I think this episode could've been very good if there had been an explanation or have some kind of paranormal motive to the man's strange ability. I was hoping to hear something weird when the man was telling Audrey all about the boat and his grandfather but it was just lame and simple. One more thing: if the patients could get violent at some point and they didn't know how long the music effect lasted how was he going to survive all alone with three patients overseas?
Anyway, we can't still judge the show for one episode. First two were very good and all shows have their ups and downs.
There were more inconsistencies but the last scene kind of saves the episode. Audrey is trusting Nathan and he still wonders why she's in Haven. But they both know what they're after and that is a plot I'm eager to follow.
