At the end of The Flash’s third season, Barry (Grant Gustin) had no choice but to trap himself in the Speed Force in order to save Central City.
The first season 4 trailer has surfaced at San Diego Comic Con and by the looks of things Iris (Candice Patton) is dealing with her grief by taking control of Team Flash. Wally (Keiynan Lonsdale) and Cisco (Carlos Valdes) are keeping the city safe and it looks like Caitlin (Danielle Panabaker) is back in the fold.
Julian (Tom Felton) and Wells (Tom Cavanagh) are both suspiciously absent from the trailer and Barry himself makes only a fleeting appearance as the team tries to save him.
The trailer also teases the arrival of a new big bad in the shape of a supernatural Samurai who threatens to destroy the city if Barry isn’t handed to him.
We’re pretty sure Barry will get out of the Speed Force fairly quickly but what repercussions it will have remains to be seen.
