In the past 10 minutes or less, a bunch of insane psychopathic clowns have attempted to seize control of the Circus by taking hostages. Cutter and Harrier have slowed down, at least temporarily, a group that's in an RV. The group in the RV killed a hostage. Ghost, Luz, and Flicker managed to cut down 3 of them at the back of the train without any hostages getting hurt. One clown went to the front of the train and killed two drivers, as well as heavily damaging the controls. Al has put that one out of his misery, and is attempting to juryrig the trains to prevent them from crashing (unbeknownst to the rest of his crew).
There are 3 clowns in the RV, 3 that were in the back car, and 1 that went up to confront the drivers. There are a suspected 12 total, so there are 5 unaccounted for.
