Q; How could the Enterprise navigate by Dr Mannheim's co-ordinates when he only gives two of them?
A; My opinion is that the origin of the distress beacon acted as the third point of triangulation. They got there, didn't they?
Q; How does one equate Janice's statement that she waited for Picard all day at the cafe, on a day when it rained all day, with the fact that it was an open-air cafe?
A; We might assume that it was a gazebo-type cafe, with a glass roof extending over the perimeter of the restaurant, as was (ahem) the fashion in those days. The reason we don't already know this is because never once do we see the roof of the restaurant.
Q; How come the Eiffel Tower changes places in the background of shots in the cafe scenes?
A; I can't say I'm sure that it does, actually. I've been through this scene several times, but I can't make up my mind about it. Anyway, for me the real puzzle about this Parisian cafe is why does everybody there speak in English? Picard is French, the clientele and staff are French, so why do toute le monde parle en Anglais? I think the whole thing should have been done in French, with subtitles, just to make it all more authentic. Or maybe they did speak in French, but the Universal Translator obligingly translated for our benefit . . .
Q; Just as Data is about to seal the time-rift, he says "It's me!". How can he do this when he can't use contractions?
A; He can use contractions, he just doesn't know it. He's done it before several times.
Yet another ending here where they all comfortably settle down on the Bridge and stare at the view screen. What do they do on the Bridge all day, knit? Stare at the stars? Don't they get to see enough of them?
