Foreman wished he could carry around a dictionary the same way Brook did. With a dictionary in his hands, he wouldn't have to worry about the possibility of running out of words to say. Instead, he would find something to allow him to speak the way he wished to. But, of course, he had no dictionary nor any way to describe his thoughts through proper words.

He wished he could allow himself to get lost within the TARDIS hallways, but she would most likely end up bringing him right back to the control room now matter where he headed off to. It would be absolutely useless to think about getting lost. If the TARDIS wanted you to find your way, then you would most certainly end up at your destination.

And, of course, Foreman assumed that the TARDIS didn't care much for him to begin with. Perhaps he had married the Child of the TARDIS squared and fathered her child, but that didn't change the fact that he'd nearly ended up destroying the TARDIS during his fits in the past. With the idea he was pursuing, however, he wouldn't have to worry about what the TARDIS might think of him.

But as he stepped into the control room, he found all of these thoughts disappating. In a split second all had become too quiet for him - all that he could hear properly was the sound of his own breathing. Both the Doctor and Susan stared at him, wondering what he was up to.

He'd planned his words time and time again, as he kept throwing them out when he realised they wouldn't display what he wished to say. He stood for a moment, trying to throw together words until he finally decided to just speak.

"I...I'm leaving," Foreman said. "I can't stay here any longer. The TARDIS has been good to me, yes, but I can't stay here for much longer. It isn't going to work out well...well, let's be honest. It hasn't worked out well."

The only response from the rest of the TARDIS was the light hum of near silence. No one knew quite what to say, as if they were unsure if they'd actually heard Foreman correctly or not. Sensing this reaction, Foreman decided that he needed to say it out loud again despite how difficult it been for him to speak in the first place.

"I have to leave the TARDIS behind. It seems absurd to say such a thing out loud, but I've determined that it will be best for me if I do such a thing. It will best for all of us."

"Father, no," Susan said, reaching out to take his arm within her hands. "Father. I need you to stay with me. We were seperated for so many years, why can't we be together now?"

"The TARDIS is not my home. Gallifrey is not my home. What I've realised is that I've been looking for home for so long...and home is Brook's planet."

Foreman took a deep breath in, attempting to determine what else he could say. How else was he supposed to explain that going to Gallifrey simply felt wrong to him at this point in time? It wasn't even the "home" part that bothered him so deeply any longer...he couldn't stand the thought of returning.

But he needed to go back to the place which had nurtured him, the place where he had built a new life and gained a family. Perhaps that place would be empty when he returned, but empty was far better than going to Gallifrey.

"I need to go back to that home. I lost that place so long ago, and I can no longer bear to stay away from it. This thought never crossed my mind for the greatest time, and now that it's lodged myself within my mind I know I can't get it out. I have to leave, and I have to leave soon."

Neither the Doctor nor Susan made any sort of reply at first. The two just continued staring at him, both with surprise written across their features. But then Susan couldn't wait to speak any longer.

"Aren't you going to miss me, Father?"

"That is a silly question to ask, Susan," Foreman said, shaking his head. "Of course I'm going to miss you. There was never a time when I wasn't going to miss you. But that doesn't mean that I can stay here any longer."

"But if you're going to miss me, then you shouldn't have to leave," Susan said, allowing her lips to form a small pout. Foreman couldn't stand looking at her acting in such a manner. She might have hundreds of years to hear name, but when she did such a thing she almost looked like she was a tiny four year old rushing around.

"I have to leave whether I'll miss you or not. I'll miss you more than I can say, but at least I won't be separated from you permanently. This will not be our last time together, I'm certain."

Susan, although she was far from content with this answer, remained silent for a few moments longer. She needed to determine her response, figure out something that could get her father's mind to swing in the way she wanted it to. He was barely making sense to her. Since she didn't want to make sense of it all, she couldn't comprehend any of it.

But if she was going to manage to convince her father to stay with her, she was going to need to keep some rather emotional words with her. She needed to convince him within a matter of sentences.

"Father, I don't want you to leave me behind here because I am going to miss you," Susan said. "It's not just that you'll miss me, it's because I am going to miss you so much. I didn't know how much I missed having a true parent until I had you. I can't remember anything from when I was tiny, but..."

"Susan. I am sorry. I have already made my decision on what I must do, and I must go. There is nothing more that I can say to you now. I must go or I will regret it forever."

"How can you be certain of that?"

"I can't be certain of anything, and that's all that is certain," Foreman said, giving a slight nod in his daughter's direction. "I know that it sounds maddening, and it is. I don't want to this completely. I just know that it is the best thing for me to do at this point in time."

"How can you know? You never seem to just know most things, Father. You have to think about them for a long time, otherwise-"

"Susan," Foreman said, cutting her off. "I don't think you're thinking through your words any longer. And I'm sorry to say it, but nothing you say will end up getting you anywhere further. I can't stay, Susan. That is the way things have to be, no matter what you think of it."

Susan looked to be on the verge of tears, but Foreman knew he couldn't prevent them from falling if she'd already made up her mind to cry.

"Grandfather, can't you do something to prevent him from leaving?" Susan said, whipping around to face the Doctor. "Can't you convince him to stay?"

"I barely convinced him to stay when he first came in the TARDIS," the Doctor said. "He seems to be thoroughly convinced of what he must do, and therefore it seems impossible that I can change his mind about any of it."

