Harley Quinn ended the first season of the animated series with the title character, Harley Quinn (Kaley Cuoco), seeking revenge on The Joker (Alan Tudyk) for killing Dr Pamela Isley / Poison Ivy (Lake Bell) in the previous episode.

Whilst a significant portion of Gotham was rescued to rubble, with it having been hit by an 8.6 earthquake, everyone’s favourite environmental activist is brought back to life through the renewing power of nature. A few of Harley’s tears might have helped.

Looking back over the previous twelve episodes, if you have been following The Joker’s reactions to Harley working with her own crew, it is clear there was no way he was going to allow her to rise above him in the supervillain world. His ego wouldn’t have been able to cope with a successful Harley Quinn roaming the streets of Gotham.

The Joker set forth a plan to take down Harley Quinn and her crew. By the end of the penultimate episode, we saw the Legion of Doom headquarters destroyed and replaced with The Joker’s new self-imaged tower.

Even though the tower belonged to The Joker, not that he would admit it, the idea for it popping up from the ground like a jack-in-a-box was originally Harley’s brainchild. Much of the Justice League, except for Bruce Wayne / Batman (Diedrich Bader), had been banished into a book by the vindictive Tsaritsa / Queen of Fables (Wanda Sykes).

With Harley needing help defeating The Joker, something we possibly wouldn’t expect, she approaches Batman. Batman isn’t initially interested in helping Harley take down The Joker. He would much rather see her locked up in Arkham. The plan, with both Batman and Harley’s crew captured, doesn’t go off without a hitch. Clayface (Alan Tudyk), having transformed into Batman so that the real Batman can get into the tower undetected, isn’t able to resist hamming his performance.

Even though it ultimately fell to Harley to achieve the impossible, given how there are always unexpected twists in comic book adaptations, we shouldn’t be surprised with Ivy’s resurrection playing a key role in The Joker’s defeat. Also, not without great risk to himself, Batman saved both Harley and Ivy.

Was the earthquake caused by Ivy’s resurrection or was it The Joker destroying his own tower?
