It is, however, possible that it may be a form of Monad Proxy (subconsciously or consciously). Kazkis Proxy's conversation to Vincent in which he revealed that he and Monad were lovers as well as Ergo Proxy's depression and grief at seeing Monad Proxy in the tank seem to enforce Kazkis' words.
Also, what she said to Vincent near the end episode of 20, telling him that she hated men that smelled of other women and vise-versa, along with the irritated tone of voice reveal a form of jealousy. If the above is correct, however, it is hard explain exactly how Monad can access Vincent's consciousness and subconsciousness. It is possible that some Proxies can affect other's subconscious much like Will B. Good did to Pino. Or what Senex seemed to have done to the woman in the prison cell.
