Could Percy really be blamed for being protective? It was part of who he was, part of why he was the Scarlet Pimpernel. He always moved to do the right thing, and he would always do what he could to protect Marguerite. Even during the time when he thought she'd betrayed him, he still protected her because he loved her. He could have just divorced Marguerite or turned her away after he learned about her part in what happened to St. Cyr and his family. But he didn't do either of those. The thoughts never even crossed his mind, even when he was in his deepest despair over it. The fact of the matter was, he loved Marguerite so passionately, he would do everything he could to ensure she had a good life because it is what she deserved. And he would never turn away someone he loved like that.
But at least their secrets had finally come to light, and they now knew the truth about each other. He had made the right choice, and he'd at least held to his convictions, even if his heart had broken. Now, though, it was whole again because Marguerite knew he was the Pimpernel, knew that he was doing everything he could to save people from being senselessly murdered. The revolution had started out well, and Percy did understand the need for change, but when it had descended into little more than chaos and bloodshed simply for the act of shedding blood? That is where he took issue.
"Well yes, but still it doesn't make them any less droll and heavy." Percy knew it was a serious situation, any kind of fighting was, but the more he let Marguerite's words sink in, the more he found himself finding this place to be rather dark and heavy. An atmosphere that didn't seem all that different from the state Paris had been in. Looking at Marguerite, he nodded a bit. "So we are to assist in this fight, which is why we are here? Even if we aren't, I'd be demned to just sit by idle." All ready his protective, heroic side was showing. Percy wouldn't exactly call himself a hero, he just did what he believed to be right and would throw himself into it completely when given the chance. Once he adjusted to things properly, obviously.
Following Marguerite into the building, he glanced around, sizing it up a bit. It seemed a little odd, though he didn't say anything. He wasn't going to complain when it was free lodging for people like them. And Marguerite clearly knew her way around. Though when he was handed the amulet, he took it and looked at it, blinking in slight confusion at it's purpose. So once they were in the apartment, he looked at her.
"What's this charming little amulet for?" Then he thought for a moment. "And perhaps some tea. Or something slightly stronger."
