Understandable, but in Hal’s words from last page: “I totally agree that such dialogue would be great to have there, but I don’t think the existing material to work with yield something worthy of inclusion.”
I don’t know if it would be good to imply that they’ve been talking by seemingly beginning in the middle of a conversation because either way the left out conversation is still just in our “headcanon” and audiences watching wouldn’t necessarily come to the conclusion that they had that exact conversation just by leaving out “Supreme Leader”. And the imagined left out conversation can still make sense with how it’s presented now.
Good point. Maybe TLJ will offer some dialog to improve this scene in a potential V3, but for now you’re probably right in leaving it as is.
Oh, and the slowed down shots are the pilot reactions when Starkiller fires. One of Poe and one from another pilot whose name I can’t remember. They’re both taken from the “There’s a brand new hole in that oscillator” scene IIRC.
