Re: 8:01pm.
Stephen - NOT THE LEAST BIT SURPRISED! Will use his magic to help contain the fireworks so they don't hurt anybody, transporting people away if need be... he'll leave the killing of Gremlins to others.
The Doctor - Also focuses on helping others.
John - usually carries a concealed weapon and tonight is no exception. He pulls out his pistol and is careful not to fire into any crowds, but manages to take one out.
Kurt - BAMFs around to try to stop any Gremlins from fleeing the scene.
