Do you guys have any idea what cloaked David is carrying? I thought it was a cylinder or a canister of something but the way his other hand is gripping part of it like a trigger I thought it might be a type of breach-loading weapons where you open it like a double-barrel, stick the shell in and close it. If you watch that part a few times he seems to snap it closed just as the scene changes.
Am I imagining things or do you see this too?
