Oddly, Gwen was calm. Maybe it wad due to having dealt with the most insane killers of them all, having solved the most difficult cases. Whenever there was a case that needed a brilliant detective, Gwen was who they called. That's why this case was given to her.

Though, it did make sense. Skeletons had went extinct in their world, so it was rather curious to how four randomly popped up. And it explained what Sans had been talking about, and why Red had been upset he told. None of them were from this universe.

It also explained to why they all looked the same, to why all of their names were Sans. And why it said Papyrus loved all versions of Sans. This all made sense, it connected together. Why Sans said that wasn't his Papyrus.

The third and final Sans, the final suspect.

Even with the new information, entering the room still was shocking as ever. Not only did the unreasonably cold air hit her despite having turned up the heat, but the sight.

Why was there a collar on his neck?

The other two suspects had been wearing hoodies, so their necks had been hidden under the fluff. Not this skeleton. His neck was out for her to see, displaying a thick collar tightly encased around his neck with the bright word 'Papyrus' embedded on the brown material.

*Sans, also called Blue

*LV 1

*20 ATK 8 DEF

*A decent, honorable fighter

*Wished he had stood up to Papyrus sooner

"Hello, my name is detective Gwen, I'll be working on your case," Gwen had told him.

"Uh, I'm... I'm Blue," The skeleton said hesitantly, "That's what people call me."

"I am aware, yes."

She let her eyes collect in his appearance, green eyes wondering about. His wrists matched Red's own, markings from chains evident. She would definitely have to check Sans' wrists later, since he likely had those same markings.

"Is Sans alright?" Blue suddenly blurted out, cutting through the silence.

"What?" Gwen asked.

"When I was brought in here, the Officer was really rough, I just wanted to make sure Sans' foot was fine," Blue said, "I know it hurts when he walks on it. He needed help walking before."

"His foot?"

Gwen hadn't seen his foot, or even the lower half of his body. Whenever she entered the interrogation room, the suspects would always be sitting and waiting for her. Then she would always leave before they did, so she never watched them walk.

"His foot is injured, I was hoping if uh... you know, he was getting medical attention? Mweh..."

The 'mweh' he said sounded more like a throw away line to try and stay positive, not anything else. Blue clearly was trying to stay hopeful, even though he was in jail. And Blue was concerning himself for the health of his friend.

But they didn't give that type of care to people, not to murder suspects. That wasn't what the police did, not in her world.

"Don't worry about it-"

"Don't worry about it?" Blue snapped.

She had not expected that, Gwen snapping her head up from his file with surprise. When he had spoken softly, she had assumed he was a mushy pushover. Red had been surprised Sans was the one to out their origins of a different universe, he likely had assumed it was Blue.

"He's my friend, and he's injured! Of course I'm going to worry about it! It was my fault he hurt his foot, that he broke it!" Blue said, tapping his chest.

Gwen followed his hand, noticing the odd way he had tapped his chest. His hand looked bent to the side, and his movements looked pained, slowed. Not broken, maybe twisted funny. It likely only stung, really, which was why Blue was ignoring it. The wound didn't even look new, it looked to be a day old.

"How exactly is it your fault?" Gwen asked.

Blue fell silent, leaving her to sigh. Just when she got a few more answers, a new question would always replace an old one.

"So, you were kidnapped by Papyrus with the two other Sanses, Red and Sans, correct?" Gwen asked.

"Yes," Blue answered honestly.

"Did you kill Papyrus Font?"

There was a moment of hesitation before Blue answered. "No, I didn't."

So all of them were pleading innocent. Frankly, she had expected that. Why would a murderer plead guilty? They were a sinner, and sinners constantly lied and deceived others. That's what Gwen was for, to weed out the sinners and send them to where they belonged.

But now there was a doubt, a tiny whisper, in the back of her mind. Her gut coiled with that whisper, agreeing to bring it to the light of her conscious thoughts.

They weren't from her world. They weren't born here, raised here. They were born in different worlds, with different rules and people. Did Gwen have any right to even question them, to judge them?

No, no. Sinners were born sinners, killers were born killers. Red would be sent to his death for murder from his universe, and whoever killed Papyrus would be following. Unless Red was the one to kill Papyrus, then it would be only him.

"I know that you're from a different universe, as were the other two in your group, and I'm assuming Papyrus too," Gwen said, "Is that right?"

"Yeah," Blue said, nodding softly. "Sorry about the cold air, I know it's cold in whatever room we're in. It's because we're from another universe, and since we don't belong here, the air gets colder. Someone had explained it to me before, but I was sort of distracted at the time. Sorry."

Oh, so that was the cause of the cold air? Gwen would admit it was colder than normal, and she had checked the heater before entering, making darn sure it would be warm this time. She made a note to herself to ask Cooper about it later, writing it down. She didn't understand how that worked, but then again, she didn't even understand the weird machine when Cooper had explained it to her. Maybe he would understand this.

"No, no, it's fine," Gwen said, "But why do you guys call yourself that? Like Blue and Red, but Sans is still called Sans. You all are named Sans, right?"

"Yeah, I'm Sans, and so are the others," Blue said, "But you know, it gets really confusing when we're all named Sans, so we decided to give some of us nicknames. Sans got to be Sans because he was there first, Red became Red because of his sweater and I got Blue because of my bandanna, which I don't have anymore."

"What happened to your bandanna?" Gwen asked.

"Papyrus had taken it away, I was the only one who wore a bandanna. He said it got in the way of his collar."

The skeleton thumbed at the leather object, gently pulling at it with disdain for the symbol it created.

The skeleton had kidnapped three of the same person from different universes, had marked them with collars, chained them to a wall, and his check had said he loved all versions of Sans very, very much.

That was pretty concerning.

"He was obsessed with you, wasn't he?" Gwen asked, "That's why he went to different universes, to get multiple Sanses?"

Blue nodded, giving her a small glance. "He said he loved us. I believed it at first, I really did. I thought he was just showing his love wrong."

"But what happened?"

His gaze was serious as he looked up at her, yanking at the collar with a firm tug. "That wasn't love. It was obsession."
