Protip: you can come in to Brussels through Amsterdam. Passport control line in AMS is negligible (at least at 5AM, though I'm sure it's not  too bad at other times either), and it's only a 2h train ride straight from the AMS airport to Brussels.

I’m confused is there a passport control for those flying from within EU?

Confused as well, there is no passport control between Belgium and Netherlands
