Warning! The following contains spoilers for Episode 12 of The Flash Season 9, called “A New World, Part Three,” and the preview for the finale, “A New World, Part Four.”
The Flash is just one episode away from closing out the series, and The CW show is going all-out. It looks like Grant Gustin‘s Barry Allen will go head-to-head with some of his worst enemies, as Eddie Thawne‘s transformation into Cobalt Blue will bring some other notable characters from the past to Central City. Tom Cavanagh will return as Reverse-Flash, and I’m absolutely psyched about who else we’ll see in the series finale based on the trailer.
