The illogic of the whole situation.
- The entire universe endangered? Fine, zap one Lazarus. Hell, why doesn't sane Lazarus just vaporize himself? Problem solved.
- How are the Lazurii switching places without going to their ships? If the ships are a necessary component, blow one up.
- The crew act like idiots. The universe is in danger and they let this nut wander the ship without an escort.
And that's just the broad strokes.
