It seems to me that in the novel Sphere by Michael Crichton, Beth (the woman that also had the power) didn't forget the whole thing at the end.
They found a mummified woman in a hibernation chamber that looks like Beth (page 250):
"She's pretty good-looking," Harry said, peering through the glass. "Boy, the reporters would go crazy with this, wouldn't they? Sexy woman from the future found nude and mummified. Film at eleven."
"She's tall, too," Norman said. "She must be over six feet."
"An Amazon woman," Harry said. "With great tits."
"All right," Beth said.
"What's wrong-offended on her behalf?" Harry said.
"I don't think there's any need for comments of that kind."
"Actually, Beth," Harry said, "she looks a little like you."
Also Beth apparently would make use of the power to make herself look very attractive, what brings me to what happenes in the end:
He glanced back at Beth and Harry. They both looked tired. Beth stared into space, preoccupied with her own thoughts. But her face was serene; despite the hardships of their time underwater, Norman thought she looked almost beautiful.
"You know, Beth," he said, "you look lovely."
Beth did not seem to hear, but then she turned toward him slowly. "Why, thank you, Norman," she said.
And she smiled.
