Logline
On Halloween, Artemis and Zatanna go to Manhattan for a night on the town, only to be hunted by Harm, a psycho-in-training, hiding a deadly secret...

Continuity

 * Kid Flash still has his cast still after he injured his arm in "Revelation" while fighting against the Injustice League.
 * According to Red Arrow, Miss Martian stowed away on Martian Manhunter's ship around June. This casts doubt on the origin story she told in Young Justice #6.
 * Artemis's romantic feelings towards Superboy are brought up once again.
 * Zatanna mentions a move she had practiced after fighting with the Reds in "Humanity".

Trivia

 * The costume that Karen Beecher wears is similar to her comics persona Bumblebee.
 * The costume that Mal Duncan wears is similar to the original costume Superboy wore in the comics.
 * The sheath of Harm's sword is the arm of Grendel from Beowulf.
 * A student at the Halloween Dance was dressed as The Flaming C.
 * Abel's House of Secrets is a reference to the House of Secrets, a mansion that played a large role in mystical and magical stories since the 70s. Abel is the biblical Abel, son of Adam and Eve, who served as the host.

Goofs

 * The NYPD police cars are incorrectly colored black and white instead of white with blue markings.
 * If Secret was indeed a ghost, and also intangible, how did she remove Zatana's gag?

Cultural references

 * When Megan comes out as a Martian to trick Marvin she looks like Marvin the Martian from Looney Tunes.
