Star Trek: 10 Times Music Saved The Day
6. Breen Nursery Rhymes - For The Uniform
Michael Eddington once told Odo that the best place to hide something was in plain sight. This little nugget would come back to haunt him when the Changeling displayed his crystal-clear memory, especially amid a criminal investigation.
Eddington, now fully unmasked as the leader of the Maquis, had begun attacking Cardassian colonies in the Demilitarised Zone, eventually escalating to biogenic weapons. These weapons were both his greatest asset and his eventual downfall. The USS Malinche, damaged as she was by the Maquis, still managed to intercept a coded Maquis message - one that sounded like Row, Row, Row Your Boat if both the singer and the audience had broken glass in their throat and ears.
The Breen nursery rhyme hidden within the message held no special meaning, other than the fact that it was Breen by nature. This tipped Odo off to Eddington's earlier clue, as he remembered the Breen colony on Portus V. Eddington would need cold storage units for these biogenic weapons and, as Sisko muses, no one knows how to keep things cold quite like the Breen.
They hit the road and discover Eddington in a fresh heist, none too happy to see them.
