Vivian Strom is a chef who taught a cooking class attended by Regina and Lydia.
Vivian taught a cooking class that Regina and Lydia took. When she overheard Lydia talking and mistakenly believed she was a lesbian, she told Lydia she'd make her her special project. She coached Lydia through all the steps of preparing the meal, much to the amusement of Regina, who had picked up on what Vivian's intentions were. Vivian invited Lydia over for dinner, saying she'd cook for her. Lydia, thinking it was a friendly invitation, accepted.
Vivian is a chef at Cucina.
