If Maxen and Remo were a character in a horror film, they would die first. That was what Cosette and Luke initially thought when they proposed to check where the sob was coming from. In their defense, it was probably someone getting locked up in a room and couldn't go out.
Well, that made a bit of sense, but there should be doors banging or crying for help, right? But no. What they heard for a couple of minutes was a girl's faint crying echoing and amplified in the silent hallways of the building.
Maxen and Remo told the two to leave the premises and wait for them. But alas, since Cosette and Luke were both scared, they obliterated the idea aggressively. Furthermore, in most horror films, the common stupidity the characters would do was to split up.
There was no way Luke and Cosette would do that. Over their dead bodies.
