Seamus hadn't wanted to attend the coronation. Really, he didn't but fact was Brighid said that it may put a good impression on Scotland. Sure, he was exiled from Ireland and maybe he could attend the coronation and see how it went. He was actually impressed by it and everything.
And then the spells started, Seamus had thrown himself into seeing if he could save someone or at least protect them. When he saw the queen of Scotland get hit into the wall and the shield fell. The least Seamus could do was help the queen out as he darted over to help her out.
"Are you alright, Your Majesty?" he asked, knowing the answer already, but he had to be formal and not rude. He offered a hand to her as he leant down. He wanted to get her up and to a safe place, but right now, he had to get her permission before he could do just that.
