You know, it's so easy to label Seska as Eeeeeeeevil, but - like Annie Skywalker - she, too, had good in her. Ha! Yes! Let's talk about GOOD, here, for a minute, OK? Like Annie's pure as New York Snow & Secret Wife Padme Amadala, who gives birth to twins and then ups and dies, having "lost the will to live" for no reason a bunch of poorly-rendered CGI puppets can figure out. Other than, maybe, she just doesn't want the responsibility. And who's she giving them to? Her husband, the Yeungling-Killer? To the Jedi, who are in Season for being hunted? Who's going to get these kids - or did she not care about that?
Seska ... though ... Seska takes care of her baby. She even brings him to the EMH, to make damn sure he's healthy and we see her burping him and rocking him and all those things mothers are supposed to do. The point is ... she sticks around! Not that we expect to reward her for it, just saying that she's not the kind to up and die, on a whim, just to get out of dealing with it. Though she DID die, eventually - yes, but more accurately, she was killed. See ... there's a difference. She didn't want to die.
Wait! You know ... in Padme's case, we're just trusting the word of a CGI puppet that she's dying for no medical reason. Is that facility even sterile? We see Kenobi wandering in and out in his filthy rags. What CGI Yoda might've dragged in, only ILM can say. And nobody says a word, not a WORD about it. Hey! It's OK! Come right in, don't bother wiping your feet off ... no need for a hospital gown ... make sure you paw everything, too!
