Tonight brings another episode of The Flash on the CW.   I was recently talking TV with a student who, like me, is pleasantly surprised by how quickly the “Reverse Flash” storyline has been moving.  We are both wondering, though, what could happen once the story is over, as it’s the kind of thing some series would tease forever.

Here’s the trailer for tonight’s episode:

I must admit to being pretty impressed with how well the writers have integrated the casts of The Flash and Arrow.  I tried Arrow for The Flash‘s sake, and I just couldn’t do it.  This kind of bleed-over coupled with the promise of a thirteen episode ensemble-cast spin-off next season makes me think that something really big could be in the works.

And all this time, for so much of this season, Grodd has just been creeping in the background . . .
