Matthew says Jenny tries to “collect[]” her destiny, which emphasizes the fact that most of Jenny’s feelings, words, and experiences are second-hand. They already existed and she simply picks them up and claims them as her own. This is what Jenny does to Robin: collects her. This also means that Jenny’s love for Robin, at least at first, isn’t genuine. It’s not quite the intense, sincere love that Nora has for Robin, but instead a pale imitation of it.
