I see many guesses for Elvira, and one for Emma Peel. She’s actually not any specific character (although Mrs Peel comes closer in my mind.)
Basically, Rita is still paranoid about Maxine. Although we haven’t seen her these last few days, we can assume that Maxine has been showing up with the same looks each day, hence Rita abandoning them.
