While much of this season of The Flash has focused on the oddly-reimagined Savitar and his threat to Iris Allen’s future, most long-time fans have been eagerly awaiting the two-part continuation of Gorilla Grodd’s story.  The first episode, “Attack on Gorilla City,” was a bit underwhelming (partly because of effects, partly because it felt rushed).  The second part, “Attack on Central City,” airs next week and brings the fight home.  Here’s the trailer.

Lots of speedsters running around (including a recently hinted-at fourth speedster from another Earth).  Hopefully the episode will build well and move the season forward in good ways.
