Morriss and Sergei

Character
Morriss and Sergei Morrisergeivich were twins who rented a building they ran a book store out of, from Grandma-ma's father back in Russia. Sales had been plummeting and they could not pay rent when Sophia came to collect it. Sophia however was always understanding.

Because all of the people Grandma-ma knew in Russia are portrayed by the main cast in her flashback, it is possible that Morriss and Sergei were not actually conjoined twins.
