Continuity Snarl
Okay I love this show, but in light of the most recent episode something bugs me. In the first episode Jason was in the quest after his father with the implication he had known him at one point then he was vanished, later in the same episode it was stated he was taken to the other world when he was an infant.
As such it followed with the idea he had never truely met his father, which explains why he couldn't recognise Aeson (by voice if not apperance) when he met him. But according to this episode he actually grew up with his father, or at least was old enough before he left to ask him about his mother, so which is it? And if its this one, then how come he couldn't recognise his father when he met him?
