I haven't had the chance to watch Rebels (I'm not in the US), and I'm trying to see if the page where I watch American TV has it (haven't checked). But it sounds like an interesting show, I'm glad to hear about Kanan, it sounds like they are exploring the possibilities and the roads not taken when the Order was in is heyday.

In all frankness I never quite understood the Order's need to forbid attachment. Yes, it's a double sided sword and some Jedi could have had the chance of falling --like Qui Gon after Tahl's death--, but overall, it's also a very powerful motivator for good.
