The Master awoke to the smell of bacon and the sound of vomiting. "Well, that's lovely." He thought. He put the bedding away back in the closet and went to check on the hungover man that was inevitably throwing up whatever was left in that skinny body of his.
"Alright, mate?" The Master asked while passing by. John was too weak to give a response, so the Master walked into the restroom and laid a hand on his shoulder.
"Come on. You need to eat something." The Master walked John over to the kitchen to see Rose still in her nightgown, trying to prepare breakfast for her family.
"Oh, that's a surprise. Didn't think I'd be seeing you here so early in the morning." Rose said, sarcasm dripping from her mouth as she noticed the Master. He set John down at the table and walked over to her.
"Look, I don't want to create this rift between you and him. Obviously the Doctor left him with you for a reason. I can't even pretend to understand the reason; I never understood what made the Doctor so fascinated with you humans. But if he left this wonderful man in your care…he obviously loves you very much. He wants what is best for you, and that can't be travelling with him forever. He gave you a piece of him that is solely yours, one that you don't have to share with anyone else. He," the Master said, gesturing to John, "has no one else. So, of course he's going to be upset when he can't talk to you or he feels like your relationship is on thin ice. You're the only one in his life. You're his world. Now please, please, talk to each other and sort this out. I'll just leave. You know where to find me." The Master left the flat and went back to his TARDIS.
The Master got himself cleaned up and changed and sat at the console contemplating the past day's events. He heard a knock at the door.
"Hey, we made up…I just wanted to let you know. Can I come in?" he heard a manly voice say from outside the door. "Sure, go ahead." The Master replied. "Where's Rose?" he asked, as he noticed the lack of blonde coming in the door in front of him. "She went back to the flat to talk to her mum. We came to check on the TARDIS and it's finally finished!" John grinned, and went to hug the Master.
"That's great." He patted John on the back. "It looks like we'll both be off soon, because my TARDIS seems to be gearing up quite nicely for another parallel universe travel."
"But you can't do that. Not without causing serious damage to something. Your TARDIS, or the planet, or the universe, or all universes combined…that's what happened the last time…that's how Rose-"
"Did someone say my name?" Rose interrupted. "You boys better be saying nice things about me."
"We are." John scooped her up and gave her a kiss. "Did you talk to her?"
"Nah, she wasn't there. I assume she took David and Tony shopping because no one is home. But that shouldn't stop us from our first trip!" Rose exclaimed.
"I don't know…I don't exactly feel comfortable just whisking you away again after we've been so…settled… for this long." John replied.
"Exactly that. We have just "settled." All those stars and planets, the whole universe…it's out there waiting for us, untouched. You have his memories…how could you possibly settle?" Rose questioned.
"I would just feel better if-" Rose interrupted again. "Come on just one trip! We'll be back soon enough! …Hopefully." She looked at the Master. "Hey, do you want to come with us?"
The Master looked at John, and John back at the Master, and he stuttered out, "Well, I, uh, I mean…possibly?" He finally settled on a response.
"Oh no, Master, you were just telling me that you had your own travels to get to…I wouldn't want to hinder your plans." John said to the Master, who gave a confused look back at him.
"Really? What travel plans? We can go together, and save the TARDIS fuel…but if you don't mind, I'd like to take our TARDIS because it is a momentous occasion. What do you say?" She posed the question to both John and the Master.
"Well, are you going to tell her that you're travelling to a parallel world, or should I? John replied.
She looked at the Master. "…because you want to find the Doctor. I get it." Rose jumped in. "And I can't really blame you because… I have done the same." John went to hold her hand. She tucked her head into his chest and listened to his sole heart beat, the one that was solely for her. "We don't have to go right now, but to get that back again…I want nothing else in the world." She looked up at John with loving eyes.
John looked down at her after realizing that she was talking to him and not the Master, and the tension in his bones eased up.
"Would you look at the lovely couple?" The Master spoke. "Not that I mind this-" he gestured to the lovers, "-I actually would like to get this show on the road, so… I guess this is where we say our goodbyes and-"
"Don't leave yet!" Rose interrupted for a third time, breaking away from John. "At least stay for one more meal, and a proper goodbye? Don't you agree?" She turned to John.
John looked at the Master and smiled. He held out his hand and said "Come with us." The Master looked at the pair then reluctantly took John's hand.
