Warning: SPOILERS for Chucky season 1, episode 4.

Chucky episode 4, "Just Let Go" saw several of the show's storylines come to a head but didn't forget to pack in several Child's Play Easter eggs and movie references too. By bringing the iconic killer doll to the television, creator Don Mancini gave himself a lot more room for nods to the past and homages to other works. In that regard, the Chucky TV show has elevated its rewatchability factor, with Chucky episode 2 alone full of Easter eggs to everything from Heathers to Hello Kitty. Mancini himself even made a cameo.

Things heated up, literally and figuratively, in Chucky episode 3, "I Like to Be Hugged" as Jake Wheeler (Zackary Arthur) gave in to his anger and pain. As he did so, the nods also increased in equal measure and several lines from past Child's Play movies were reused. Lexy Cross (Alyvia Alyn Lind) sang "(Don't Fear) The Reaper" by Blue Oyster Cult, a staple of many horror movie soundtracks. All of these served to reward attentive longtime Chucky fans.

Chucky episode 4 picked up in the dramatic aftermath of Chucky episode 3 and its many references. Despite that, the Chucky TV show writers refused to slow down. Here's a breakdown of every reference and nod to be found in Chucky episode 4, "Just Let Go."

Eddie Caputo

Young Eddie Caputo in Chucky Episode 4

Delving once more into Charles Lee Ray's past, Chucky episode 4 explored his early teenage years at a boy's home. There he made his first "friend to the end." The younger boy was revealed to be Eddie Caputo, who featured in the original Child's Play movie, and would go on to become an accomplice of Charles' who ultimately abandoned the killer and was vengefully murdered by him. As such, his "cross my heart and hope to die" line is tragic foreshadowing.

Halloween 2

Previously, Chucky episode 2 referenced Halloween 2's razor blade scene for one of its darker Easter eggs. That particular well was revisited in Chucky episode 4. With much of the action set in Hackensack Memorial Hospital, it loomed as eerily empty as Haddonfield's facility.

"Ugly Doll"

As a detective collected Chucky, he remarked that he was "a f***ing ugly doll." Chucky was similarly insulted by an elderly lady in the original Child's Play. Where she only received a verbal rebuttal, the officer met a much more brutal fate.

The Shining

As Jake waited for news at the hospital, a ball rolled down the corridor to him. Though the source proved not quite so sinister, the moment echoed a scene from The Shining. There, Danny was lured into Room 237 when a ball rolled ominously over to him.

Peter Pan

During Chucky episode 4's flashbacks, the teenage Charles could be seen reading and playing twisted games based on Peter Pan. As well as informing why Chucky wants to remain a doll, it also explained elements of his wider M.O., especially regarding child proteges.

"You Might Feel A Little Prick!"

Brad Dourif as Burned Chucky in Chucky Episode 4

Chucky offered this sardonic one-liner before stabbing the aforementioned detective with a dagger of needles. This was paraphrased from Cult of Chucky, which saw him equally terrorize a medical facility. The tagline for that sequel read: "You may feel a little prick."

Good Guy Merchandise

Kid in Good Guy Overalls in Chucky Episode 4

Potentially a two-for-one, a mother and child flitted around Chucky episode 4 without connection to the story. As a result, they shared similarities with the mother and razor-afflicted child glimpsed during Halloween 2. The child also wore Good Guy merchandise not dissimilar from those worn in the original Child's Play by Andy Barclay.

North By Northwest

Cary Grant as Roger Thornhill and Eva Marie Saint as Eve Kendall in North By Northwest

After Lexy fell into another life or death situation in Chucky episode 4, Jake finally turned from the dark side and chose to save rather than kill her. The whole moment, from when he caught Lexy to when he pulled her to safety, homages the climactic Mount Rushmore scenes from Alfred Hitchcock's North By Northwest.

Chucky's Trademark

Brad Dourif as Chucky Burnt in Chucky Episode 4

Chucky episode 4's own climactic moment saw the killer doll give Jake, Lexy, and Devon his middle finger. The move has long been a staple of Chucky's, offered up to several enemies over the decades. Last delivered to Nica in Cult of Chucky, it now solidified the end of his and Jake's friendship. Equally, it marked Jake, Lexy, and Devon as the official heroes of Chucky as they unite to stop him.
