Both Joneses are in on this! (Anything that allows them to channel their wrathful tendencies is a good thing.) Both parts of it, but definitely the part that involves fighting off the creature.

Killian lives in the Coliseum district, so hopefully his home will be fine, but his about-to-open business is in Leisurebrook, so he'll be stepping up to defend it. He knows how to use a sword, and a gun.

Jessica has super strength and as such does not need a weapon (and probably can do more damage without one). She lives in the Coliseum district, but she'll show up to fight things somewhere else too.
