It was surprising to see Barnabas get something right for once. I remember all those weeks when he and Julia couldn't grasp the connection between him and Adam ("Julia...Julia..."), but today he figured out the connection between Petofi and Jamison in the wink of an eye.
Jamison's life was dependent on Petofi's, and David's life is dependent on Quentin's. It's a pity that Barnabas couldn't go back to 1797 - to the time when Petofi's hand was cut off - and find another vital connection to add to the pile. Granted, Petofi's hand was cut off in the Forest of Ozhdun (out come the fake trees and the green mat) but I'm sure the writers could have managed to make it all contingent on something that happened at Collinwood.
Aristede mentioned that the hand had touched the Sphinx. Was that when it acquired its power? And why do I keep wondering what part of the Sphinx the hand touched?
It was very poignant when Quentin showed how much he loved Jamison. Quentin was willing Jamison to live. Yes, indeed, Quentin would have been a great father to his son.
I don't think we can assume that Quentin would have been a good father. Quentin's too easily distracted. And anyway, even though Quentin loved Jamison (it's interesting, by the way, that he forgets about Beth, and even says that Jamison's the only one he ever
cared about, let alone loved) he still put him through some nasty Satanic ceremonies.
