This episode was an improvement towards plot, action and storyline but as for everything else that doesn’t matter all what I will say is that it literally is a huge improvement. I really liked that they brought in the speedsters grim reaper Black Flash in this episode. I mean I know they said Black Flash was going to be showing up in the Flash, Supergirl, and Legends of Tomorrow (which he already has) of the Arrowverse. But everything of the episode was amazing and seeing all the faces that died in season 1 and 2 brought back memories and feels so much.
In this episode: Barry (Grant Gustin) decides to go into the speed force to get Wally (Keiynan Lonsdale) out of it. H.R. (Tom Cavanagh) comes up with a idea to help Cisco (Carlos Valdes) to create a device that tracks Barry’s movements while hes in the speed force. After Cisco creates the device and implants it onto Barry’s lightning symbol he vibes him into the speed force. Barry then wonders what seems to be CCPD in his CSI lab. Barry wonders around only to see the speed force taking the form of Eddie Thawne (Rick Cosnett) Eddie asks Barry why he has come into the speed force again. When it learns Barry’s intentions of saving Wally from the speed force, the speed force tells Barry that its not going to be as helpful and kind as it was last time when Barry was trapped himself.
The speed force agrees to tell Barry where Wally is but he has to outrun a time wraith first, when Barry outruns the time wraith Barry is then transported into another room thats similar to Star Labs. Barry then sees Caitlin (Danielle Panabaker) holding a baby; Ronnie Raymond (Robbie Amell) baby. The speed force cloaked as Ronnie now tells Barry this is the life Ronnie should’ve had but instead because of Barry, Ronnie was not gifted that life. Barry then figures out what the speed force is doing cloaking itself as people who Barry felt responsible for hurting or killing to make him realize Iris (Candice Patton) fate is his responsibility not Wally’s. When Barry tells Ronnie he’s going to get Wally out of the speed force, the speed force unleashes Black Flash. Barry and Black Flash have a chase throughout Star Labs in the speed force. Black Flash then holds down Barry draining his soul into nothing but a corpse in a last minute attempt Barry destroys the device by stabbing Black Flash.
Barry then reaches Wally, but not before hes reached with another ghost from his past Leonard Snart/Captain Cold (Wentworth Miller). Barry asks Leonard what Wally is seeing in his hell. Leonard tells Barry that Wally is seeing what is known as his own personal hell which is his mother’s death repeating in a loop for all eternity. Barry demands Leonard to let Wally out but he refuses. Leonard then asks Barry if he would like to know why Leonard sacrificed himself to save the Legends. Leonard goes on saying he wanted to be like Barry to be a hero. When Barry still tries to get Wally out, Leonard freezes him to the wall. In a save moment Jay (John Wesley Shipp) saves Barry from the attack only so Barry can return the favor in saving Jay from Leonard. Barry then gets Wally out but at a cost, Jay had to stay in the prison room of the speed force. Barry and Wally return out of the speed force.
In the end of the episode: Barry tells Iris he thinks they need some space, realizing that its now his responsibility to save Iris from Savitar, not Wally’s.
