Lt. Mao'Syllis received a parting gift from the new acquaintance she made on her last day on DS101. Dr. Jason Connor of the Yeager sent blackcurrant juice to her quarters. Lt. Dennis Hanson, the ship's new FO, and the CEO Gabriel Pelgrims also recovered from their night in their respective quarters as they prepared to depart. Speaking of parting, Cadet, now Ensign Nim Lister said his goodbyes to the crew with which he has spent a long and arduous time. The crew wishes him luck. Captain Canon commanded the departure of the USS NIGHTINGALE from Deep Space 101 with Captain Alyza's clearance. New FO Hanson attempted to get comfortable as he ordered the helm to take them into space in anticipation of some trial runs with the newly refitted equipment. First, the crew tried out their new warp capabilities. All went well until a series of strange malfunctions sent engineering crew scurrying in futile attempts at repairs. The test ended with Pelgrims and Kort sustaining minor injuries, and Mao'Syllis seeing conspiracies rooting back to DS101. Later evaluations conclude that the mysterious malfunctions are the work of none other than pesky Cardassian voles. Of course, Mrell is everyone's first thought, and slyly adds to their suspicion. Really, though, the Voles could have come from Lyrr II, DS101 or another possibility. Whatever the cause, Canon and crew divvy up ideas on how to eliminate the varmints, and come to the conclusion that iso- linear tags would be safest. This would result in the voles being transported to a cargo hold and hopefully, the end of the infestation. Meanwhile, Jake Stevens comes to the realization that he will now play a secondary role to the new Dr's wife. He seeks counseling to overcome his sudden lack of confidence. The crew of the Nightingale continued to hunt the pesky voles. Ensign Nimrook Lister returned as the `Gales new Chief Security Officer, a position left open when Hanson took the FO position. Captain Canon put Lister immediately on the vole-hunting job. As CEO Gabriel Pelgrims tried to work through Nim Lister's vole exterminating suggestions, Debra Michaels came to Pel to express her concern for his well-being. Lt's Mao'Syllis and Pelgrims took a moment to eat dinner and get away from the vole hunting and ship repairs. Pelgrims continued to act strangely. FO Hanson conducted the crew in `bag and tag' exercises. Lt. Mao'Syllis tells Lt. Pelgrims to go blow off some steam. Pelgrims continues to act strangely. Hanson, Lister, and Gecko continued to blast voles and corner some into a corridor. Lister got the idea to seal off the voles escape by igniting plasma from a ruptured EPS conduit. The trick worked, but also worked on CEO Pelgrims nerves. He ignites at the new Ensign. FO Hanson goes to Gabe's office to find out why Pelgrims is so moody. In the holodeck, Dennis comes to understand Gabe's pain better as he witnessed a recreation of the death of Pelgrim's fiancé. Seeing the shuttle accident again brought back painful memories that sent Gabriel back further into his painful existence. Gabe decided to see a counselor and then get some much-needed sleep. Dennis leaves his friend alone and goes back to vole hunting. Lt. Hanson laughs at all the damage the voles have caused. Gabriel Pelgrims return to help and contributes the idea to shut down as much energy producers on the ship as possible to divert the Cardassian vermin toward a single power source. He, Syllis, and Hanson appear to "make up". Syllis and Hanson compete for who can tag the most voles. They then make final arrangements to remove the infernal pestilence, hopefully permanently. Syllis and Hanson begin shutting down various areas of the ship. The crew manages to divert the remaining voles into one area of the ship. Then Mrell comes to Canon with an idea as to how to get the voles off the ship. Ensign Lister enters the room to join Hanson and Syllis as they wrap up the vole problem.
