"Let me get this straight... so the core problem is the soul trait you were injected with?"
At Murder's words, Lust nodded.
"It's that... lust trait that turned our Underground into this mess."
"Then... have you tried extracting it?"
"No."
Lust shook his head.
"Actually, I was the first to realize how dangerous this trait was. I tried going to Alphys and Dr. Gaster to get them to help me find a way to deal with this thing injected into our souls."
"But they... had already been poisoned by that lust trait..."
Insanity nodded thoughtfully.
"Desire is the most primal instinct of every animal in the world. Once it grows strong enough, no one can resist it."
Insanity had been like that before. Her desire for the thrill of killing had dragged her deep into it. If she hadn't been given that second injection, she might still have been repeating the cycle of "reset - slaughter - reset."
"Right. I tried persuading them to research it with me and remove this thing that was ruining everyone. But they... couldn't live without that trait anymore."
Lust looked regretful, too.
"You can't imagine what it was like to see the brightest minds in the entire Underground come together just to discuss how to satisfy their lust."
"After that... I gave up. That feeling of... being the only sober one in a world of drunks... it was truly sickening to the bone."
Killer patted Lust on the shoulder.
"It's all right. We came here to help you!"
"No... how are you going to help? I've already given up. Anything we do... is meaningless."
Lust raised his head, his beautiful pink eyes holding nothing but emptiness.
"Have you ever tried... using a machine to extract the lust?"
Murder asked. He hadn't neglected science in Dusttale's spacetime, either. When the human wasn't around, he often researched related subjects.
To him, resets were a pile of dung with flowers stuck in it. The flowers were the ample time they gave him to carry out his research.
First, he had built an anti-reset field, then repaired the time machine. After that, he had begun researching his own determination.
Then came the overlapping timelines, and he met Killer.
Ultimately, he still had a solid grounding in science. Perhaps he could use what he already knew to create a bone-shocking miracle.
"I tried. But... it didn't work."
Lust rummaged inside his underwear and pulled out a small device.
"This thing... suppresses surging lust when I keep it on me. When I realized that desire was starting to destroy my sanity and torment my mind... I rushed to build this."
"I have to say... thanks to this little device, I didn't become as... depraved as they did."
Lust blinked.
"Unfortunately... this thing can't eliminate my lust completely, and I don't have enough materials to mass-produce it."
Suddenly, Murder pulled out a photograph.
"Lust, have you ever seen... this machine?"
The photograph in Murder's hand showed none other than the Determination Extractor from his world.
"Murder... you made fun of me for bringing rope last time... who takes a picture of this thing?"
Killer whispered to Murder.
"How is that the same thing...? I took a picture of it precisely to deal with unexpected situations like this..."
Murder pushed Killer's head away as she leaned closer.
