The trek back to the scene of the accident will go much the same way as the first; if Akechi has an especially sharp memory, he may realize that the sounds of nearby trains occur in the exact same pattern with the exact same frequency as before. As mentioned, despite the time that's passed the accident still looks just as fresh as it had a month ago, the blood still wet, the body still missing, and the mysterious smear of blood still leading deeper into the tunnels.

Following the smear will reveal it to go on for nearly fifty feet, much longer than should be possible, before it comes to an abrupt end. There's still no sign of a body, nor any signs of footprints, pools of blood, blood droplets, or anything else to indicate that whoever was here either stood up or was carried away. It's like they simply vanished. Once they reach this point the sounds of passing trains cut off as abruptly as the trail of blood, leaving the two of them in silence.

There's a final noteworthy point of interest to discover: set into the wall behind the maintenance walkway is a door labeled AUTHORIZED PERSONNEL ONLY. A quick investigation will reveal that it's locked, but it's also an old, rusted, and completely mundane door. Tracking down the key is an option, but the door may be vulnerable to more unorthodox methods of forcing entry.

At this point, you may create a post on the game's log community so that you can begin playing out the subway exploration. However, all information on what Akechi and Akira can expect to discover will still be communicated via PM.
