Quite frankly, the characters of DS, not the supernatural elements, are why I enjoy the show, and a good deal of that is the friendship and jealousy between Barnabas and Julia. It's quite clear with Julia, from the minor things (her "Here we go again!" looks when Barnabas finds Josette in 1897 and finds Roxanne in 1970PT, as well as her "What else have you had, Barnabas?" in relation to Megan) to the major (her outburst over Angelique, and did it look to anyone else like [spoiler]she shoved Roxanne out of the PT room at the end of 1970PT?[/spoiler]). It always provided a good amount of entertainment from those two. Of course, the fact that Barnabas was thoroughly unwilling to let Julia get swept away by some other vampire is an interesting parallel to that.
