I'm not jealous, I don't get moved by much. I'm not enraged, not insecure as such.
Tension is high after the debacle last night and while Sark couldn't care less either way about anything as long as it doesn't put his or April's life in danger, he's not immune to the feeling, although his tension comes from other, mostly unrelated places. Vaughn being here comes to mind and while that's less of an issue than Romana going nuclear and Jack leaving, it's still something that deeply disturbs him (and honestly when he is ever more concerned with other people than himself?)... Mostly because of the whole issue with Vaughn being from an alternate timeline. It's hard enough being on the defensive when people expect you to do something horrific, adding a laundry list of crimes he has no memory of committing (because he hasn't done it yet and probably won't ever) just makes things even more complicated... And really, Sark can't handle anything getting any more complicated, which just goes to prove how complicated things will get for him in weeks to come, because this universe loves making him uncomfortable.
Well, at least April doesn't like Vaughn in the least bit. He can't help but find that amusing.
Nonplussed by the aura of doom that seems to hang over the area, Sark's in the common room reading, although it's painfully obvious it's just a front considering the fact that he hasn't turned the page in the last fifteen minutes. While there is generally never any emotion on his face, in times of stress, his head is almost constantly in a spin, going over a variety of issues with his world at large and probably not even in the least bit quietly.
It's actually the mental equivelent of a deep existential sulk, if you wanted to be technical about it. He seems to be doing that a lot lately. Well, that's what happens when nothing in your world makes any sense anymore and you're far too dysfunctional when it comes to these things (or everything) to know how to make it make sense. Damn those control issues.
