Simon & Marcy

Synopsis
Ice King and Marceline 996 years ago.

Plot
The episode opens with Marceline, Finn, Jake, and the Ice King playing basketball at Marceline's house. Finn and Jake question Marceline on why she invited the Ice King, and she explains to them about her long history with the Ice King/Simon. The two request her to tell them about their past, as the Ice King comes back from getting water, agreeing.

She begins telling a story about the two of them (exactly) 996 years ago. It starts with Simon and Marcy wandering through the empty ruins of human civilization, destroyed in the Great Mushroom War, searching for food. At the edge of the forest, they find a mail box but there is only a dead rat inside. Simon tries to keep Marcy's spirits up by joking around, remarking that the rat will be a cute new traveling partner. He discovers a VHS tape nearby on the ground, and suggests they "watch" it - without a VHS player or electricity, he literally stares at the tape, then jokes that it was a boring movie. They then hear a rustle from the woods, and Simon puts his crown on to protect them, even though Marcy is clearly afraid of what the crown does to him. Simon reassures her and says he has to to keep her safe. Once Simon put the crown on his head, its magic makes Simon forget himself. Marcy begs Simon to take off the crown. Simon mistakenly calls Marcy "Gunter" and tells her to play in the snow as he generates snowflakes to cover her. Simon has no control of himself as he blasts the deer with ice anyway. Marcy throws a snowball to knock Simon's crown off. It takes a little while for the effects from the crown to wear off, and this worries Marcy. She then makes Simon promise never to put it on again. Marcy doesn't know what the animal is, and Simon explains that it is a deer. Marcy wonders that if the deer was alive in the woods, maybe other things have survived the war out there as well. Simon pauses and ponders the question, but honestly doesn't know.

At the end of the day, Simon sets up camp for the two of them. The deer he froze in ice has solved their food problem for the moment, and Simon cooks it over their campfire. He tries to make her laugh by acting out an episode of "Cheers" for her through a broken television. Marceline has a good laugh, but then begins to cough, making Simon realize she has a low fever. He tells her to sleep to preserve her strength.

Simon decides that Marcy needs chicken soup, and remembers that he saw a "Soupery" shop in a town they recently passed. Not wanting Marcy to walk all that way, he finds an abandoned motorcycle, but loses control when he tries to ride it, and they bail out before it crashes into a wall. Still not wanting Marcy to walk all the way, she rides on a wheeled chair that he pushes all the way into town. He sings and human beatboxes along the way to cheer up Marcy. Simon breaks a window to get into the soup shop, though he warns Marcy that vandalism is wrong. Unfortunately, the shelves of the soup shop are all empty (except for some soup-themed novelty gift cards). Just then, Marcy looks in the security mirror in the end of the aisle, and notices...something, shambling along in the next aisle. Simon peers over the shelves and is shocked to see some sort of weird mutant slime-creature. Alerted to their presence, it advances towards them, but Simon knocks the creature out by smashing its face in with his crown, and they flee.

Later, Simon and Marcy quest deeper into an abandoned city, by walking through a large concrete storm-drain. Marcy seems worse, but Simon notices a food truck abandoned on a broken bridge that passes over the storm-drain up ahead. They climb up, only to see it's a clam truck called, "The Clambulance". A frustrated Simon asks Marcy to cover her ears as he "curses" and kicks the truck. Suddenly, slime creatures emerge from inside. Simon then pushes the truck off of the bridge with the slime creatures on it, but the the truck's siren starts going off after it crashes into the ground. This attracts an army of the slime creatures, who chase Simon and Marcy to a dead end in an alleyway. Simon is forced to put his crown on, and tries to stay normal by singing Gary Portnoy's "Where Everybody Knows Your Name" (the theme from "Cheers") repeatedly, and after knocking all of the creatures out, takes his crown off. However, this time, most effects of the crown don't go away (his beard is the only thing that shrinks back to its normal length). Chicken soup and a can opener then fall from a large wad of bubblegum clinging to the side of a building. Upon closer inspection, it appears to have a face, which smiles at Simon. He then uses the soup to cure Marcy. Marcy tells Simon she loves him and hugs him. Simon then says "I love you too...Gunter."

