Well, to sum it up, the old Investigation Group is going to war trying to get to Abigail in time.  Persona spells and attacks, as well as the hosts themselves, are going all out at the moment, clearing a path to where she's hidden with her clone at the moment.  So long as you stay true to their powers and all that, all of which have ultimate forms of their Personas, I don't care how you handle it pal.
