I certainly hope she is here to stay, not like last time. If Helena can menace PC almost continuously for 15 years (and not end up in a pool of lye), why can't Heather? I like how Luke seems more frightened of Heather than Helena; In fact, it would be nice to see the two H's teaming together & really give Luke & Tracy something to shake about!
Robin is a most welcome addition to the list of returns to "GH" in 2012, and all of the historical references to characters past (Diana Taylor, Susan Moore, Jeff, Ruby, Rose Kelly, the MIA Bobbie) is a great tribute to the show's upcoming 50th Anniversary!
