"Madam," Rachel said. "It's a pleasure to meet you."
Behind Rachel, Biff heard Marty giggle.
"Isn't she such a dreamboat?" He asked Biff.
"Umm, sure," Biff said. "But, shouldn't we be downstairs warming up?" He said, dutifully.
Rachel looked at him. "Perhaps we should. I feel rather...warmed up already. But you have just arrived, so things should get much...more warm," she said, looking at Biff, who blushed again.
They headed back downstairs.
