"FTL travel - that's faster than light, right?" Leon seems appropriately wowed by that, eyes going wide like a kid who's, well, just been told FTL travel is possible and he's talking to a real astronaut. He's tempted to just let the question hang until Gaeta answers it, but he's been asked one in turn, and it'd be rude to derail the conversation entirely.

"Yeah," he says, nodding. "From the United States, in 2004, if that means anything to you. If not, don't worry, sounds like any dates and places you throw at me won't mean much to me either."

He does not pick up on any weirdness about the word Earth, too distracted by the astral elephant in the room to notice any subtler cues, intentionally obscured as they are. This may be part of why he was doing so poorly at poker.
