they call it a donit 'cause don't it look good
Bart's cousin Zeke lacks most of the charm Billy found tolerable enough to help him surmount the challenge of befriending someone so ineffably outgoing, so irrepressibly incorrigible. And Billy is no stranger to being long-suffering.
In other words, he's - Zeke's - too much, and way too much of it. The fact that his "straight-woman" partner matches all his poses beat for beat and sports lightbulbs on her shoulders and in her hair is yet another sign of danger. And Billy is no stranger to signs of danger.
And then there's Ashera, who won't explain how or why she knows the Genbus and doesn't even seem to care, for her own sake or for anyone else's. To speak of incorrigible...
Ashera carries a twinsaber, and Zeke a colossal electrified greatsword with a blade wide enough with which to play pickleball. They surely don't need these things on them at all times; even Billy has gotten generally socialized enough to leave his guns at home, most of the time.
But no, one surely does not have a present or absent need for weaponry on a trip to a local ice cream parlor that doesn't even take credit payments. If not for the freezers, the place might be entirely analog. Rather, unelectrified - which is not (no longer) an option, with Pandoria and Zeke here.
