Yeah, that's that STAR FLEET training, for you, that lets you get back to life, without missing a beat, regardless of who dies. Unless, of course, it's one of the main cast. You know, say what you will of the TNG episode Skin of Evil, I love it how, during Bev's attempts to save Yar and the meeting afterwards, where everyone's talking over eachother, the crew doesn't just "get over it." And, of course, when Spock offers up his life in STAR TREK II, even Shatner emotes in an appropriate and memorable way -- SHATNER!!! But, yeah, if you're a nameless extra, or somebody we hardly, or don't even, know ... ehh ... shit happens. Whatcha gonna do ... ? You know? What can you do. Grab a hold of a hot member of the opposite sex and thank god you're alive like Chekov does, might be a good start, come to think of it.
