I've been saying Tarkin should show up for a while now. (Why should Wulf Yalaren be the only future Imperial lackey we see?) And I doubt anybody is clamoring for more episodes about Baron Papanoida and his family. ;)

This is the only guy besides the Emperor to order Vader around, and it will be interesting to see how he gets to that position of power. And find out if he and Anakin have any sort of a working relationship before ROTS.

If none of the other characters comment on the "foul stench", I will be very surprised!
