Spoilers below for viewers who aren't caught up on The Flash's latest episodes.
The Flash has already reached its Season 4 finale, and fans are somehow still in the dark about Team Flash's final battle against The Thinker, without even a general idea about how or where it could even happen. (Speedster villains allowed for slightly easier predictions in that respect.) Showrunner Todd Helbing had previously used Christopher Nolan's blockbuster Inception as a comparison point for "We Are The Flash," and he has now expanded upon that point, explaining that Barry is about to get all up inside Clifford DeVoe's head, thanks to his wife Marlize. According to Helbing:
Personally, I am always pumped when The Flash goes off the beaten path and spends an episode experimenting with different concepts and settings than what we're used to. And I am pretty sure "sending Barry's consciousness into that of a seemingly all-powerful megalomaniac" counts as launching off the beaten path. It also makes the Inception inspiration all the more understandable, and I cannot wait to see the surprises waiting to be found inside DeVoe's dark matter-infused headspace.
While Inception was a rather complicated heist movie set inside multiple dream levels, The Flash's finale won't be quite so complex, with only the titular hero and the season's big bad engaging in this final (or not) showdown. (And there will be an all-around lack of Leonardo DiCaprio, as it goes every week on The Flash.) Still, we know Clifford DeVoe's mind will not be easy to figure out, especially if Barry is looking for a sign of goodwill that doesn't even exist anymore. I mean, The Thinker has been ported through several different metahumans' minds already, using the last one to reform his entire being back to how he originally looked. There's so little left of DeVoe's 1.0 that it's hard to imagine anything virtuous still surviving.
Of course, the love between Clifford and Marlize DeVoe is probably still too strong to just throw away forever in a season finale like this. And as Todd Helbing put it to EW, viewers can definitely expect to see some key emotional moments mixed in with some of the show's biggest special effects sequences to date. (And hopefully some Killer Frost resolutions to go along with the Mystery Girl reveal.) Here's how Helbing compared "We Are The Flash" to past finales.
The Flash will end Season 4 with its mind-expanding finale on The CW on Tuesday, May 22, at 8:00 p.m. ET. To see what other shows will be around when the Scarlet Speedster is on break, head to our summer premiere schedule.
