What is the danger?
What is the item at first supposed to be or do? Is it lackluster and boring to build upon later or immediately enticing?
What does the "vacancy" represent? The SCP itself represent?
The vacancy is a representation of the stages of grief. In a sinister way. The tunnel is allegorical.
Those who accept their trauma (or themselves to some extent) get turned into the vacancy. They haunt the tunnel. Ally accepts herself but at the cost of losing everything in the beginning of the narrative. She has no where to turn to but inward.
Flora / Ally confide in one another for the briefest moments. Hints at their romance but stays on their friction and inability to confess (1960s and all).
Those who do not accept their vacancies fall into their cooping mechanisms and receive the worst punishment imaginable: they live. They continue on. They live on as if Ally never existed in the first place in the epilogue.
What draws these people to this place? (The SCP is a character itself).
How do the characters interact with the tunnel?
What is their interactions with eachother? How do they hurt one another?

Title: Journeys End At Lovers Meeting
Item #: SCP-X
Object Class: Safe
Special Containment Procedures:
Description: SCP-X presents as a tunnel with a man-made water channel that terminates at an extradimensional vacancy hereby designated as SCP-X-A. An acrylic imprint titled "Journeys End At Lovers Meeting" consistently manifests on surfaces adjacent to the entrance, despite removal attempts.
Prior to SCP-X's discovery by the Foundation on August 1st, 1962, it was used as an amusement park ride for a carnival situated in Hendricks County, Indiana. Individuals that had traversed the expanse described an increasing lack of identifiable landmarks as they journeyed closer to SCP-X-A, of which came into view as a space devoid of noteworthy attributes. Signs, walls, thematic artifacts, and lights by SCP-X-A's dimensions appeared absent. What remained is a body of fluid, with the tensile consistency of water, which pervaded the stream pathway.
Contrary to SCP-X's linear architecture, individuals who had consummated their voyage assumed it was circular by design, as, upon nearing SCP-X-A, they had reversed course unknowingly and sailed to the entrance.
Ingress into SCP-X-A has been recorded; however, the requisite triggers behind entering this space are unclear. As such, the Foundation has repeatedly failed to mount a proper expedition, and has solely relied on the testimony of accidental trespassers (hereby designated SCP-X-B subjects). Scanning equipment has failed to yield what lies beyond these parameters.
Once inside, SCP-X-B subjects experience contrasting feelings of perturbation and pleasure. Furthermore, they will hear of guttural groans from an unknown source. All accounts preclude objective measurements of SCP-X-A's interior, with several that attempt to articulate that SCP-X-A is exceedingly boundless.
The process of escaping SCP-X-A is unclear. Near-universally, SCP-X-B subjects exit without physical harm. Researchers theorize that psychological triggers allow for certain viewpoints of SCP-X-A, and as such, allows a subject to move along the non-existent area as if it possessed an invisible enclosure, likened to that of SCP-X's perceived architecture. Though subjects have never actively searched for the exit, most navigate through SCP-X-A as if it were a circular tunnel.

Alia: Denial > Acceptance. Goes into the vacancy.
Florence: Anger. Does not go into the vacancy.
Fairbanks: Bargaining. Does not go into the vacancy.
Jackson: Grief. Does not go into the vacancy.
Alianna: So this is new.
Florence: Do you think they know?
Fairbanks: They?
Florence: The management, genius.
Fairbanks: Well, then no - I don't think the bigwigs planned out this mile-long, dark expanse when they made an attraction designed to con horny kids into their "love tunnel."
Florence: Be serious, for once.
Fairbanks: I am!
Jackson: How long have we been here?
Fairbanks: Watch says, oh, couple o' days. Really.
Alianna: Several hours.
Florence: Several hours wading through the dark! Kneedeep in the water!
Alianna: Calm down, Flora.
Florence: What the fuck were they thinking! They didn't even give us oars to row with, Ally.
Jackson: It's a guided passenger boat.
Florence: Who gives kids boats without oars?
Jackson: Boat's electronic. S'posed to run on its own. Like trains.
Alianna: We- we just have to retrace our steps-
Florence: With what? The darkness to the right or the darkness to the left? If my hands were chopped off, right now, I would have no way of telling from where or from what.
Jackson: It's electronic. Some gear must've gone loose.
