The Keeper:
One judiciously placed case of dynamite would likely be more than adequate to turn the Stanton Street Cemetery into the Stanton Street Chasm.
We need more than one case, then, for the other cemeteries. :D
*ahem*. Since he'll now have to wait for Vicky to call him back (if he hasn't direly offended her) Jake will consider staying still long enough once informed of the prospect of prisoners to think this out and get some equipment...
He'll want the torch, gun and crowbar, of course, and might as well take his lockpicks in case of shackles, will still grab the nearest stinky and/or caustic cleaning chemicals (maybe pausing to source tinfoil if there's Drano), and will advise Arthur to make sure he has spare flash equipment and everyone else in general to grab first aid stuff in case.
