Just watched the episode again; always fun when TNG plays with time. This was a fun mystery.
Anyway, at the end of the episode, everything is returned to normal [Spoiler?] – the power transfer is stopped, the hull breach is prevented…and the Romulan ship disappears.
Data posits that the Romulans “returned to their time continuum.” But when/where is that? Wasn’t their continuum the same as the Enterprise, since the vessels were communicating with each other and sending Romulans aboard?
In the ensuing Captain’s Log, Picard says (but we’re not shown) the Enterprise did indeed evacuate the Romulan ship and took the crew to the Neutral Zone. But where did they find the ship? And what happened to the Romulans already aboard the Enterprise, like the ones on the bridge?
Memory Alpha just parrots the episode dialogue, with no explanation. Where did that warbird go?
