In the Flash season 3 finale, we saw Barry Allen left Central City & his loved ones behind and went into the speed-force with his mother. After they defeated Savitar with the help of Jay Garrick (Henry Allen dopple-ganger), 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.
As San-Diego Comic-Con is approaching, WBTV released the official synopsis of premiere episodes of all the superhero shows. For “The Flash” Season 4, it goes like this:
“Running up against an evil time remnant version of yourself is something no one should ever have to do, but that’s exactly what faced Barry Allen (aka The Flash) as he fought to save the life of fiancée Iris West from the God of Speed known as Savitar. Barry’s victory was short-lived, however, as an unbalanced Speed Force began to wreak havoc on Central City, forcing Barry to sacrifice himself for the greater good. With The Fastest Man Alive now trapped inside an extra-dimensional energy, and unknown dangers lurking in the shadows, it will be up to Team Flash to free Barry from his own personal Hell”.
The synopsis doesn’t say a word pointing to the possibility that Barry may turn to the dark side and become a villain. Many TV show analysts have said that a comic-book storyline where once Flash returned to the land of the living after Speed Force afterlife, he started killing fellow speedsters with a mere touch. In fact, Barry Allen placed his hand on Savitar’s shoulders and reduced him to ash. The term “personal hell” has been used for Barry’s stay at the speed-force, but he was accompanied by his mother Nora Allen, so how could it be a personal hell for him?
Well, let’s wait until October to find out all the answers. CHEERS!
