Based on the character of the same name from Doctor Who (1979-81)
Why did Romana ii come to my village before Romana i, you may ask.
The answer is simple.
Why not?
They're Time Lords, why would anything time related make sense with them?
"You know what I don't understand?"
"I expect so." -Romana ii
"Shall we take the lift or fly?"
'Lady Romanadvoratrelundar, graduate of the Academy of Time Lords (triple first), favoured scion of the noble House of Heartshaven, and the terror of the trans-temporal debating society, stared at the Doctor and said: "Huh?"'- City of Death novelisation
Also, Romana is short for Romanadvoratrelundar. That's an important detail to add. She goes by Romana for efficiency but her full name is Romanadvoratrelundar. When Scarfy first met her all he said was "I'm so sorry about that"
She and scarfy are just really good friends who happen to have children because I wanted a null so they're platonically parents. Some people ship them, and I can see why but I don't personally but hey if you want to see them as a romantic couple I won't stop you but my interpretation is that they're platonic.
