Not a tweak — the tide itself decided to flow the other way.

means A profound, almost total transformation into something quite different — not a small adjustment but a fundamental shift.

from Coined by Shakespeare in 'The Tempest,' where a spirit sings of a drowned man whose body doesn't decay but transforms: 'Nothing of him that doth fade, / But doth suffer a sea-change / Into something rich and strange.' The phrase named a literal, magical transformation worked by the sea — bones to coral, eyes to pearls — before it drifted ashore into everyday language to mean any deep, startling metamorphosis.
