Well, I think it’s even more funnier that Krennic traveled to another planet for who knows how many hours to have a one minute discussion with Vader, ha.
Vader doesn’t have a phone in his retreat.
I just meant that there must’ve been an easier way to deliver a one sentence message, even for Vader who has to suit up for this “meeting”. I don’t mind it, I like the scene, I just find it a little funny if you think about it but I try not to.
