The detail everyone agrees to forget until it ruins everything.
means An unfinished or unresolved detail left dangling after a task, deal, or story is supposedly done.
from Straight from the physical world of rope and thread: a 'loose end' is the bit of cord that's come unraveled or untied, not bound into the knot or weave. Sailors and weavers dealt with this literally — a rope with a loose end could unravel entirely, or trip someone up on deck. By the 1700s the phrase was already slipping into figurative use for unfinished business, and the idiom 'at loose ends' (feeling unoccupied, adrift) followed the same thread of logic: something, or someone, not yet tied down to a purpose.
