Extended trailer for ‘The Flash’ reveals more Earth-2, Killer Frost, and Zoom

In this new trailer for the second half of “The Flash” season two, Barry comes face to face with friends, villains, the Reverse Flash, and Zoom. 

If I could tagline “The Flash” season two, it would be “the season of surprises,” because every episode so far has dropped a huge bomb. Some of those plot bombs have included the existence of Earth-2 and other parallel worlds, the faked death of Iris' mother Francine, the arrival of Joe's son Wally, the death of Ronnie Raymond, and the vibbing metahuman powers of Cisco. 

In the new season two return trailer,  even more shocking moments are teased, including the return of the Reverse Flash, the kidnapping of Patty Spivot, Barry and Cisco's trip to Earth-2, and the alternate versions of Caitlin Snow and Ronnie Raymond, who turn out to be the criminal metahumans Killer Frost and Deathstorm.

The trailer also provides some clues as to Barry's visit to Earth-2.  If Jay is the speedster on that earth, what happened to Barry the night the particle accelerator exploded? It appears as though Earth-1 Barry goes undercover as the other version of himself, and comes face to face with an Iris who loves him. Are he and Iris married, like they were in the comics? Will he meet the other version of himself? Will he see his mother?
