I bet Djinn's brother is going to want that crystal she mentioned in her origin in exchange for her freedom and I bet she hid it in the Bat cave. Remember when Djinn disappeared and went after Damian in the Bat cave issue. We know she isn't the traitor so what was she doing in there? Most likely hiding something. The crystal she mentioned in her origin. I mean Djinn is not stupid the Bat cave is one of the most secure areas in the DC Universe and it's also protected from magic if I remember correctly. Also if something happens to her at least Damian would be able to protect it for her. This is probably going to come up in February.
