@AWoman - no they hadn't heard from Nick when they came to the house the first time.
So at that point they might have thought they had run away together.
But a whole day has passed since then.
Fred said something about reporting them missing or getting help to find them as they left the house.
Nick has had time to come around after being knocked out since then. Time to be interrogated. Time to ask to see Fred.
So now, the Waterford's might have spoken to Nick, been told what happened, and come back with or without Nick knowing June had been abandoned as the guards didn't know she was there when they took Nick.
