So Kara comes back love-obsessed and with a head!Daniel. And is convinced that Leoben is the key to her finding Earth, to the point that she makes him her top priority, which she never does in canon with any man ever for a moment. I do wonder what she is, in this particular scenario. I'm guessing you didn't angelify her, but she still seems not quite what she was. She sees it as love that transformed her, and that's a very interesting way of thinking about it.
