SPINDLE, SPIRE - 
The hours flicker past in footsteps and food. Turns out rodents are a pretty big pestilence in the Spindle and everyone’s got a rat or a cavemouse or something to offer Marceline, and she’s not shy about accepting handouts. The fifth or sixth time she fishes a terrified skittershrew out of a trap it nips her finger and she actually bleeds, bright purple beading up, and she smears it in a circle under her thumb while Bonnibel crowds up at her elbow to look. Next second Bonnibel has Marceline’s wrist in hand and she’s counting to herself, measuring the flutter beneath the thin gray skin.
“Not bad,” she says. “Still extremely low blood pressure, but! Pressure, period. Nice.”
“Whoo! Got the pump-pumps, yo.” Marceline’s feeling good. Feeling great, more on point: she flexes her wrist against Bonnibel’s touch and watches the tendons there stretch, feeling the hum of her own pulse throb up her arm, her shoulder. She has a headache but it’s a worth-it headache, a flooding heaviness that speaks of too much food too quick, all tanks topped off and ready to go. She kills and drains the skittershrew. Handing back the trap to its owner, she squares her shoulders and looses a belch that echoes off the cavern walls in rounds. To Bonnibel she says, “Whoa, yeah, might wanna step out of the danger zone, yikes. My bad.”
