SCP Foundation

The SCP is two individuals who manifest by emerging from any type of door in our world. Or the SCP is the manifestation themselves? I'm not quite sure which is more appropriate. Anyway, I'll call person one A and two B. A always emerges, usually in public, and will attempt to hide or continue running away. Shortly after, B will emerge from the same door, and will try to find A. He is usually heavily armed, and appears intent on hunting A down and catching or killing her. They will make a scene in public (or private) and A will always escape through another door, with B close behind. Whatever second door they go through will always cause them to vanish. Then the pattern will repeat sometime later. This isn't a manifestation or loop phenomenon; the two are in one continuous chase in real time. The door phenomenon is a part of this, and is linked to A, which I'll try to explain.

A is a woman around 30 or so years old. She's always seen running away from B, although on some occasions she will fight back and attempt to impede his progress. She has no qualms about using bystanders as a means of protection, although they never end up hurt. A is actually a low level reality bender, who alters the reality around her based on her subconscious desires. Her powers are linked to B's desire to catch and or kill her, and is also partly responsible for why he is unable to do so; she doesn't want him to, so she bends reality to match. Her ability is like the greenhouse effect; the more she stays in one place (or reality) the stronger it gets.

The fact that both she and B can use doors as means of transportation is linked to both her ability, and his history.

Now I know the immediate concern is; wait a minute, if she doesn't want to get caught, why doesn't her ability make this happen by stopping B? I'll get into that in his section, and the story one.

B is a heavily armored and armed figure that is responsible for chasing A. Despite his usual arsenal, he prefers not to involve innocents in his pursuit of A, something she uses to her advantage.

B (and A as well) are from a Government Agency similar to both the Foundation and the UIU in another dimension. The Doors are one such anomaly that was studied, and it links to any door in any dimension.

B is effectively immortal, as a result of his history with A. He uses this to his advantage, as he isn't afraid of dying to anything in our world. His goal is to catch A and force her to return to their original dimension, or kill her to prevent her from using her reality bending to change our world.

So, what's this got to do with anything? Well, my idea for the narrative is this:

Backstory:
B used to work for the agency that was responsible for containing A. The two were close, and the agency used this to keep them both in line (Her abilities influenced things as well). One day, something happened (I still haven't figured out what) and her ability went crazy, tearing her reality apart. She was forced to pierce it back together, but only out of the knowledge and memories she had herself. As a result, her home world is effectively a patchwork landscape of famous sights and places. B, who survives do to his closeness with her, doesn't know that she caused it, so the two of them set out. At some point, her desire to keep him safe turns him immortal after he suffers an almost fatal accident. When she confesses she is responsible for what happened, he turns on her, and she uses the anomalous doors from her dimension to flee to others (including our own). He follows.

Although her ability would suggest that she can stop him from chasing her, she is actually guilt-ridden over what happened, and this is what allows him to follow, but never quite catch up; she wants to be punished for what she did, but isn't quite ready to die for it.

This is basically the setup for the SCP itself. Most of the information would be expressed through either field reports, or on the spot interviews (neither A or B are interested in stopping for a formal one).

As for the narrative of the SCP itself, after all the relevant information has been given, maybe the Foundation is able to send a researcher with B, and get his side of the story. He explains that the only thing keeping him alive is the fact that despite their animosity, they both still care for and love each other, and so her ability prevents him from losing his immortality. At the same time, he isn't sure if his inability to finish the chase is due to himself, or her. The researcher would maybe suggest that they aren't getting anywhere because they are just running away from their responsibilities and problems, and suggests they at least attempt to talk it out. Although B would initially laugh this off, I've got two ideas for where to go:

Ending A: B actually ends up catching up to and killing A, then falls apart into dust, due to losing his immortality. The SCP is neutralized.

Ending B: B catches up to A, but the two of them end of talking, and tentatively reconciling. They both go back to their original dimension with the hope of slowly restoring it. The SCP is pending neutralized.
