This week is a bit of a tour de Lachlan de force you could call it, as Tully and Grace get to learn all about flags right on the air because Lachlan did too much research! Flags are used by every country and by countless other groups as a symbol of their strength and unity, but why? Why were they so important in historic battles? And why exactly do different flags look the way the do? Find out the answers to these questions and relatively little else because the answers are kind of complicated this week on Dungeon Deep Dive.
