What will really fry your brain is when you think about how the Romulans are really just Vulcans that broke away during the Time Of Awakening. Romulans are suspicious, distrusting, and secretive...which makes sense when you're surrounded by unstable psychopaths that started a nuclear war. But they aren't as violent or ruthless as Vulcans use to be. So really, Romulans are just the sane stable Vulcans that decided to flee the psychopaths that threatened to kill them all. And now the psychopaths look down their noses at their emotional yet mentally stable cousins.
