Excellent write up.
A bit of context for the choke on your aspirations line: Vader hates politics and the political scheming among the Imperial ranks (Death Star/Tarkin Initiatives projects has exacerbated this). Vader holds no rank or formal position within the Empire. The political, ambitious officers of the Empire are beneath him and the Dark Side/Force. Krennick would have been executed on the spot if he wasn't a Director.
That still doesn't change the fact it's a fucking awful pun, though.
