Yeah, no, I definitely agree with Kylo’s “lack of faith” in his troops, as you say. I guess I just don’t really see this specific hangar as being super-duper important to the story, so I’m not as concerned with doing so much setup for it. After all, Rey spends all of thirty seconds in there before slipping away through an access tunnel. All that really matters is that they don’t know where she is.
That said, I fully trust your artistic vision, Nev, and I’m sure it’ll all come together beautifully!
