The other scenes were all right, but not too engaging. The banter between the desperate Juniper and the rough commanding officer was nice, but the fighting seemed too rushed.
Juniper Maringold is kind of a cheesy name, as is Krimzon (Kzin plus crimson). And why is an alien named Desmomd? The other complaint is the lack of proofreading. A word seems to be words missing from several sentences: "Save the thanks for after we this, kid." "...Which sprouted a good inches from Juniper's rump like a misshapen tail." "...But she certainly wouldn't put with an empty stomach, not by a long shot."
At the end of the day, this is a great toilet scene, and the story and universe are adequate. It would be interesting if you could find other fun scenarios to put this future girl into. The way you describe several characters who don't affect this plot suggests you have other stories in mind that will make use of them.
I admit I was writing it mostly for the eventual toilet scene, and simple tried to make it a sort "day in the life of" kind of thing, but I will fix the errors you mentioned. Also, the names aren't that bad :P Maybe Krimzon, but it's just that I had those "let's make up a full word, then pluck out letters and toss in apostrophes all over it" like a lot of sci-fi/fantasy stories do, just irks me. As for the character Desmond, I wasn't really able to drum up a name that didn't sound too forced/stupid so I stuck with something that at least sounded better than "Barry the alien" XP
Glad you enjoyed it. If you have any ideas on how else to use Juniper, maybe even loosely tie her little universe to your future thing, I'm all ears. Otherwise, I can't really think of much else beyond hilarious hijinks with other "alien" toilets.
