There really wasn't anything Percy could have done to prepare himself for what Marguerite's answer would be. And really, he wasn't really expecting anything absolutely drastic. Sure they were outside instead of inside, in a place that obviously wasn't Paris and Marguerite was in strange clothing. Very strange revealing clothing, but that wasn't the point. There was something that could explain all of this, but Percy would never actually be able to guess what was behind this turn of events. Right now he was starting to favor that he'd hit his head and was having some strange hallucination or something.
Though when Marguerite told him it would take a bit to explain, that's when Percy grew worried. So with a somewhat confused look on his face, Percy walked along with Marguerite his hand in her own.
"Safer? Have things gotten more out of hand with the revolution?" Percy well knew the state Paris was in, he'd been in and out of it enough times to have a good grasp of what the city was like. And despite knowing they weren't in Paris, when Marguerite used the word safer, his mind just automatically jumped to there being conflict in the streets here, which had him slightly on edge, glancing around as though he expected soldiers to come around the corner at any moment and try to drag them off.
The Bible? Now that was interesting. Though the year 2012? In America? That was...well, completely and utterly unexpected.
"What? We're in America in 2012?" He looked at Marguerite, his mouth hanging open slightly and his eyes wide in shock. After all, how else was he supposed to respond? People didn't just suddenly move forward in time by a couple centuries! "I know it well enough, why? What's the Bible done to anyone aside from being preached by old men ad nauseam?" Humor was a very wonderful mechanism to stave off shock and to help him process this sudden and completely unexpected and highly improbable change of scenery and time. So really, he was just going to wait and see what else Marguerite had to say on the matter.
