This episode uses water imagery for trouble, past events, and arguments. Since the collection already covers “in hot water,” “in deep water,” and “keep your head above water,” this guide focuses on three other expressions: moving on from a past event, checking whether reasoning is convincing, and discouraging an idea.
Cultural note: The source uses “water over the dam”; many speakers use the variant “water under the bridge.” Both frame an unchangeable past, but telling someone to move on can sound dismissive if they are still dealing with real consequences. “Throw cold water on” describes discouraging an idea, not necessarily offering a useful critique.
