Flash didn't have powers on The Flash S02E19, but has powers at the end of Arrow S04E19 just one day later. How is that possible?

The answer is probably a plot hole or to not completely trust episodes order between those shows (although it was accurate since Barry appeared on Arrow in the 2nd season). Or did I miss something?

Unfortunately, there's not enough in-universe clues to sync the shows up, but most likely the answer is that Flash and Arrow are out of sync. There's a slim chance a future Flash episode will refer to this event, and we'll know for sure, but probably not.

This isn't unusual, and in fact, the exact same thing happened last season. At some point, Flash ended up out-of-sync with Arrow, and Felicity and Ray appeared as a couple on Flash, trying to figure out the ATOM suit, at a point where that made no sense on Arrow. Similarly, it's very difficult to fit the two season finale crossovers (specifically, Oliver being in Central City, in League armor) into their respective timelines, and no hint was given how that was possible.

The most reasonable explanation is that Arrow is lagging behind Flash, and this funeral and related events took place before Barry lost his speed.

  • Maybe they are not lagging but are far ahead.

A Few episodes back the Arrow showed Oliver and Barry standing by the grave with caption that said 6 months later that might mean something

    Yes, it means Arrow s04e01 was six months before s04e19. That doesn't explain if Flash is also exactly the same schedule.
