A ghost is, in most tellings, the spirit of a person with unfinished business on earth. Sometimes that business is vengeance; sometimes it’s simply an inability to let go. In Double Walker, it’s both.
There is a scene early on in Poser in which Lennon (Sylvie Mix) and Bobbi (Bobbi Kitten) play the mirror game. As Bobbi moves, Lennon mirrors that movement until after a few minutes, Bobbi explains, Lennon’s movements will begin to inform her own. Then, after a few moments more, they won’t be able to tell who is mirroring who.
This scene is a condensed version of Poser, a story in which a young woman with difficulties interacting with others ingratiates herself in the Columbus, Ohio indie music scene by emulating the people she meets. If you’re picking up Single White Female vibes you’re not exactly on the wrong track.
