Yup...and you can tell thet the trojan is still active if the JW imagines he's gotten free and he instead goes and joins another cult (religion).
I'd classify identification with a cult-ure to be as imprisoning as a cult and an evidence of the trojan as well.
Also any overweening patriotism is evidence of the trojan, as is rooting for a sports team when you have no money on the game.
