@Clean,

If you recorded it or have it on demand...In the final scene....pay attention to what the firefighters say.

I missed it the first time, myself.


OR basically they said that though the building was abandoned...the plumbing was till up to code....including the sprinkler system..which is why the building was still standing even after Ghost's arson attempt. They also said that markings on the door showed that somebody forced their way OUT of the building.


I didn't like it either.
