The following one shot is centred around the song Partners in Crime.

"You'll never take us alive," Elsa shouted before the two of them vanished.

Guards frantically searched for the criminals but couldn't find a trace. Meanwhile, Elsa and her partner Hiccup were leaving the island on a nearby boat, with the captain's hands tied to the steering wheel. 

"We leave for Corona, cutie," Hiccup said, grabbing Elsa's waist and snuggling his nose into her neck. She giggled.

"They will one day call our crimes a work of art, won't they?" She asked, looking into the horizon.

"We will always lived as spoiled royalty, lovers and partners. Partners in crime," he said, hugging her from behind.

The next day, the two lovers docked at Corona and used disguises to get in the castle. The princess, Rapunzel was having her coronation and they had decided to crash it, Hiccelsa style. As the to-be-queen picked up the orb, Hiccup stood up, got his gun out and yelled

"Everybody freeze!" 

Elsa copied, only yelling

"Nobody move!"

Everyone in the crowd was startled. The priest's eyes were more like golfballs. Rapunzel and her fiancè, Eugene, both had fear in their eyes. Hiccup slowly moved towards the princess, grabbing her in a headlock. Eugene immediatly tried to get her back but was knocked out by Elsa. Still struggling with Rapunzel, Hiccup nodded to Elsa and the two of them fired at a glass-stained window, resulting in a crash.

"Now if you will excuse us, ladies and gentlemen, me and my doll will be on our way," the brown-haired boy said, before the bonde, platinum blonde and himself disappeared.

The crowd immediatly started to chatter.

"They're paper faces flood the streets," one said in fright.

The couple made the way to 'their boat' and begun to set sail. They headed downstairs to the living quarters and put Rapunzel in chains.

"She doesn't seem like a princess anymore, let alone a queen," Elsa snickered, as the two of them left the room.

 "Where to next?"

"Arendelle, thought your sister might want a visit," Hiccup chuckled.

"You still swear that death will do us part?" The girl asked.

 He nodded. The next day, they threw Rapunzel overboard before docking at Arendelle. Everyone bowed at their presence, with Elsa being the former queen of the land. The two arrived at the castle,  went inside and made their way to the throne room. Sitting on the thrones were Elsa's sister, Queen Anna and her husband, King Kristoff. 

"My dear sister, I have an anouncement that I want to make in your presence," Anna said, cheerily. Then she went all serious. "I won't go down without a fight."

Immediatly, the hall was filled with guards, surrounding Hiccup and Elsa.

"They've got us pinned," Hiccup whispered.

"Baby, I'm a little scared," Elsa whispered back. 

He took her hand.

"Don't quit," the boy spoke, softly.

They both took out their guns and started to attack, killing many guards. Many fought off but still ended up as their mates did. 

"Put your weapons down," the leader said. 

Neither of them did.

"Ready men. Aim? Fire!" He shouted. 

Two crossbows hit Hiccup and Elsa's back. Both of them fell to the ground. With all the strength she had left, the platinum blonde takes out a recording of a pocket and presses play.

The skies are black with lead filled rain

A morbid painting on display

This is the night the young love die

Buried at each other's side

You never took us alive

We swore that death will do us part

So now we haunt you in the dark

You never took us alive

We live as ghosts among these streets

Lovers and partners

Partners in crime

The End
