1. In S1 E17 - Manhunter, James Harper knows about Cadmus and talks about it like it's a secret government project. Is it really a government sponsored or funded (off the books of course) project, or is it not government related and James Harper was secretly a member of Cadmus?
2. In S2 E1 - The Adventures of Supergirl, why does Cadmus / Lillian Luthor want to kill Lena? Just because she's renaming Luthor Corp? I just don't see the motive, especially since Lena is her daughter and she'll need her later.
3. In S2 E7 - The Darkest Place, how does Cadmus know there is a secret project named Medusa inside the computer in the Fortress of Solitude? How do they know to even ask for it and then refer to it by name?
4. In S2 E12 - Luthors, why does Lillian need Lena's hand print to open Lex's vault? Shouldn't her own hand print have worked since she's also a Luthor?
