You know i relistened to Moving Target a couple days ago and honestly can't stop thinking about how we couldn't have gotten the arc Big Finish is giving Suzie if she hadn't died the first episode. Like when we meet her arc's done - TKKS is just the final nail in the coffin. And now BF is telling her arc because there's no where to go - she's dead, she's died more than once yes but what was she before the glove, before Torchwood. And ( I still haven't listened to the last love song so no idea where it is set ) even when we see those glimpses, the narrative just beats down that this is a tragedy in the way prequels often are. Suzie's a doomed hero ( in a way ) and her fate is inevitable, and throughout the audio she's trying so hard to do the "right" thing, until she does the hard thing and maybe good, but it still feels wrong and one step closer to the road to hell. She tries to protect Alex but once she learns how meaningless and sad her life will be, she kills her - putting her out of her misery, sparing her all that heartbreak and getting rid of her because she's not important, after all and it seems that Suzie can't do the "right" thing. She tries to do it but she fails. In a way her actions are a lot like Jack's in Small Worlds. Protect the girl until you sacrifice/let her go for the greater good. But in both choices there is judgement that it was the wrong decision be it from other people or the inevitability of the future and your actions then. Suzie killing Alex should have been a hard choice made for the betterment of the world and oh is Torchwood not rife with these but her looming fate makes it not quite that. It makes it not quite right, not as grey as it should be, somehow wrong.