"But you have to be able to do something!" Susan exclaimed. "You can't let him just walk away from all of this as if none of it ever happened! You have to care!"

"I do care, Susan," the Doctor said. "I care very much. But even if I care, that doesn't mean I am desperate for Foreman to stay. It is useless to tie him up here if he doesn't want to be here. He was always meant to leave the TARDIS, I think, and now he has chosen to leave."

"Grandfather! You can't be serious about all of this. You have to...you have to..." Susan kept saying.

Foreman, though he knew he should be upset about how his daughter was reacting, he couldn't help but feel somewhat relieved. Susan didn't hate him. Susan loved him as much as any daughter should love their father, and he could not be more pleased. She truly wanted him to stay with her in the TARDIS.

And with that thought in mind, Foreman became entirely certain he had to leave.

"Susan," Foreman said, interrupting the conversation which had continued with his daughter and the Doctor. "I am sorry you feel so upset over my choice. But I have indeed made this choice, and that means I must leave."

Hearing the firmness within her father's voice, Susan fell silent. There was no convincing him, no matter how much she cried. Her tears would do nothing more than drip to the floor. Susan would just have to find ways to accept what was happening, as there was no way for her to stop any of it. No, this was how all was to turn out.

"Thank you, Doctor."

"Thank you?" the Doctor said. "I never thought I would hear those words from you, directed to me."

"Perhaps it's because I never realised I had things to say to you to begin with. I understand what is happening now, and that means I can thank you for it all."

"Well then, you're welcome," the Doctor said. "I can't say I don't appreciate your thanks because I do. I hoped that my words would get to you in the end, and it appears that they have. Sometimes I wished I had not waited so long to speak to you bluntly. It has done good, I think."

"Certainly," Foreman replied. "I know that you wouldn't have told me if things weren't amiss, though."

"Never mind that," the Doctor said. "I got the information to you eventually, and that is what is important at the end of it all."

"You told me everything that I needed to know - and perhaps a bit more."

"And to think that you kept telling me that I wasn't telling you anything that you needed to know," the Doctor replied.

Foreman shook his head and then said, "Well, I didn't know what I needed. It wasn't until recently when I realised what I needed to do. I've figured it out, and that is what is important. I couldn't have done that without-"

"Foreman, no need to thank me endlessly," the Doctor interrupted. "Your first thanks lasts for a lot longer. Susan and I don't need to hear it."

"Oh, well then," Foreman said. He knew the Doctor's sudden affability would disappear just as rapidly as it appeared. "Then I will not thank you again. I'll thank you some other time."

"Assuming that you'll see me again," the Doctor said. "I assume you will, one day."

"Will you take me back to Brook's planet, Doctor?"

"If you are certain that is where you wish to go. I know there are thousands of memories lodged within every detail of that place, memories that you might not want to dig back up."

"There are memories everywhere which I might not want to dig up again, Doctor," Foreman replied. "I wouldn't just decide to go on a whim - well, not after all that's happened. I assure you, I have thought this through. I think that going back to the place that is my true home will be far better for me than searching for a home I abandoned long ago."

"I believe that you have thought about it, then," the Doctor said. "I suppose I'll be getting us to Brook's planet now. Didn't think I would ever have to go back there...but things never go exactly as one plans."

As Susan listened to these words, she found herself desperate to clutch out for her father again. She needed him to stay, no matter what he thought he needed to do. No, she required that he was going to stay by her side in the TARDIS.

"Father, I..." Susan began, unsure of what to say.

"What is it, Susan?"

There was stagnant moment of absolute silence while Susan did her best to determine what she could say in order to get him to stay. She had already given up once, but this time she would have to persist even further.

"I just can't believe you're leaving me and all of this behind. Don't you love traveling in the TARDIS? I know you think she doesn't like you, but-"

"Susan. I know you want me to stay, and for that I want to stay as well. But you must understand that I cannot. My mind has been made, and so I must go. Nothing you say will manage to get me to say. I know that's dreadful, but it is the truth."

"But...Father, I just got used to having someone from my immediate family with me. I finally had a father because of you."

"You won't stop having a father when I'm gone. And, this time, you'll be able to remember me. You'll be able to remember it all. All the horrible things I did, how I kept my identity from you...how you came to know me as your father. Susan, that will all still be there. Cherish that you even have those memories at all."

Susan now was at more or less of a loss for words. Her meaning had been lost in her outcry until everything just hit a wall. Her father looked so proud, so happy...he looked as happy as she'd seen him. It wasn't something she had expected. No, she had just thought he might be somewhat apprehensive, feel something more...

But, instead, Foreman just stood there and smiled. He was proud of himself for making his decision, for finding the path that he was meant to go down. This was what he was meant to do, after all.

"Are you sure, Father?" Susan asked. It was clear that she was poised to ask thousands of questions just to convince him to stay. "Are you absolutely certain that you must leave?"

"Certain?" Foreman echoed. "I suppose I am certain. I don't have much of anything else I can be."

"Then I suppose we'll be saying our goodbyes soon," Susan said, releasing a sigh. Hearing that her father was certain ended up being the final straw - no matter what she said, he would not listen. He was too far gone.

"Goodbye, yes," Foreman said. "But we will meet again, Susan. I will be on Brook's planet for the rest of my days. Perhaps when you two find Gallifrey you can come and seek me out. I will await you for as long as time lasts."
