The moment Biff entered the living room and locked gazes with Tiffany, there was a very odd moment.
"Biff? Is ... is that you?" Tiffany asked. A rush of memories entered her head. Ones that conflicted greatly with her new persona. She looked down at herself. "What am I wearing?"
"Tiffany?" Biff asked, at the same time. "Why are you dressed as a nun?" He looked down at himself (he was still male where it counted). "What am I wearing?"
Laura came back into the room, looking concerned. "Are you two okay?"
"May we have a moment alone, my child?" Tiffany said. She and Biff, before anyone could say anything else, stepped outside. She looked at him. His hair had gone completely white, and he moved like an old woman, but she could still recognize him.
Tiffany, from Biff's perspective, had fared better. She looked to be in her thirties. "You're...." she said to him.
"I...don't know what is happening. It is like I've become this other person," Biff insisted. "I feel so tired, and my knees hurt..."
"I'm a nun...me," she repeated. "And no one notices anything is wrong. How can they not see it?"
