There is a bit of mature content in this story. Also keep in mind that I'm making Eva a little more crazy than she was on the show. Her presence is to show just how psychotic and dark her thinking is.
Hope you enjoy this!

Two days later Eva walked about the island. The Skipper and Gilligan were working on the boat to prepare it for their journey to Hawaii. The Skipper wanted to make sure it was in tip top condition before the set off. Eva looked at the different plants and flowers in the jungle. She stopped when she heard was sounded like female laughter.

Peeking through the banana leaves, she witnessed the Professor and Ginger engaged in a kiss. Eva observed the Professor's behavior with Ginger. He seemed to simply adore the red headed movie star. Always kissing her and holding her close. Whispering things in her ear that made her smile and giggle. There was also the way he looked at her. Like she was the most beautiful specimen on Earth and he was proud to claim her as his.

The more she had observed the pair together the more obsessed she became with them. The passion and love between them. It was something she wanted for herself. Why couldn't she have that? Why couldn't the Professor love her? She had Ginger's looks. If only she could be Ginger…A thought occurred to her. Why couldn't she be Ginger?
She looked just like her. Sounded a bit like her. Certainly she could master her walk and other idiosyncrasies.
The Professor was already crazy about Ginger so she wouldn't have to bother trying to get him to fall in love with her. He already would be.

Ginger lead a glamorous and glitzy life in Hollywood. She was beloved by millions. Why couldn't she, Eva, experience that? Imagine walking the red carpet and having photographers flash their cameras. The reporter vying for her attention. The adoration of the fans. It was a dream. A dream she wanted. And was going to have.

First she had take care of Ginger. Get her out of the way so she could step in and take her place. There were plenty of caves on the island. She could keep her tied up in one of them. No one would know the difference. She was convinced of it. Once the Skipper and Gilligan had the boat all fixed up…they all would set sail for Hawaii. All but Ginger. Eva smiled to herself. It was the perfect plan.

Camp

Mary Ann set a plate of fish in front of everyone and they dug in.

Eva watched as Ginger sat in her usual spot next to the Professor. Her eyes observed Ginger placing a kiss on his lips and whispering something Eva was sure was inappropriate as the Professor smiled at her returning her kiss.

Throughout the dinner, Eva kept her eyes on Ginger focusing in on every little detail. The way she held her fork. The amount of times she chewed her food. There was also the way Ginger placed her hand on the Professor's knee and would sneak in a smile or a kiss. She also kept tract of how the Professor responded to her. Softly telling her how beautiful she was and other things that Eva couldn't quite make out. Nuzzling her neck and putting his arm around her kissing the top of her head.

The meal came to an end. Mary Ann cleared the table with the help of Gilligan.

Ginger took the Professor's hand and they walked to the lagoon. Eva made an excuse saying she wanted to lie down for awhile. She followed the couple out to the lagoon. If she was going to take the place of Ginger, she had to do it right. Make sure no one could tell the difference. Not even the Professor. Eva was convinced she could do it. She was more than up to the challenge.

"Professor Hinkley…" giggled Ginger as she was backed up against a tree. "What are you up to?" She asked as she felt his lips on the soft skin of her neck.

"I'm in the mood for dessert.." was his reply as his arms went around her slender waist.

Ginger grinned. "You had dessert…Mary Ann made a banana cream pie…"

"I like your dessert better…" He replied kissing her moist lips.

"Mmmmmm" Ginger groaned loving the feel his kiss.

His hands went up and pulled down the straps of her white dress to reveal her ample breasts.

Ginger smiled as his lips touched the bare skin of her chest. "Roy…Oh yess…"
She felt his tongue against her hard nipple and she could hardly contain the excitement she was feeling. "Oh God…" She said pressing him closer to her writing body.

Her hands found his buckle and undid it. She slid off the belt and threw it to the grown. Next her fingers unzipped him and she gasped as he entered her.

"Aaahh…yess…oh yess.' She cried clutching to him tightly.

Eva's eyes were glued on the lovers. She mentally checked off all of Ginger's mannerisms in her head. Taking care of note the pitch and the tone of Ginger's cries. The fact that she was watching the two engaged in a heated love making session didn't even phase her mind. All Eva was focused on was doing what she needed to become Ginger Grant. To do that, she needed to know everything. Even the way she made love.

Ginger went lax against the tree as soft kisses were placed on her neck. It wasn't long before she was swept back into the Professor's arms and they sunk down to the warm sand holding each other tight.

Eva kept watching as Ginger climbed on top of the Professor kissing his lips. Her hands deftly unbuttoning his shirt and running along his toned body. She bent down and kissed his torso while the Professor's ran his fingers through her hair. Her mouth went back to his lips and kissed him with intense passion. Her hands went through his sandy hair as his arms were now wrapped around her.

"Oh Professor.." Ginger said in her breathy voice. "Professor…I love you so…You just do something to me…" She went back and kissed his lips again.

Eva recorded it in her memory bank. Nothing was going to get by her. Satisfied she knew Ginger's lovemaking routine, she left the spot and walked to the girls' hut. She went inside glad that Mary Ann was not there. She smiled sitting at Ginger's vanity table.

Eva picked up the mirror smiling at her reflection. She was so beautiful. She touched her cheek. The plain and ugly Eva was no more. Soon she would be the new Ginger Grant. Loved by all. She pictured it all in her mind. It was a dream she was determined to make come true.

Lagoon

"My dear Ginger you are the most amazing woman I've ever known." The Professor said holding her against his body as they gazed out at the water.

"That's the sweetest thing anyone ever said to me." She replied.

"You mean to tell me no one ever said that to you before?" questioned the Professor.

"Well they did but they didn't mean it. At least I don't think they did." She replied. "People will tell you anything in Hollywood."

"Oh? How do you know when a person is being sincere?"

"You learn." Ginger said snuggling closer to him.

"You miss that life don't you?"

Ginger nodded. "I do. Very much. I love acting. I always have. Ever since I was a little girl. I felt like I was born to be on the stage or on the big screen."

The Professor gently caressed her arm. "You think…there would be any room in that life for me..?"

Ginger smiled and turned to him. "Of course." She said. "I would love nothing more than to be seen on your arm."
"What about Cary Grant? Gregory Peck? Rock Hudson?"

Ginger placed a kiss on his lips. "They are boring and dull compared to you."

"You are a beautiful liar you know that." The Professor smiled.

"Thank you." She said leaning in and deepening the kiss.

Later

The Professor walked Ginger back to her hut and kissed her goodnight. The redheaded starlet walked in floating on air.

Mary Ann smiled as she saw her friend. "Nice night?" She asked.

"Wonderful." Ginger replied in a dreamy voice. "He is so wonderful." She sunk down on her bed and sighed. "So so wonderful."

Eva, who was pretending to be asleep, was listening. Won't be long before that's me. She thought to herself. Soon I'll be in the Professor's arms. I'll be the new and improved Ginger Grant. Good riddance to the old Ginger.
