Anyone else catch the reference to the types of Romulans? Above are Picards "Housekeepers" who are ex Tal Shiar operatives. Picard saved themed, while on an away mission(takes place in the new Picard comic) They fell in love while on assignment together, which is forbidden by the Tal Shiar, and so the helped Picard, and he took them in.
Laris, the female, is the most common type of Romulan we see, and are physically very similar to Vulcans(Romulans, Vulcan, and several other species, are distantly related)
Zhaban, the Male, is referred to as a Northern. They are generally a little larger, and have the pronounced brow ridge, The Males are often Bald.
Elnor, male, are very similar, but they are usually long and sleek, kinda Elf like. His people are far more spiritual, than most Romulans.
You also have the Remans, who have been isolated on the Dark Moon of Remus. They have telepathic abilities, similar to Vulcans. They have been used as slaves labor for Romulus, and have had several civil wars with Romulans.
