Ian and Dave are back for three more episodes of Firefly. In "Ariel" Simon hires the crew to help him and River break into an advanced hospital to scan River's brain. In "War Stories" Wash and Zoe's marital difficulties lead to Wash joining Mal on a drop, only for them to both be captured by a vengeful Niska. In "Trash" Mal comes across Saffron during a smuggling job and she offers to let them in on a profitable heist if they can put aside their past. One episode fails the Probert Test, they sing the praises of Alan Tudyk, and invite speculation about Ian's fetish.
