Nitpick: It is odd that for the overwhelming majority of the episode, the "children" don't seem to remember their entire lives until this point, or why it's time for them to die. Only in the last scene on the moon does Tressa say that Tuvok reminds her of her grandson.
Nitpick: If these people mature by growing smaller and younger looking, it makes one wonder how they are born.
Tuvok: I cannot protect you from the natural conclusion of life... nor would I try. Vulcans consider death to be the completion of a journey. There is nothing to fear.
Ensign Bennett: All this time, I thought I was so lucky... no family back home... nobody to miss. Now it seems kind of sad not to leave anybody behind...
The Doctor: Ah, visitors. Welcome to sickbay. I'm the chief medical officer.
Janeway: This is first Prelate Alcia of Drayon two.
The Doctor: It's an honour to meet you. We don't often recieve such distinguished guests here - unless there has been some sort of accident... Uh, I... I'm sure nothing unfortunate will happen to you on your visit here. But if it did, you can rest assured you will find yourself in very capable hands.
Janeway: When I was a science officer I always envied the captain's priviledge of making first contact with new races.
Chakotay: I envied it so much I almost got shipped back to the academy for remedial training. On my first assignment, we were sent to make first contact with the Tarkanons. I studied all the information we had about them, and pestered the captain into letting me be part of the diplomatic team. When we came face to face with the Tarkanon delegation, I very proudly made the traditional gesture for hello, not realising that males and females of their race use different styles of movement, and I was actually propositioning the ambassador.
Tressa: What were you doing to him?
Tuvok: I put a stasis field around his body to protect it, until I can take it back to my ship.
Tuvok: Some cultures, like Mr. Bennet's, consider an appropriate burial to be a sign of respect.
