A/N: Well, here we are. This is turning into a full fledged fic. How in the world did that happen? Please R&R

Martha Jones had had a good day. Mum and Dad were getting along well with Tom, something that wasn't always easy. The four of them had gone out to lunch together, working on wedding plans. Martha was still trying to convince her mum that while money wasn't much of an issue with her UNIT pension, they still wanted to have a small wedding with only close friends and family.

"Martha?" Tom called from the kitchen, staring the window.

"Yeah?" Martha replied, coming to stand beside him, trying to see what caught his attention. Donna Noble was pacing the sidewalk across the street, muttering to herself as she looked at all the houses in confusion. "Oh, it's Donna!"

"You know her, then?" Tom asked, looking at Martha's surprised smile with fond amusement.

"She's a friend," Martha explained, already reaching for her sweater to guard against the cool night air.

"Oh, that kind of friend. She doesn't look polished enough for UNIT. I could see her getting along with your Jack, though, is she one of his?" Tom asked good naturedly, long used to Martha's profession.

"One of the Doctor's actually," Martha replied, causing Tom to glance back at Donna with raised eyebrows. He knew all about the Doctor and wanted to meet him someday. After all, they might never have met if it weren't for the Doctor.

"Donna?" Martha called after opening the door. Light spilled onto the road and Martha blinked, trying to focus on Donna's shape as her eyes adjusted to the dark.

"I am on the right street!" Donna said, walking quickly to the stoop. "I really couldn't tell. I'm going off his memories, you know. They're disturbingly clear and frustratingly vague at the same time."

"Come inside," Martha offered, holding open the door. She saw Donna's slightly harried expression and frowned. "Something's wrong."

It wasn't a question, and Donna knew it. "Yeah, long story. What I really need is the Doctor's phone number. Or, your old mobile's actually. And, sorry to barge in like this, can I use your phone?"

"Where's the Doctor?" Martha asked, glancing down the street behind her.

"Well…" Donna paused, looking uncertain for a moment. "I don't actually know. That's why I need to call. I haven't seen him since the night we saved the world. Or, the last time I saved the world anyway, I don't know if he's done it again by now."

"You sound just like him," Martha observed with a small smile. "Part of the DoctorDonna thing, yeah?"

"Right, exactly," Donna smiled at her again but it was strained. "So, mobile?"

"Of course, it's right through here," Martha led her to the kitchen and made a quick introduction to Tom before dialing the phone and handing it to Donna.

"Hello, Doctor!" Donna said cheerfully into the phone, wincing slightly as a shout came through it. "Oi! I need that ear, thanks. Yes, I'm fine! Memory's back, yeah, but I'm not burning or anything. He fixed it." She paused, listening to what the Doctor said with a frown. "It doesn't really matter who he is. Well, yeah it kind of does but- Listen, this is important! Pick me up at Martha's. Same place it was last time. Bit of an emergency, yeah. What?" Donna's eyes narrowed and she scowled. "Doctor, you are coming right now. No, that's not an issue anymore. I promise! Can't really go into that now…" she trailed off, glancing at Martha. Martha didn't like that look one bit. Donna was hiding something. "Look, I'm telling you the date and the time. You better be here before I've even hung up the phone!"

"Do I get to meet him?" Tom asked, leaning against the doorframe as Donna rattled off the essential information.

"Maybe, if there's not disaster looming," Martha replied, taking the phone back from Donna. "Is there disaster looming?"

"Not for you," Donna replied after a second's hesitation. "Well, a little?"

Martha raised an eyebrow. "You're not telling me something."

"And I am doing a great job of it, too," Donna said with a forced laugh as she stood up. "You really don't want to know, trust me."

"Donna, you show up on my doorstep at nine o'clock at night. You ring the Doctor and have to convince him to pick you up. I really do want to know."

"Not right now, you don't," Donna insisted before she sighed and looked away. "Sorry, I can't balance very well between the Doctor's mind an my own. I'm still not used to it. If I sound a little fuzzy, that's why."

"Donna," Martha began slowly, "What don't I want to know?"

Donna looked at her, her eyes suddenly very old and Martha realized why Donna needed the Doctor. "There's nothing you can do."

"You're scaring me," Martha said quietly, causing Tom to come to full attention.

"Everything okay?" he warily asked the two women.

Donna nodded at him before returning her attention to Martha. "The minute this is over I will find a way to tell you."

"What's so scary that I can't know about it?" Martha demanded, thinking back to what Donna said on the phone.

Doubt danced across Donna's face and she hesitantly opened her mouth, but the sound of a TARDIS materializing in Martha's front hall interrupted her. Donna quickly passed Martha and was at the TARDIS as the door swung open.

"Donna!" the Doctor exclaimed in surprise, staring at the woman like she was a ghost. "How did you get your memory back?"

"You lost your memory?" Martha repeated, shocked. "How did that happen?"

"Sorry, we don't have time," Donna replied, pushing the Doctor back into the TARDIS. "Emergency, we've got to run."

"You can't just go off like that!" Martha protested as Donna stepped into the TARDIS and quickly shut the door. "I can't believe after all that she's just running off!"

"They don't seem to be making the fastest getaway," Tom said, staring at the unmoving TARDIS. As if on cue, the door swung open again and Donna poked her head out, looking guilty.

"Right, sorry. We'll be back, soon as we're done. And Martha?"

"Yeah?" she replied, fighting down the panic as Donna's face became serious and grim.

"Call us at the first sign of trouble."

"What kind of trouble?" Martha asked slowly.

"You'll know," Donna said quietly before shutting the door. The TARDIS dematerialized, the sounding filling the apartment.

"He was easier to push around than I expected," Tom said, trying to make Martha laugh. When he failed he pulled her into his arms. "You going to be okay?"

"Yeah," Martha said with a shaky sigh. "Tea?"

"That'd be lovely," Tom murmured into her hair. They stepped into the kitchen as they heard the TARDIS materializing again, this time in the den.

"Solved it already?" Martha asked, shaking her head in relief, turning back towards the hallway as they heard the TARDIS door open. "Well, at least they didn't make us wait very long. I wonder what the problem was?"

"The problem, Miss Jones," the smooth voice that haunted Martha's dreams announced as it cut through the apartment, "Is that the Doctor and Donna Noble are far too predictable."

"It can't be," Martha gasped before she twisted in Tom's arms, scrambling for the phone. It exploded as she reached for it and she turned to see the Master lowering his laser screwdriver.

He smiled at her expectantly. "I love reunions, don't you?"
