1. I would love to read a story where Slimer turns on the Ghostbusters and frees all the spooks in the containment unit in order to gain some power or self esteem. I think there was a cartoon episode where something like that happened.
2. Second story: Realizing that there's years worth of work catching ghost contained in one area, some real powerful entity tried to release the ghosts in the containment unit to be used as his spirit army. Or maybe ghost were allowing themselves to caught to gather their forces and then stage a war once the containment unit is overloaded.
