I prefer to think of this Greedo as Greedo Sr. rather than the dude from ANH. I suppose in the big picture it isn't really that big a deal though. I thought the blue people episode was ok as well, though I couldn't help but think it was kind of suck uppish, with how invincible and brilliant they made Papanoida. I missed last weeks though I don't mind the occasional political intrigue episode, although they have demonstrated in the past that they can do these types of episodes and still maintain a certain level of action/adventure.
On another note, after watching the first two clone centric episodes this season, I must say I'd really like to see some of the final episodes of the series take place during Order 66/the purge. The clones in this show are so much more than the faceless duplicates from the prequels, it'd be really interesting to see order 66 from their point of view. I'm sure some of them weren't that keen on the order, maybe had doubts but followed the order anyway and have to live with that, or maybe some desert. Lots of interesting places they could go with those stories.