The episode then goes back to the present. Marceline finishes the story, by saying that she gets better, and she and Simon live happily ever after (which makes the Ice King feel happy). He then tells her to keep telling "these chumps" stories while he scores more baskets, proving he has no recollection of the events himself. The episode ends with Marceline, Finn, and Jake smiling at the Ice King being happy.

 * Marceline does not have a bite mark, cannot fly, and can withstand exposure to the sun.
 * Simon calls Marceline "Gunter" with the crown on. Later, toward the end of the flashback, he does this again without the crown on. This shows that Simon has fallen deeper into his transformation into the Ice King.
 * The mutagenic effects of the Mushroom Bomb/Mushroom War can be seen when creatures oozing green slime from open pores throughout their bodies appear.
 * A pink gum substance is also seen attached to buildings and trees. Also at the episode’s end, a chicken soup can and Swiss army knife with a spoon is brought down by a pink gum-like substance attached to a building. A face begins to form in the gum, startling Simon.
 * The Chinese characters 水 ("water") and 人生 ("human life") appear on a bottle inside the first car Marcy hides in. In addition to this, in the upper-right-hand corner of the broken television, the Japanese characters such as テレビ ("television") can be found.
 * Simon has drumsticks in his backpack hinting that he already knew how to play the drums.
 * By the Clambulance when Simon looks down to find a radiated creature below the truck, the registration plate of the truck says "CLAM 1" "The Wut-Wut state."

Cultural references

 * Ice King sang the song "Where Everybody Knows Your Name," the theme song for the television show "Cheers." He likewise calls out for Norm, a character on the show, and re-enacts an episode.
 * After singing the Cheers theme song the first time, Simon said "Filmed before a live studio audience," a quote commonly used by announcers of live television shows.

Episode connections

 * Ice King and Marceline were revealed to have known each other from hundreds of years ago in "I Remember You."
 * This episode was first aired as a two-part special with the previous episode, "I Remember You," similar to "Bad Little Boy's" original airing with "Fionna and Cake."
 * Simon calling young Marceline "Gunter" may be the reason why Marceline has "Gunter" on the cover of her journal in the episode "Marceline's Closet."
 * The grape soda can that Simon finds bears a striking resemblance to the one Jake uses to feed the Princess plant in Death in Bloom.

Errors

 * During the first airing of this episode, the title card was never shown.
 * When Simon was going to hit the monster with his crown, he was holding it backwards but when he hits it, he is holding it forward.
 * The drumstick in Simon's backpack with tape on it switches sides when Simon is talking to Marceline about wanting to carry her.

Production notes

 * This is the final episode that Rebecca Sugar worked on before she left to create .
 * This is the seventh episode to be leaked online before its intended air date, after "Fionna and Cake," "Hot to the Touch," "Finn the Human," "Jake the Dog," "Up a Tree," and "Bad Little Boy."

Storyline analysis
According to the show, Simon is slowly changing into the Ice King, because the effects of the Crown take longer and longer to wear off after every interaction with it. Marcy is not a full fledged vampire, just a half demon. Also, there are millions of mutant slime creatures that are everywhere, and a face in a wad of pink bubblegum. What do all of these things have in common? The Great Mushroom War! If I am correct, the cause of the extintion of the human life on Earth as we know it was because of the Great Mushroom War. Because of the large amounts of slime creatures, and no dead bodies on the ground, then logic dictates they must have mutated in to the Slime creatures. the mutation could have occured because of an explosion of the Bombs much like the one showed in Finn the Human, and the people that were close to it, were affected. I state this because the same green goo that the Lich uses in the first two episodes he appeares in, and the liquid in the crater that was the cause of a huge explosion that created a mushroom cloud in the episode of Adventure time, Jake the Dog, was oozing out of the creatures in this episode. Also, in the wad of gum, that resembles Princess Bubblegum's hair color, there was a face, (probably another mutated person). This could explain the creation of the candy people, and the Candy Kingdom itself! The only two things I can't explain are Marcy and Simon's conditions. Simon said in the Adventure time Christmas special (in a recording) that he found the Crown in Scandinavia (which probably ended up becoming the Ice Kingdom). And Marcy is not a Vampire as a kid, but is as an adult. There is no given evidence to answer these quesations just yet, but i am very sertain they have to do with the War. We won't know until the next episode of Adventure time, but until then, we are this much closer to figuring out Adventure time's vast and very confusing backstory.
