DISCLAIMER: This recap of Harley Quinn Season 4 Episode 10, “Killer’s Block,” contains spoilers. Proceed at your peril. 

Welcome back, Harlivy lovers! I can’t believe it’s already time for the season finale, but here we are. “Killer’s Block” is a stellar season-ender in my book. It’s irreverent, raunchy, darkly hilarious and action-packed, culminating in a jaw-dropping cliffhanger, complete with a few narrative threads to flesh out in a potential fifth season. It’s peak Harley Quinn, a nice palate cleanser after a rocky fourth season. 

I’m excited to explore Gotham City Sirens in Season 5 and how Nightwing’s resurrection ties into that. Will Gordon kill Joker or just torture him? Could Talia be the Big Bad for Season 5? Will Bruce Wayne try to revive the Bat Fam? So many questions, y’all. 

Ready to delve into “Killer’s Block”? Let’s get to it.

We open with Harley (Kaley Cuoco) — who’s no longer wearing her Bat Fam costume — fighting Bethany (Krizia Bajos) in the latter’s home. Harley wants to kidnap Joker and torture him for shooting Batgirl. Initially, Bethany refuses to hand him over. However, when her children get involved, she reluctantly gives him up to protect them. We see Harley dragging a bound Joker (Alan Tudyk) out of his house during a rainstorm.

Later, Harley reunites with Barbara Gordon/Batgirl (Briana Cuoco), who miraculously survived getting shot. Of course, she’s now paralyzed from the waist down. Like a ding-dong, I thought she died in last week’s penultimate episode, forgetting her origin story entirely. Hey, I blame how convincing the animation looked. Anyway, Harley shoos Barbara’s nurse out of the room and presents her with yet another casserole. Barbara doesn’t want Harley around, though, and kicks her out. Harley spots Gordon (Christopher Meloni) sitting outside his daughter’s hospital room. He vows to avenge her near-fatal injury by finding the a-hole who did this to her.

Next, Veronica Cale (Edi Patterson), Talia al Ghul (Aline Elasmar), Livewire (Elasmar) and the other badass boss ladies of Gotham throw Ivy (Lake Bell) a party for her first takeover. Unfortunately, Ivy doesn’t allow herself to celebrate giving Lex Luthor the boot. All he did was escape to the Moon on his phallic-shaped rocket. He could return to Earth and seize control of the Legion of Doom.

Ivy concocts a plan to squeeze every drop of opportunity out of Gotham, presenting a new game plan to carry out acts of environmentally conscious evil. The gals urge Ivy to take the win. It’s all cyclical — sometimes, they’re victorious; other times, they lose. It’s part of business. Don’t rock the status quo, Ivy. Meanwhile, Harley tortures Joker at the Gotham Zoo. She tries to sick her hyenas on him. Joker taunts her, stating that she has “Killer’s Block.” It’s like writer’s block, but it happens to killers who struggle to devise new murder methods.

He asks her if she’s a villain or a hero. Harley muses she’s somewhere in the middle. Joker notes that “normies” reside in the center. Is she unremarkable? A regular Jane who’s neither a Bat Fam superhero nor a Gotham baddie? It’s all food for thought. Regardless, Joker hopes she doesn’t torture him like those A24 horror movies he loathes.

At the Legion of Doom, Harley admits to Ivy that she hasn’t killed Joker yet. She also tells Harley about Lex’s 40th birthday party (well, his 16th 40th party, according to Veronica) on the Moon. Ivy plans to crash it, hoping she can deliver a devastating (and deadly) blow against the fragile ego that is Lex Luthor. Harley accompanies her GF. We see our girlfriends arrive on the Moon with Joker in tow, who’s blindfolded and on a leash. Will he ever get that trail mix he requested earlier?

While Harley looks for a bathroom, Talia chats with Ivy about taking her anti-aging serum to the next level. Harley stumbles upon a weakened Superman (James Wolk), who looks like a living mummy in his Kryptonite cell. She learns Lex drained his energy, absorbing the hero’s powers and gorgeous hair. Not the hair and the cute little curl!

Meanwhile, Clayface (Tudyk) recreates Marilyn Monroe‘s iconic “Happy Birthday, Mr. President” routine via hologram. He couldn’t get through airport security with his emotional support capybara. Hey, it happens to the best of us. Lex (Giancarlo Esposito) pops out of a birthday cake in a green and purple Iron Man-esque suit. Sure enough, he’s got Superman’s hair. Harley leaves Superman in his cell to report her discovery to Ivy, who’s now battling it out with Lex at the party.

Unfortunately, her plant powers are no match for Lex’s new abilities. Harley leaps into fight mode and shoots Lex; however, he catches the bullet between his teeth. He tosses the pair into the closet to the laughs of the party attendees. Harley and Ivy formulate a new plan in the closet to put the haters in their place. They realize they exist on the fringes of good and evil; perhaps that’s not negative.

