Sans is a MONSTER and not a HUMAN, so he doesn't follow HUMAN biology like a HUMAN skeleton. Same with Gaster and Papyrus.  

-------------------------------

Of course, he just had to escape. Of all people, this was the person that had to escape from prison, and was someone that Frisk was expected to track down and deal with. She would never forget the day when she had been put on a mission to arrest the murderers of her parents, and how she had killed one of those men with her own hands. At first, she had regretted what she had done. She had dreaded taking away his life, even though he had hurt her so badly by stealing her parents away. Now, it wasn't something that haunted her at all. Because he was scum. Just like the second guy who they had managed to arrest, and was now on the run. And what was even more annoying was that he had to create a big scene.

It couldn't be like any other time when she had managed to take care of someone in secret, and it would be done and dusted with. Oh no, of course not. This time, she found herself hurtling down a busy street, having to shove by people going the opposite way as her target was trying to escape. There was no way that she could take him down in a place that was full of people, even if it was recognisable that the guy was clearly an escaped prisoner, as his face would have been plastered everywhere. She couldn't be seen pulling out a gun and shooting him in the back of the head. She somehow had to chase him to an area away from the public eye.

"Sorry, excuse me." Frisk apologised to people, who she had to shove past to continue running. She saw the man turn a corner, going into yet another populated area in which there seemed to be some kind of festival going on, which all kinds of stalls and events going on. And a lot of people. Frisk exhaled in frustration, wishing this bastard could stop being so difficult, as he went to pull a stall over to put it in her path. But she simply managed to jump over the newfound obstacle as she continued running after him. There was a stall upfront that appeared to be selling all kinds of different food, so he had used that to smack over onto the ground to try and slip her up. Again, using that tactic wasn't enough to slow her down. 

She had trained a lot for moments like this, and she wasn't going to let him get away! It was crazy to think that she had once been a girl who was pretty afraid of conflict, who was afraid of hurting others and getting herself hurt. She had come a long way since then, as she was chasing him up a fire escape to another building. Her lungs honestly felt like they were on fire at this point, but even so she was still trying to push herself. She had to keep going on, as she didn't want to let this man go, knowing he might hurt someone else. "For fuck sake... Just give it up already!" Frisk yelled after him, as even when they got to the roof, he was still running. 

"Fuck you!" He yelled back, and that's when Frisk growled and began the chase once more, following him across the roofs of various buildings, at least until it got to the point where the next building was way too far of a jump to go, and he had cornered himself. There was no way out apart from downwards, and it was a pretty long drop. "Shit." He hissed, only to turn around and see Frisk, glaring at him from where he was standing. He smirked. "Well, guess this is the end of the road for one of us." He said, going to pull out a knife. "How about you go back to your boss like this never happened, unless you want to meet your parents in heaven?" 

"Shut your mouth. You don't scare me." Frisk glared daggers at this man who thought that he could faze her, that she would just scuttle away in terror. She had done that when her parents had been murdered. All she did was hide away in the closet like they told her to, and she did nothing as she heard their screams of agony, and saw their bodies fall to the floor through the little vent in the closet door. She had been a coward and let her parents die, but now she could only make them proud by sending the second killer to hell. Prison was too good for him. 

"Well, that's a shame. I'll finally do what I intended to do a long fucking time ago then." With that being said, he made the first move, choosing to run at her with the knife. He was taller than her, but she doubted he was quicker. She thought the best plan of attack would be to knock his feet from out under him, so that he went tumbling over. She could even try to dodge the knife strike, to disarm him. Okay... 

As he tried to slash at her with his knife, she quickly brought one of her arms up to hold his arm back, so that the knife didn't even reach her. She pushed that arm away and went to bring one of her fists forward, to punch him across the face. In shock, he stumbled back, and she didn't even waste a moment to get her foot behind one of his, so that he fell over onto the ground. "Let go of the fucking knife!" She yelled at him, as she stomped on his wrist to try and get him to let go of the blade. He had let out a grunt of pain, but to her dismay, he managed to lift his arm that her foot tried to hold down, so she simply quickly stepped back, as he had the strength to pick himself up again even when she tried to hold him down, and he still had that blade. 

What was extremely inconvenient was that she didn't have a gun on her with a silencer, because if she could, she so would have taken the shot right about now for the center of his forehead. He smirked, while she continued to glare back at him. Did he think that after a single failed attempt of trying to take him down would cause her to feel scared? Because she wasn't afraid. "You're still just a silly little girl, trying to be what she isn't. Do me a favour and just say hello to your parents already." He spat, once again trying to slash at her with the knife. 

Dodging his attack, she went to grab for his wrist, wanting to try and twist it behind his back and kick him in one of the back of the knees - using the same tactic she had once used on Sans. But he didn't go down as easily, probably because unlike Sans, he wouldn't hold back whatsoever. Her boyfriend-- or rather, fiance, would never be able to give her his full potential at fighting, even if he tried to. That's when the man cackled, and he used the same tactic that Sans had with her, where he pushed all his weight back into her.

To her horror, she was standing right at the edge of the roof, and she felt her foot go off the edge. She was so sure she was going to fall, but instead, the man kept a firm hold of her wrist, and allowed her to dangle off the edge for a second. She was questioning why he didn't just let her fall to her death, but it didn't take her very long to realise why, when she saw the long smirk across his lips, and the blade still within his hand. Just allowing her to fall and die wasn't satisfying enough to him. Frisk growled, trying to struggle as he pulled her back onto the roof, only to find herself pinned down. How the fuck was he so strong?! 

Okay... She said she wasn't scared before. Now she was absolutely shitting it. Especially when she saw that evil smile from the man above her, as he held his knife high up into the air above her, ready to strike. Was she actually going to die right now? No! She couldn't! She kept trying to struggle, as she thought about how she had to get back to Luna and Leo, to Sans! She couldn't just die after having only just proposed to him, there was no way! That was all she could think, at least until she could only think of something else.

Hot searing pain, all throughout her stomach. She let out an agonising scream, which likely would have been heard by so many people walking the streets below. She never knew of such agony, and it only got worse when she felt the metal being pulled away from her flesh, only to be stabbed in another location. Again, she could only scream and cry, once again being that vulnerable, helpless girl who she thought she had left far behind. But it appeared that that girl was still a part of her, as all she was mentally hoping was that someone would rescue her right now. She wished Sans was here with her right now. 

Right now, she could just imagine him, coming along to take this man down, and saving her life. But he wasn't here right now. He didn't even know she was in danger, because he had to trust that she could protect herself. And most of the time, she could. But right now, was not one of those times where she was capable. One of those times was the moment where she was so sure she was going to lose her life. She didn't want to die. She wasn't anywhere near ready to die. But she was sure that was going to be her fate, at least until... 

The man let out a grunt of pain as a bullet appeared to fly through the air, hitting him in the shoulder. There hadn't been any sound of a gunshot, which meant the shooter probably had some kind of silencer. It was then that Frisk saw the man get up, getting up off of her, and he appeared to be making a run for it. After that, she wasn't quite sure what was happening, only that it sounded like everything was underwater at that point.

"Frisk!" A female voice yelled to her. "Can you hear me? Shit, you're going to need to get patched up... Asriel! Quick! Help me pick her up! We have to get her back as quick as possible!" It was Chara's voice. She wanted to answer her, wanted to tell her that she was still awake and alive, but somehow, she didn't have the strength to do that. Already, her vision was somewhat fuzzy and blurry, making it almost hard to see. And then... She could see nothing. Just blackness. Nothing but pitch blackness. 

Was she dead?
