Ever since they introduced the humen form replicators I've been waiting for them to bringt Fifth back. They really did him unjustice but I was glad to see how his character still had some humantity left in him. Hopefully he will be back once again to kick ass.
The Asgards also made a great comeback in this episode, Thor classy as always and the interaction betwean him and Jack funny. Jack might tone it down a little bit though, sometimes I get the feeling like he's not taking his job seriously. Anyone else feel that way? Finally, naming the asgard ship The Daniel Jackson... great!
