With bigger things on the horizon for The Flash and Barry’s time-traveling secrets outed to the superheroes of the Arrowverse in last night’s episode, one has to wonder: is that all audiences will get?

David Ramsey has repeatedly made it clear that Diggle will be fairly balanced in his response to Barry’s altering the timeline, worrying more about Barry misusing his massive powers than his own personal loss. Still, last night’s episode — in which everyone was briefly angry at The Flash, then forgave him when he came in to save the day — didn’t feel like it gave the character much of an opportunity to process the news at all — or any of the team a chance to deal with the fact that Felicity had that information for weeks and didn’t reveal it.
“Arrow‘s mid-season finale, there’s actually a fair amount of discussion about Flashpoint, given the fact that you know, essentially, the crossover outed Flashpoint to the Arrow characters besides Felicity,” said Marc Guggenheim. “They deal with sort of, I think in some humorous ways actually, deal with some of the ramifications. For example, I think Curtis is concerned that maybe he was straight originally, as one example.”
So — next week’s Arrow midseason finale will give Team Arrow a chance to respond to the craziness of “Flashpoint” as well as the “Invasion!” crossover.
Arrow, The Flash, and Supergirl will cross over with DC’s Legends of Tomorrow this week in “Invasion!” a three-part crossover that starts in the final moments of an episode of Supergirl and then plays through the other series. Based on the 1988 comic book event miniseries Invasion! from Keith Giffen, Bill Mantlo, Todd McFarlane, Bart Sears, and the crossover — with its marketing title “Heroes vs. Aliens” — will closely track the plot of that storyline: aliens will be assembled by The Dominators and descend on Earth to bring an end to the “threat” of Earth’s burgeoning metahuman community.
In the comics, the Dominion were secretly hoping to build their own super-race, and as a result created a handful of new superheroes in the course of the story.

In the TV version, rather than assembling a loose alliance of dangerous alien races, the Dominators will apparently be mind-controlling the aliens that join them. That’s a revelation that suggests even the heroes might be forced to take one another (or at least the alien Supergirl) on at some point in the story.
