Before Robau left the ship, he basically gave George a field promotion to Captain. Is or was that Starfleet policy? I may be wrong, but I don't recall that ever having been done before. The Captain usually just puts the next ranking officer in charge to hold down the fort until he gets back. Was it done because Robau knew with badass precision that he wouldn't be coming back? Was it to add dramatic effect? Was it to show how in this universe promotions are thrown around like rice at a wedding? For all I know, the answer may be somewhere above, but I certainly wouldn't mind the opinions of someone a little bit more knowledgable in this particular department of Treklore.
Come what may, rest in peace Captain Kirk Senior.
