These are both such great options. I was giving it some thought/going back through some info pages in case I had any follow up questions, and I have one! But I think just the one.

If I were to go with the second option and brought her in as a ghost and I were to play her still mostly according to ghost rules, would this mean she could be seen/heard but perhaps still only physically interact with setting important items? (I'm thinking specifically about the id card, journal, pocket watch, etc., but other things may come up in events as well.) Or would she have total physical presence, only still be essentially playing by the rest of the rules (always in the same clothes, no need to eat, not many bodily functions to speak of, and so on)?

I just want to have things in order before I try to hit up the tdm.
