Heartwarming / A Thin Veneer

• One of the flash-forwards to future events has a very subtle bit of Fridge Heartwarming. A scene onboard a Federation starship has a Narn and a Centauri as members of its bridge crew. The Federation was able to bring in two races that have been at each others' throats for centuries after the latter enslaved the former. And this was passed off as no big deal.
• President Elizabeth Levy has only just met the Federation and is adjusting to the idea of human/alien relationships, but where William Clark dismisses Vulcans as too different for him to understand, Levy only needs to talk briefly with Sarek to recognise that he truly loves his human wife.
