The official site of Star Wars has posted a second preview of the season 2 premiere featuring once again Darth Vader. Plus a featurette about Vader. Season 2 premiere is only in 3 DAYS ! Are you ready ?
Also according to CNET (who first posted the second preview), Captain Rex will be in the episode, we are not sure about this information since reports from people who saw ‘Siege of Lothal’ at the Celebration in April said Rex wasn’t in the episode (that he would appear in the first regular episode of the season and not in ‘Siege of Lothal’) so I guess it will be a wait and see for this part.
