Another good episode, but my observations will have to be shorter this week as I'm busy.
The snowman bit wasn't as silly as I expected, and I liked Archer's quote: "Who's the sculpter?".
The schoolchildren part -- not very funny, not as well done as Captain's Day in TNG, seemed to just be a filler in this episode.
The Vulcan captain, Vanich (sp?), not good on names tonight, I've no idea why he would come to dinner and not eat either, especially as he wasn't interested in humans. Maybe it was just so he could say that to T'Pol, whatever it was?
So, T'Pol is betrothed to an architect, Kos (sp?), and as Vulcan tradition dictates that newlyweds cohabitate for at least one Vulcan year, and it is not logical to have an architect aboard an exploration vessel, she must choose whether to stay. Also her fiancé's family is pressuring her to fulfill her obligation and name a date for the wedding. A wedding she already postponed in order to prolong the assignment to the Enterprise.
Well what about Pon Farr? Someone said how are they going to cover it? Voyager showed that it could be resisted with new drugs and holodeck technology, but that is in the future, in this time period isn't it a case of Vulcan males mating or dying? T'Pol doesn't seem to worry about his health and wellbeing, only her obligation to Vulcan tradition. Maybe marriage ceremonies usually take place before Pon Farr, and Spock and Tuvok just waited until the very last minute, if so then we will be hearing from this fiancé again, and he will probably won't take no for an answer when he does.
Regardless what it was made of, a comet only 82.6 km in diameter would have less than one percent of Earth's gravity. So even walking around on the comet would be impossible.
Excuse me, but didn't a shuttle fall down a hole last week as well? Is this a new Star Trek cliché they're inventing? Instead of destroying shuttles, we're going to have them disappear into caverns each week!
