The Flash season 6 episode 19 is arriving next week on The CW, with the title "Success Is Assured." This will be a significant episode as it serves as the season finale of the series. It was not meant to be the original conclusion, but there are still a lot of stories worth-exploring here.

The Flash season 6 episode 19 will see Barry doing whatever he can to save his wife Iris, who was trapped inside the Mirrorverse for most of the second half of the season. But then, getting his wife back wouldn't be that easy and he recognized that there's danger along the way.

In the synopsis, Barry is considering a risky plan to save Iris from the Mirrorverse. Based on the promo, this is not an easy mission for him and saving his wife is harder than he previously expected. While trying to do his best to bring Iris back, Barry may encounter Mirror Mistress.

Eva becomes a huge part of the season 6 finale and could bring threats to the Team Flash members. Her version of Mirror Master, however, is different and she goes by the name of Mirror Mistress. It seems like there could be a big showdown between Barry and Eva within this episode.

Barry's top priority now is to save Iris before it's too late. Getting her out of the Mirrorvese is challenging, but the Team Flash could help him with this one. It also remains to be seen whether or not Eva is just a simple foe that could be taken down easily.

As for what else is coming in The Flash season 6 episode 19, Ralph will try to stop Sue from making a grave mistake that could potentially destroy her life. While Barry and Iris' storyline is interesting, Ralph and Sue's story is also worth exploring. It's interesting to see where their story is heading now.

Although the episodes of the current season were cut short, the finale still brings some cool and intense stories. It may not be a full finale, yet it is something to look forward to. The episode could likely leave some cliffhangers that may continue in the next installment.

The Flash season 6 episode 19 will be airing on Tuesday night, May 12, on The CW. The episode is directed by Phil Chipera and written by Lauren Barnett and Kelly Wheeler.
