Seriously, I'm honestly expecting the siblings to go running through the forest chased by beasties real and imagined. As they vanish over a hill, you see a rather annoyed Alice snapping one monster's neck with one hand whilst blasting another back through a tree-trunk using a nanotech kinetic blast (shades of Mass Effect biotics) with the other hand.
They'll arrive in town and find no-one with the possible exception of a night watchman around. Gavia will spend a whole strip calling Ardent an idiot. Ardent will insist that someone has to come along and, reluctantly, Gavia agrees to wait with him, sitting at the base of a statue in the town square. Next panel is Jack and possibly Miss Margaret Wheelwright waking them up as the square fills up as the town awakens post-dawn.
It's difficult to judge, by my guess is that Chapter 2 will probably end with the end of the initial conversation between Ardent, Gavia, Maggie and Jack. Ardent will be complaining about how everyone is willing to give Gavia a free pass because her being mad with him "explains everything". The very last panel will probably be the scene below reflected in Alice's eyes as she watches from the eaves of the roof of a nearby building.
Chapter 3? My guess it will start with Alice on the roof; her concentration is broken by Doc, who just happens to live in that apartment. By his conversation with Alice, we learn a bit about her background and connection with the town (I'm expecting her to be older than she looks by decades). Meanwhile, the serious 'The Origin of the Witch' strips will be balanced with Ardent and Gavia exploring the town with their two new acquaintances.
