As far as I know, it hasn't been confirmed. The only thing that I remember is that there were comments made that Lily would probably not be visible until around the 5th episode.

My guess is that Lily's dad will be a sub plot re-introduced part way through Camelot, and probably will remain a b-level (or c-Level) plot the remainder of the season.
