Yep, but like I wildly speculated earlier, if the song for the next flash is Dogfight then it would make sense.
Andrew mentioned that we were entering the "Brown zone" which seems to indicate that the EoA flash will use another Malcolm Brown song, so that leaves out Dogfight. That being said, I wouldn't completely discount the possibility that there will be stuff with the trolls or B1 kids in the flash. They have slowly been making their way back into the plot with this act. Which makes sense as the Trolls first showed up in Act 3, which this is counterpart to. I think it'll probably focus on the B2 kids and likely uu though.

I finally believe it. This is not butter. And I know deep down in my heart that I must become butter atheist.
