Question: The ever-popular gag in this episode is that Worf consumes prune juice for the first time and declares that it is a "warrior's drink," to Guinan's amusement. However, Worf was adopted as a child by human parents, he grew up on Earth, he was highly educated and graduated Star Fleet Academy on Earth. Given the reputation of prune juice as a natural laxative throughout human history, how could Worf not know what prune juice is, having lived most of his life on Earth?
Question: I can't tell if this was a mistake or if there's an explanation. When the Borg are on the Enterprise's bridge, the first two are covered in the green light indicating they're being transported back to the Borg ship, but the 3rd one (the one successfully shot by Worf) has no lights, he just fades away. Why?
Question: The motivation for this episode seems to be returning the Enterprise 1701-C to its own timeline 22 years in the past, where it will certainly be destroyed by Romulan warbirds; yet, the heroism of sacrifice will avert a protracted 22-year war with the Klingon Empire as well as avert tens of billions of Federation deaths. QUESTION: Why didn't they just SWITCH CREWS and send the far more advanced Enterprise 1701-D through the time rift and 22 years into the past? Using its advanced weaponry, defenses, and sheer speed, the Enterprise D could have easily defeated the old Romulan warbirds, saved Tasha Yar, averted the 22-year Klingon war, and saved 40 billion Federation lives. Additionally, sending the truly futuristic 1701-D into the past could have then exponentially advanced Starfleet technology into the future, making the Federation virtually invincible to its traditional enemies. It would seem that this would be the more noble, heroic and logical action of a Starfleet crew - to save lives and advance Federation survival. It would have certainly been a more thought-provoking episode, anyway.
