With DeVoe’s Enlightenment due any day now, Team Flash needs a way to stop The Thinker’s satellites from turning the entire world into “dumb dumbs” like Harry Wells. Because DeVoe’s Kilg%re powers mean he can thwart any technological attacks, they need something that doesn’t involve tech. Their only option is to track down Amunet Black, who’s been missing ever since the prison break when she sold a handful of bus metas to DeVoe. And if her return reminds us of anything, it’s that her quirky, uneven personality is the perfect antidote to the severity that’s befallen Team Flash. The Flash should totally make her a series regular.

Spoilers follow for The Flash Season 4, Episode 21: “Harry and the Harrisons”

With only two more episodes in Season 4 after this one, “Harry and the Harrisons” felt like a bit of a filler episode, especially without an exciting appearance from everyone’s favorite mystery girl and not even a peep out of DeVoe himself. Caitlin is still trying to figure out if Killer Frost is really gone, and Harry is struggling with his diminishing intelligence, going so far as to make a brand new Council of Wells. But ultimately, the best thing this episode does is remind us just how cool Amunet Black and her powers are.

Since Amunet first debuted earlier this season, Battlestar Galactica alum Katee Sackhoff has been a total scene-stealer whenever she shows up, playing a quirky kingpin-type villainess with an unhinged personality. Sure, meta-human trafficking is a pretty serious crime, but after DeVoe ruined her whole operation, she’s resorted to illegal gambling clubs. And now she even teams up with Team Flash. She struggles to abide by Barry’s “no killing” rule, but that doesn’t stop her from slicing off Norvok’s snake eye.

For most of Season 4, The Flash used Ralph Dibny as a comedic counterpoint to Barry’s seriousness, trying to infuse the show with a bit of levity. But with Ralph consumed by DeVoe and his powers used to give DeVoe his original body back, Team Flash is back to being super-serious.

What if Amunet was a series regular, struggling against Team Flash’s attempts at rehabilitating her? Watching her waltz around S.T.A.R. Labs critiquing everything was a delight, which is to say nothing of her incredible Magneto-like powers. There’s also something refreshing about the prospect of a non-millennial potentially joining the team, especially considering her somewhat maternal affection for Caitlin.

Sadly, Amunet merely left Caitlin with a mystical meta-human hand grenade from her special metal, a MacGuffin of sorts the team can be use to prevent the Enlightenment before it happens. On to the penultimate episode next week.

The Flash Season 4 airs Tuesdays on The CW at 8 p.m. Eastern.
