Our Lower Deckers have trouble bonding with Ensign Jet Manhaver, who has been assigned Boimler's bunk and shift duties. Meanwhile, we get a glimpse of Boimler's life on the U.S.S. Titan, which is more intense than he thought it would be.

• This episode introduces the new chief of security, Lt. Kayshon. He is the first Tamarian in Starfleet. Tamarians were first introduced in the Next Generation episode "Darmok".
  
• A transporter accident creates a copy of Boimler, as it did to Riker in the Next Generation episode "Second Chances". While the newly named "William" Boimler remains on the U.S.S. Titan, the original Bradward Boimler is transferred back to the U.S.S. Cerritos.
  
• Jet Manhaver appears with the rank of Ensign, despite being seen in two earlier episodes wearing the pips of a lieutenant. He brushes the extra pip away, making a joke about it being a kernel of corn.
