Last time

Everything goes to hell as Flowey shoots a pellet through Red's chest. Roaring in pain, Red falls into a 'boneless' heap on the balcony.

And now
At the castle

Seeing Flowey prepare a whole row of 'pellets', Sans musters his still recovering magic and shoots a bone at the plant-monster. The bone hits, sending Flowey flying back into the abyss below. Turning to Red, Sans tries to focus any healing magic he can into healing him, noting how Red's breathing had become shallow in those few seconds. "Red, c'mon wake up. Please don't do this to me!" Sans shouts in desperation as he pumps green healing magic into him.

The others come as to rush in, but stay just out of sight, shocked. "Sans? Y-you came back?" Red asks in a relieved, but whispery tone. "Of course I did, silly. I couldn't let those....this is all my fault. I wish I had gotten here sooner" Sans laments, leaning his skull on Red's shoulder. Sans' smaller frame shudders and quakes as his tears flow down his skull in glowing rivulets.

"Maybe it's better this way" Red mutters dejectedly, looking off towards the edge of the balcony and away from Sans. Sans grabs Red's 'chin' and turns Red's face to look back at him again. "No. Please don't talk like that. Everything is gonna be alright. We're together now. It'll get better, you'll see" Sans encouraged to his downed lover.

"At least......I got to see you.....one......last......time....." Red mutters, bringing a clawed hand up to Sans' face, gently caressing his cheek. He holds his clawed hand there for a minute, before it drops to his side. Red's head falls back, eye lights fizzing out of existence as he loses consciousness.
Doing a quick check, Sans clutches his phalanges to his 'mouth' in shock. "No, no no no. Please, no. Please don't die on me" He murmurs as he completes the check.

Red
Lv: 10
HP: 0.9 – 0.6 – 0.3.............
He loves you deeply. Please don't mourn me, Sans. I love you.

"No, no no no! Please, please don't leave me!" Sans shouts into Red's still chest. "I love you" he murmurs as Red's body begins to become fuzzy at the edges. From where they are watching at the rose; Alph, Undyne, Toriel watch as the last petal falls off the sadly smiling face. They huddle together crying as they watch their master's body slowly begin to turn to dust.

As Sans lays on Red crying glowing blue tears, a beam of light falls, like a shooting star. Then another and another. Soon, Sans notices the beams of lights. He manages to stop crying for a minute, and then backs away from Red's body as the beams of light intensify in frequency.

A magical fog slowly envelopes Red, lifting the large being as if he were made of paper. The fog begins to emit a bright light which envelopes Red in its glow. Becoming wrapped in his cloak, Sans sees that Red's body is shifting. It's becoming smaller and less bulky. Claws become sharpened phalanges, hind paws become skeletal feet. Red shrinks and reshapes into a skeleton like Sans with the exception of the sharp teeth, one being gold.

Gradually, the magic that lifted Red's formerly large frame lowered the monster down with the same gentleness as before. Red stands, opening his stunning ruby colored eye lights, which smolders with a deep burning flame. Sans gives the now-much smaller monster a once over, noting the changes and differences from the being he came to know during his stay in the castle.

Giving Red a mysterious look, Sans cautiously moves forward until he is within arm's reach of him. "Heya, Sans. It's me, Red." The now same-heighted skeleton addresses Sans. Sans continues to stare, then, realizing that it is still the same Red, he lunges and they both crash onto the floor in a pile of bones.

Both glowing their own colored blushes; the two lovers press their teeth together in a kiss. Fireworks explode around them as the castle undergoes a transformation itself. The gloom surrounding the castle disappears like a winter storm, blowing away with the wind and revealing a blue sky.

The gargoyles change into cherubs, damages and destroyed portions of the castle seemingly fixing itself. Soon, everything is restored to its former glory. Sparkling lights envelope the castle inhabitants, who had been turned into objects. Undyne goes from a candlestick to a blue fish monster with bright red hair. Alph and Alphy's go from a clock and a featherduster to two slightly different colored orange scaled monsters. Toriel returns to being a goat monster. The footstool is a white fluffy dog and Frisk is a small child.

One by one, the inhabitants return to their former either human or monster conditions. Until all that is left is the red flower, without any petals. It glows and seemingly separate into two beings. One being a small goat monster whom Toriel refers to as Asriel and the other a armless orange monster child who Undyne affectionately suplexes, calling MK. The invisible barrier cutting the valley in which the castle and the village are in shimmers, as if slowly breaking down after a long time.

"Mom!" both Frisk and Asriel chorus, being embraced by Toriel. "This is awesome!" Undyne declares, whilst hugging the blushing Alphy's, who looks ready to swoon. "It's good to be back, huh, Undyne!" Alph, a darker orange version of Alphy's, says. The two could pass as twins. "Well, I did tell you he would break the spell didn't I?" Undyne boasts, putting Alphys down.

"No you did not, I believe I told you!" Alph shouts at her. "No you did not, you overgrown pocket watch!" Undyne shouts back, taking off her white glove and smacking the dark orange monster across the face. The two begin to squabble, not hearing the protests of Alphys, who wants them to stop and just get along for once. They scuffle past Toriel, Frisk and Asriel who are staring at the couple with soft smiles. "They sure make a cute couple, huh mom?" Frisk asks with a wink. Huffing at their siblings actions, Asriel nods. "Of course my children, they are going to be happy now." She tells her children.

"So this is Red, huh." Papp comments from where he and Paps are standing next to Toriel. "I won't have to sleep in the cupboard again will I mom?" Frisk asks Toriel, causing Papp and Paps to chuckle along with Toriel. "No my child" She answers, looking back at Sans and Red embracing, not caring about the others or that they are on the floor.

A week later, everyone is gathered in the ball room to celebrate after Red's and Sans' marriage. Red is waiting in the middle of the room, wearing his typical red formal wear. Coming into the room is a deeply blushing Sans, who is wearing the blue dress as before. Papp and Paps are in suits off to the side, glowing orange and red tears in their eyes at the happy moments that have occurred in the past week.

Once Sans makes it to Red, the two begin to dance around the room. After a few turns, the others join in, monster and human alike.

"Certain as the sun

Rising in the east

Tale as old as time, song as old as rhyme

Sans and the beast!"

"Tale as old as time, song as old as rhyme
Sans and the beast!" Toriel sings softly, watching the dancing and festivities from the edge of the room with her two children, Frisk and Asriel.

The next morning Red and Sans make their way to the seal where the barrier's original point of origin is. Clasping their hands together, the two gather their magic in them. Placing the clasped together hands to the seal, Sans and Red pour magic and love into the seal. With a loud shattering noise, the rest of the seal comes down. The magic that was holding it together evaporating back into the earth.

Returning to the castle, Red and Sans take some well-deserved time to themselves as Toriel, Undyne, Alph and Alphys help Papp and Paps with the politics of monster kind returning to the world.
