Harley Quinn Season 4 Reveals Nightwing's Killer - And It's Disastrous

Season 4 of Harley Quinn has revealed the identity of Nightwing's murderer, and it's going to change the series in a massive way.

A major mystery in Season 4 of Harley Quinn has been who killed Nightwing. Admittedly, the death initially felt like a joke, but it turns out that Dick Grayson was indeed murdered. Unfortunately, Harley and Batgirl had no clue who did it, as they weren't really feuding with anyone at the time.

The timing was absolutely abysmal as well, with Bruce, as a wealthy elite, tossed in jail, offering no leadership or detective to help solve the case. Not to mention, Talia al Ghul stymied the Bat-Family's finances, which left Batgirl angry and seeking revenge. Well, the bombshell behind the death has finally been dropped. And make no mistake, it's going to test what's left of Harley's inner circle in a big way.

Harley Quinn Season 4 Confirms Harley Killed Nightwing

Harley's been racking her brain trying to figure out who murdered Nightwing and left him in the snowy mountains outside Gotham. Even a trip to the future didn't help. Harley only managed to meet a dark spin on Batman #666, realizing the past needs fixing ASAP. However, the truth unfolds when she gets back home and becomes ensconced in her own clone saga.

Harley's been sleepwalking all season long. Plus, she's hallucinating an evil double. Well, the double actually exists, and this copy isn't evil. In fact, she's been helping clean up crime, coming off more heroic than Harley. As fate would have it, Jim Gordon accidentally cloned Harley from a hair when heating up a potato in a microwave/clone machine at the Legion of Doom HQ. Yeah, it's weird and totally out of left field, but that's the very essence of this series.

That drama aside, the clone confesses she was at the cabin when Harley went to find Barbara that night. A hateful Dick emerged, thinking Harley kidnapped Barbara, not realizing Harley was sleepwalking. Adamant she could be a hero, Harley strangled Nightwing with the friendship bracelet he refused and then planted the body in a tree. Harley 2.0, who opted to stay in the shadows after being "born," saw it all. She kept it mum all this time because she knew it was accidental. After the body dropped and Batgirl was left distraught, Harley 2.0 decided to help redeem the original by doing more heroic deeds.

Harley Quinn Season 4 Finds Harley Breaking More Rules

Harley ends up using Doctor Psycho to probe her memories and see that this all did happen. However, knowing he'd be problematic with the secret, she knocks him out and has Flash come over with the Cosmic Treadmill. Harley then goes back in time, avoids the session with Psycho and ignores the fact she could give Harley Quinn another Flashpoint.

Again, it seems Harley, much like the show, has no grasp on the idea of consequences, time-meddling and messing with people's brains. It's part and parcel of why fans aren't sure if she really has what it takes to be a hero. Ironically, this is the position Dick took, which is why he constantly berated Harley. He felt she was a mocking pretender, only for his rage to be met with punishment. Still, while it's understandable what Harley has been doing to cover her tracks, she's proving Dick right.

She just doesn't understand ownership of the situation. There's no accountability, transparency and sense of responsibility. It makes Harley a tad hypocritical because these are things she's asked of Poison Ivy. Sure, they've reconciled after meeting their daughter, Neytiri, in the broken future, but Harley has called out Ivy for being in the toxic Legion of Doom and not embracing her duties as a lover. In Harley's case, she's avoiding hers as a superhero, seeking to hide a truth that would definitely ruin her reputation.

Harley Quinn Season 4 Could Break Harley for Good

The episode ends with Harley killing her clone and lying to Barbara. She tells Batgirl she didn't commit the murder -- the clone did. While Barbara does get attacked by Joker at the end, one has to wonder what'll happen if everyone learns the truth. Bruce will be annoyed; a jailed Alfred won't like that Harley's lying, and there's the possibility the show embraces Damian's potential as Dark Robin if he decides Harley has to pay.

The Barbara blow will hurt the most, though. Barbara considers Harley a sister, and while Batgirl has anger issues, she sees Harley as a true north. She's always believed in Harley, leaving fans wondering if she recovers, what'll be her stance. All these lies and guilt do seem destined to snowball and affect Harley mentally. Her sleepwalking and fractured psyche could kick into overdrive, leading her to more dastardly acts. Clearly, she's at a major crossroads, but as vulnerable as she is, she has to come clean.

Harley needs to exorcise these demons permanently if she's to move forward -- not as a hero but as a person. Luckily, she does have one bedrock in Ivy. But Ivy could get caught up with her mentees, the Natural Disasters, and her Legion of Doom job now that Lex is out. Ivy's not been that supportive of a partner this season, so with more power, she can become more corrupt. Sadly, now's not the time to be ignoring Harley. She needs help and a shoulder to lean on, so hopefully, Ivy puts her soulmate and true love first. Harley's mind and body are at stake, as well as the notion that Gotham could turn on her if word emerges about what she did. Throw in the Bat-Family potentially being at her throat, and it does feel like Harley Quinn Season 4 is inching a step closer to breaking Harley for good in its finale.
