I'm not sure if this is all correct, but according to what I've been seeing, these are the stories that I know of...
Jack, Mute, and a dog: Walking along to the Lodging house (right?).
Flinch, Knickers, Slider, Summer, and Spades: In front of the store, looking for Snickery. Slider thinks he knows what happened, so they are on their way someplace else (the Refuge?)
Slingshot and Spot: Walking back to Brooklyn/The Lodging House (I don't remember which) in order to sleep. Talking about Spot and Sparks.
Rolf, Stuffy, and Spider: Rolf is holding Stuffy and Spider hostage in a warehouse. Spider is hoping Spot will arrive to save her.
