In the grand tradition of Savage Oppress and Elan Sleazebaggano, it's a new Star Wars character whose named describes who he is exactly. But hey, colorblind casting! David Oyelowo proves that race is no issue to excelling in the Empire - only mastery of a sinister English accent matters.
If he ends up straight-up murdering Freddie Prinze Jr.'s character at the end of the series, I think I'd be very satisfied with that. Then again, maybe Freddie will surprise me like Ahsoka.
