3 Works in Michelle (Zerophilia)
Point of view of Max/Michelle. I think he/she had an inkling that Luke was a Z fairly early on. To me, Max/Michelle was the more compelling character.
Michelle tries to sort out why she's so damn mad at Luke.
Max says he feels the same way about Luke as he feels about Luca, and Michelle says the same. But Luke doesn't know if Max or Michelle is just so used to being a Z, so used to knowing what they want, that neither of them notices that it's different.
