Who do you think is holding Robin

captive in what appears to be a hospital room or is that psych room? I'm at a complete loss at this point. I had thought maybe it was Robert, but he's off looking for what he thinks is his son. Anna's been involved with Emma and Patrick. If it is a Cassidine, what reason would that be for, other than to stir up the 4 pack of Luke, Robert, Anna, Laura (old school peeps), but that makes no sense to me. Then I thought about the Phoenix and maybe it was back in the day when Liz Taylor was on. Now I just read a possibility of suggestion is that it could be Faison who is behind it all, as well as the theory of this being a bad dream and Patrick will wake up and all will be fine. Thoughts?
