"Elizabeth, can I have a word with you, please?" Harry calmly requested her, he looked like someone who wouldn't force her to talk if she didn't want to, and also because Liz had a good opinion of him and he looked very calm she agreed to have a word with him.
Then harry took her to the side and they talked to each other for five minutes, Will and Catherine couldn't hear anything as they were standing a bit far from them so they looked at the other two anxiously, they were curious and wanted to know what they were talking about but these two were scared of pissing off Liz any further so they stood at their spots and didn't even dare to move, after few minutes Harry and Liz came back to them, Liz looked much calmer than before, she was not furious anymore.
"I am sorry for overreacting, let's go and have breakfast, I am very hungry." Liz looked at both Will and Catherine and politely apologised.
