The "Is Door Closed?" question is treated as though it's a Magenta Line. The Door Is Counted As A Wall from the Rule Book and Insert.
Since It Is Setup, The Door Cannot Open, So It Is Considered A Magenta-Line'd Wall.
Characters must spend an activation to make a door open,
so, Vader can designate that door as open afterwards.
That resolves before the first 'activation' of that turn.

I know they make many, many other awesome jokes since but,
seeing JEJ riff on that was hilarious.

I'm your bosses's boss."
