Amy opened the door to her dorm room shakily leading the Doctor, Martha, and Rose into it.

Upon entering the room the Doctor accidentally knocked over a stack of papers muttering, "Sorry."

Rose and Martha rolled their eyes as Amy allowed herself to laugh a little bit despite her fear. "No worries there, Doctor. It's my roommate, Sandy's."

The Doctor absently remarked, "How do you humans put up with such a small enclosed place of habitation?" He hated to admit it, but the Doctor was feeling a little claustrophobic in that dorm room. He was also obviously stalling.

Amy sat down and started playing with her clothing while the other women found a seat and the Doctor remained standing. Martha was the closest to Amy and rubbed her back comfortingly. Maybe it was the memories, but Martha felt a unique bond with this woman who she had never met.

Rose asked, "How much of a window have we got?"

Amy replied, "A couple hours. Sandy is in class. Are you sure all the secrecy is needed?"

The Doctor nodded his head and looked on at her darkly. "You have information in your head of things that you should never know about. They're not just dreams, Amy. They're more than that…"

Amy was scared, but was very trusting of the Doctor. She felt like she had known him all her life and her earlier kiss was no fluke. She would say she even loved the Doctor. Wait! Didn't she have a boyfriend? Zach? How could she forget her boyfriend of several years?. The thought scared her as she asked, "What are you going to do?"

"I've done this several times before, so no worries there. My physiology makes me psychic so I'm going to need to read your mind. Not an invasion of privacy. Just helping is all."

Amy looked at Martha who reassured her, "Yea, it's painless. Let me give you some space."

Martha moved away as the Doctor got down on his knees next to the bed. "Lie down and relax." Amy laid down, putting her head on her pillow, closing her eyes, and breathing softly as the Doctor reached over to put his fingers on her temples. "Anything that you don't want me to see just visualize a door and it will keep me out."

With both their eyes closed and Martha and Rose looking on, the Doctor was hit with a wave of memories. Visions clouded his head of familiar adventures he had been on with Martha. Living in the 60's because of the Weeping Angels, himself glowing because he had taken on the essence of a sun, himself and Rose staring in shock as Martha was held at gunpoint, him taking off his tie and showing it to her, traveling the first time he introduced the TARDIS to her, Rose turning around in that lab in the parallel world, him saying "Rose" almost desperately as Martha and the blonde were chained to the wall, and there were more… With each memory it was more than details. The Doctor could feel the feelings, thoughts, and emotions with each one. It was overwhelming to say the least because it really hit home how much he had hurt Martha over the years. Still, there were bigger issues at hand. He was not in Martha's head. He was in Amy's.

The Doctor concentrated harder and was hit with memories from before meeting Martha and saw visions of Martha going to Saint Leonard. Martha was always working. Some of Amy's memories were still visible, but none of them pointed a clue as to what was going on. Deeper…

The Doctor was suddenly hit with the earliest memories. Martha was a little girl being taken care of by her parents looking at the world in awe and confusion, but Amy's were nowhere to be found. They were hidden and it wasn't Amy's doing. The Doctor knew what was happening here and he had to make it right!

As he cut his psychic connection he was hit with a new memory of Martha strapped to a chair against her will and a shadowy figure with a male voice saying proudly, "Rose Tyler is dead." It was a memory to come from Martha's future and the thought completely scared him as he opened his eyes and stood up.

Rose was the first thing the Doctor saw as he opened his eyes. Rose, who according to the future memory, was going to be dead. He put on a nonchalant face as she asked, "What did you find, Doctor?"

The Doctor ignored her and instead asked Amy fearing the answer that he also expected, "Amy, what are the names of your parents?"

Amy opened her eyes knowing the Doctor was done and smiled at the thought. "Francine and Clive."

Martha's jaw dropped to the floor as the Doctor added, "Earliest memory?"

Amy again smiled. Thinking about her past was always comforting to her as she recalled, "I remember a time when I was five when mum had just bought me this doll, or Barbie is what it was called. She handed it to me wearing this white coat and said, 'Here, dear.' Being as young as I was I had to comment, 'She's black.' What my mum said next inspired me for many years to come. "And so are you, so there's no reason you can't be her."

Martha couldn't believe it. That was her memory and Amy wasn't even black! "No…" She then stared at the Doctor wanting an explanation that made even the least bit of sense. That could not have been a memory from Amy's past and there had to be a reason behind it all.

The Doctor darkly commented, "It's taking you over, Amy. Memory by memory, it's replacing yours with Martha's. You've lost your childhood and your already starting to lose your recent years. I'm so sorry this has happened to you."

Rose asked, "Is there anything we can do?"

The Doctor shook his head at her. "Theirs nothing, I can do. Martha, only you can save her."

Martha looked at him. "What… what can I possibly do?"

"I can't help you do it. Believe me, Martha Jones, I want to more than anything, but I can't even be in the room."

Martha was completely shocked. "Why? Doctor, if I need to do something just give me a hint! Anything at all and I'll do it!"

The Doctor looked at Rose. "Rose, we need to leave."

"But, Amy, Doctor! Are we really going to leave her like this!"

"You and me, yes. Martha, no. Martha's going to save her and we can't intercede."

"You're not making any sense!"

"Leave them, Rose. I know what I'm doing and we really need to go back to the TARDIS. We can't interfere or it won't work."

She stood up and stared him down saying, "Are you sure, Doctor?" He simply forced a reassuringly smile and nodded. Rose half smiled back. "OK, then."

The Doctor leaned over to Martha and offered, "While you figure it out, why not talk to her?"

The Doctor left with Rose following as they opened and shut the door behind them. They were going to the TARDIS and Martha was left alone with Amy wondering what in the world she could possibly do to save the day.

Martha silently asked herself, "Doctor, what is it that I'm supposed to do?"
