A cutscene explaining why the Medium is there, and provides context as to why the building is locked down and everything. Meanwhile, the Wraith has some time (maybe 15-20 seconds) to prepare. Switch to Material plane, lay a few traps, perhaps possess someone? The cutscene is totally out of scope, but I think the idea of a "prep" period is cool.
