U2 biographer Bill Flanagan credits Bono's habit of keeping his lyrics "in flux until the last minute" with providing a narrative coherence to the album. Flanagan interpreted "Achtung Baby" as using the moon as a metaphor for a dark woman seducing the singer away from his virtuous love, the sun; he is tempted away from domestic life by an exciting nightlife and tests how far he can go before returning home. For Flanagan, "Tryin' to Throw Your Arms Around the World" on the album's latter third describes the character stumbling home in a drunken state, and the final three songs—"Ultraviolet (Light My Way)", "Acrobat", and "Love Is Blindness"—are about how the couple deal with the suffering they have forced on each other.
