I didn't see this listed as a goof for this episode, and correct me if I'm wrong, but at 43:18, Data uses a English Contraction..."She's correct, sir!" I've watched every episode and movie with TNG cast and can't recall a single time Data has done this. His brother Lore, on the other hand, DID use Contractions. I don't know how I missed this, having seen this episode several times over the years.
