Julia tapped at the bolt with one finger, then made screwing and unscrewing gestures with both hands. The nuts had been doubled, and torqued tightly against each other. Dinah took a multitool from a holster on her belt and unfolded its needlenosed pliers, then borrowed Ivy’s. By twisting gently in opposite directions she was able to loosen the nuts. Julia pushed her away and unscrewed the nuts with her fingertips, then gently extracted the bolt. Her tongue retracted into her mouth. She put one hand over her lips and leaned back against a bulkhead for a few moments, moving her jaw to work up some saliva and get limbered up.
