"I don't know what is happening, but I don't like it"
"The human is smiling" -- Anon Guest
One of their own writers said it the best: Never trust a creature that smiles all the time, they're up to something. And they were very, very correct. The most frequent portent of doom, next to phrases like, "Hold my beer," or "I think I know what I did wrong," is most definitely a Human smiling in a certain way for a period longer than ten minutes.
It's a sure and certain sign that someone is going to get what the human thinks they deserve. And it was happening most alarmingly on the bridge of the Wandering Star, where the Ship's Human was having an apparently evil idea. The most her crew could hope for was that it was going to happen in the general direction of their current foe.
Who, thankfully, was also unnerved to see a Human smiling at them like that.
