As far as Wesley knows, there's only one ship named Enterprise currently in service - of course, she's still got a few years of service left in her at the point he comes from. He's already considering a few discrepancies that certainly point to him being from some time earlier than Captain Janeway. Though he's already encountered a few individuals from entirely different realities - some temporal inconsistencies hardly seem surprising. He doesn't know of any Voyager in service, and he does still study up on the fleet, now and again, even if he doesn't pore over schematics with the same sense of fantasy he did before he'd been assigned a real post.

"That's what I had been assuming, though we had no idea exactly how. We didn't detect any kind of temporal anomaly, and I'm still not detecting so much as a single chroniton particle - not that my tricorder's been that consistent here. And from what I've heard talking to people here, a lot of them just wound up here, without any kind of explanation. Which means we need to find some commonality..."

His thoughts running away with him, he stops for a moment. Time to address... time.

"Captain, can I ask what stardate it is, where you came from?"
