First I watched Season 1 Episode 22 "Rogue Air" Cisco discovers that Wells has been supercharging his speed while he sits in his wheelchair, which is why he is so much faster than Barry. The particle accelerator is activated and the team realizes that Wells has been at S.T.A.R. Labs the entire time and he has repaired the accelerator. While investigating, Wells escapes but the team is able to find and rescue Eddie, who is disillusioned after Wells showed him that Iris marries Barry in the future. Eddie later tells Iris what he knows of her future and ends their relationship. Worried that when the accelerator reaches full power the metahumans imprisoned inside will be killed, the team decides to relocate them to the A.R.G.U.S. prison on Lian Yu. In order to set up a safe transport, Barry is forced to go to Leonard Snart for help. Snart agrees but only after Barry erases Snart's criminal record and history from the CCPD database. Snart sabotages the transport and allows the metahumans to escape. Wells arrives back at the lab just as the accelerator fully charges. Barry, Ronnie, and Oliver all meet outside to fight Wells. After each tries battling Wells individually, they coordinate efforts and Oliver finally stops him with a nanite injection that disables Wells' speed.
Anyways I enjoyed the episode but halfway through it I kept thinking to myself... when is the big battle happening but then would remember that this wasn't the finale, but only the second to last episode. But at the end of this episode I did get a somewhat "big" fight between The Flash and Reverse Flash, with the help of Arrow and Heatwave and that was pretty awesome.
The Flash on the other hand has had nothing but fun (though dark at times) episodes. This finale was awesome. Barry finally gets to go back in time to save his mother but then is told by his future self to not do it so he allows his mother to be killed. I am happy to say that Barry does get to be with his mother as she dies in his arms.. it brought me to tears.
And just when you thought it was over... the blackhole reappears and Central City begins to get sucked up into the abyss. Though the odds are against him The Flash has to try and close by the hole by running really fast but they way they did this scene was amazing. He ran up a crumbling building and then started hopping from debris to debris to get to the center of the black hole before the screen went black and the episode was over.
I can't wait for more of The Flash, Arrow and Legends of Tomorrow on the CW. DC really knows how to make some amazing TV.
