Ace and others were shocked when they witnessed the Flag and Sword's excessive reactions and heard grave warnings. It was completely out of their expectations.
Zaria was the most startled of them all because it was her first time hearing about the God Runes. Then she saw the two treasures, which were out of her wildest expectation because they were true spirit treasures with weapon spirits as intelligent as her or even more so.

But she remained silent and observed since she was also curious about the 'God Runes' and the reaction of those astounding spirit treasures.
