Wrath show up at STAR Labs hunting for future Barry. It chases Caitlin and Cisco into joining Pied Piper inside the meta-human cell. Time Wrath proves to be strong as he nearly broke the glass panels before Piper took the gauntlets from Cisco give a quick tweak and emit a frequency that chases it away. Just when future Barry was trying to explain to Cisco and Caitlin about the Wraith, in rushed present Barry that further confuses the situation. Thawne knows the only solution to rid of the Wraith is for future Barry to leave. Before he does that he took Barry back to the Time Vault and upload a thumb drive that contain the equation of tachyon enhancements, similar to the harness the Reverse-Flash uses and that Barry was wearing in the Supergirl crossover. Before heading home future Barry told Cisco, Piper knows where to find Ronnie Raymond. Barry heads into the particle accelerator speeding home with the Wraith trailing closely behind and interfering. Presents Barry pitch in to help future Barry to go through the time portal. Unfortunately, the Wraith follow through as well. In present day, Cisco special gun could not stop the Wraith as it begins to suck the life out of Barry, in came Hartley(Piper) using the gauntlets blasting the Wraith away. So there’s one good thing coming out of time traveling, it turn a villain into an ally that saves the day. This episode is significant because the traveling back in time inevitably changes a lot of the presence and future of The Flash. The least of which Eobard Thawne and Eddie Thawne along with Robbie Raymond might come back from their dead.
In other development. Before travel back in time Iris confess to Barry she is having a hard time starting a new relationship because of Eddie. In the short moment Barry was in the past, he managed to cajole Eddie into making a video message in the guise of a birthday wish for Iris. When Barry return to present day, he told her he found an old footage of Eddie wishing her birthday that he forgotten and let her view it. It was one of a tender moment that The Flash is good at, allowing the show to pause from all the super hero actions and let the characters to develop naturally. With that The Flash is taking another 3 weeks break. Episode 18 will air on April 19th. Check out the trailer below.
