There's some dialogue from Lara Hoffman that seems to hint at an earlier relationship of some kind with Barnabas. He seems to have a vague memory of an earlier encounter with her but Lara neither confirms it or denies it. Was this meant as foreshadowing of whatever project that Lara Parker was supposed to do for Innovation?
Also, her throwaway line about child, what have you done has always puzzled me. The logical assumption is that she's referring to Julia. She is, after all, Julia's aunt. (Or, in a soap opera twist, could she possibly be Julia's mother? Probably not but it would make a nice parallel to the Elizabeth/Vicki connection.) I remember hearing discussion that Lara Hoffman was supposed to have some connection to Angelique but the character is really not developed enough to give the idea any credibility.
