[Maritime Q-Scout]

So why did the undercover agent who spent years moving up the ranks infiltrating Star Fleet, becoming head of security, just leave and command an armada of Romulan ships?

Like how does that work exactly?

Also Riker is on Active Reserve and suddenly is captain of the Federation's Flag Ship leading a massive amount of battleships to defend against the Romulans?

What the hell? Like how does HR work? Line of command? How does any of that make sense?

The weird things I pick apart. Magic do anything tool? Meh, but I need an explanation of human resources in Star Trek and how retirees and secret agents get to command battles.
