How do we know Cosimas last name? I don't recall it being mentioned in the show, I only stumbled upon it when I was researching OB.

In season 1 when Delphine was looking through Cosima's papers when Cosima went out to get Eskimo pies we saw Cosima's last name written on Cosima's notes. Also in Season 4 when Cosima was at Brightborn Susan Duncan mentions Cosima's last name to Evie Cho.
