If you've heard of the show "Mixing AUs", then you know Paper Jam. She started dating Underfresh Sans in Season 2, Episode 5. Before Episode 5, though, there was an episode that had a much different plot than the final episode. The original episode's name is "Fresh Jam", and the episode before it was "Paper Jam's Suicide".
The first 5 minutes were of the first 5 minutes of "Fresh Jam". Instead of Underfresh Sans admitting that he loves Paper Jam back, he said 2 sentences. "I... really dunno what to say, pal. I hate to say this, but... I don't love you back." Paper Jam was saddened, but Fresh, in attempts of cheering her up, said, "Don't worry, there are more boys out there that might like you." The attempt failed, and it fades to Errortale Sans and Inktale Sans speaking to each other. They here a little girl's cry, and they run offscreen.
It cut to Paper Jam sitting on her bed, crying in the little girl's voice. Ink and Error walk in, and ask her what's wrong. She did not reply at all. They walk out. The screen cute to a normally cutesy title card reading, "A Few Hours Later". It shows Paper Jam at her desk with a paper and a pencil. She writes and narrates out loud.
Dear World,
Underfresh Sans was the only one I really loved, but he doesn't love me back. I tried asking other boys out, but they all denied me. I guess it's time to end it, once and for all! Well, goodbye, cruel world.
Love,
Paper Jam
She got out a gun, and put it in her mouth. The screen cuts to Ink, lying his head on Error's lap. Suddenly, a loud gunshot was heard. Ink's head jolted up, and he and Error jumped up and ran into Paper Jam's room. They found her lying on the floor, with black ink (acting as blood) and brain matter everywhere. The episode then ends.