So, we see Harley and Ivy driving one of Lex’s Moon trucks to where his “Earth Saver” ray is. It’s time to eradicate what’s poisoning Gotham. Lex locks eyes with our pair as Ivy gives him the middle finger. Enraged, he hops into another truck to tail them. Ivy asks Harley to call Barbara (speaking of, she has to water Bab’s ficus for real, this time) to see if she can hack Lex’s truck. Barbara does so with glee (and rather quickly). She takes control of his vehicle and sends him flying into a moon crater. 

Harley and Ivy run into the room where Lex’s laser is kept. It’s also where Superman languishes in his Kryptonite cell, wasting away to nothing. Ivy aims the blaster at Earth, hellbent on destroying various institutions owned by her fellow boss ladies, such as Talia al Ghul and Veronica Cale. The ray is pretty damn precise. While en route to Earth on her own ship, Talia notices the laser taking aim at the planet. To make matters more annoying, Mark Zuckerberg’s corpse lands on her window. Sigh. We can stop tweeting that hashtag now. 

Lex Luthor wears a green and purple suit while sporting Clark Kent-like hair at a party on the Moon.

Meanwhile, Clayface loses it all at the tables at Lex’s Vegas hotel, which Ivy also blasts away. I hope he escaped. While practicing his deejaying, Bruce Wayne (Diedrich Bader) watches Gotham fall to pieces. He orders his folks to pull strings and get him an early release from Blackgate Penitentiary. His city needs Batman now more than ever.

Then, Harley and Ivy share a tender moment. Ivy reveals how Harley inspires her to be a better person. They both genuinely want to change the world for the better. Sometimes, you gotta blow sh*t up to do that. Harley doesn’t need the Bat Fam, just as Ivy doesn’t need the Legion of Doom. They can create their own organization. Meanwhile, Steppenwolf arrives and carries Lex off to Apokolips. 

Ivy’s use of the ray is demolishing Gotham and the Moon itself. We see it break apart as the birthday party attendees flee the scene. Harley saves Superman, who notes that he always knew she was a hero. However, Harley corrects him: she’s Motherf*cking Harley Quinn. That’s my girl. Harley, Joker, Ivy and Superman hop on Lex’s rocket to return to Earth.

Three days later, Alfred (Tom Hollander) finally arrives at Blackgate. He committed crimes specifically so he’d have access to the elite prison and Master Wayne. Unfortunately, he spots Bruce exiting the penitentiary, getting himself out early thanks to his connections. Now, Alfred is stuck there without him. Comedy!

Later, Gordon finds a present addressed to him on the sidewalk. Earlier, Ivy eradicated the Legion of Doom headquarters, putting Gordon, King Shark and the others out of work. Therefore, he has time to track down the person who attempted to murder Barbara.

Thankfully, Harley has a gift for Gordon, with a note that reads, “This knob goblin shot Batgirl,” with an adorable cartoon Harley sketched in the corner that looks like Dee Dee from Dexter’s Laboratory. We see Joker inside the package. Gordon can’t wait to employ torture methods from his favorite A24 horror movies. The joke comes full circle. 

Meanwhile, Superman, fully revitalized, repairs the Moon, which was in two halves. Our two girlfriends wait in the Gotham cemetery that evening. Ivy pretends to pay homage to Clegg at his gravesite, everyone’s favorite “indifferent husband.” Barbara arrives in a wheelchair after watching Harley and Ivy kiss. Barbara reveals she’s not staying with the Bat Family. She’d rather put her hacking talents to use elsewhere. In fact, she wants to do whatever Harley and Ivy decide to do.

Unexpectedly, Catwoman (Sanaa Lathan) emerges from the shadows. She wants to show them something she discovered while she was graverobbing. Before that, though, the quartet decides on a name for their new group. What about “Gotham City Sirens“? Maybe. “The Birds of Prey”? Well, none of them are birds, so that doesn’t work. The group eventually lands on the former. Eek! I love the direction this show is taking us.

While the Gotham City Sirens comprises Harley, Ivy and Catwoman, I’d love to have Barbara join their ranks. Perhaps their crimes can be environmentally and socially conscious, like Ivy wants, making Barbara’s involvement more realistic. 

Anyway, someone stole Nightwing’s corpse. Uh-oh. That can be the Gotham City Sirens’ first case — finding the city’s best (And dead?) ass. Well, about that… At the Lazarus Hot Springs, we see Talia with Damian. She informs him that his friend will look a bit different. Suddenly, Nightwing (Harvey Guillén) emerges from the hot springs, alive and well. Nightwing asks where Harley Quinn is. It’s revenge time.

Despite Season 4’s inconsistent tone, I thoroughly enjoyed some arcs, including Alfred spending the whole season trying to access Blackgate to spend time with Bruce, only for the latter to break free in the finale. Hilarious. I loved Bane’s Italian adventure and Harley and Ivy’s trip to the future. The last few episodes were definitely a return to form. Of course, the vocal performances are always on point regardless of whether the narrative beats land and the jokes never fail to elicit a chuckle from me. 

I need more Dr. Psycho, King Shark and Clayface in Season 5. I’m also excited to usher Bruce Wayne back into the story fold. Bring on all the cheeky chaos, dick jokes and Harlivy romance — please, and thank you.
