Tony Stark walked into the room, head high and smirking.

"My turn yet?"

Martha froze. "Well, yes, but we didn't call you yet…"

"Oh, well. I guess you can start now. No need to call me when I'm already here."

Martha looked at Jack, and Jack shrugged. "Okay, Mister Stark, over here, please, for your weight."

"Wait!" Tony said. "You didn't introduce me to your friend, doctor…"

"Doctor Martha."

"Ah! Doctor Martha. So tell me Doc, who's this friend of yours?"

"Yes. Mister Stark, Nurse Jack."

They shook hands. "Nice to meet you, Mister Stark. I am very fond of your work."

"Thank you, Jack. Nice coat. Do you think you should be wearing that over scrubs?"

The nurse shrugged. "No health violation. It's clean."

Tony made a face and stepped on the scale.

"And how are you, Mister Stark?"

Tony smirked. "Oh, I'm fine. You know, battling criminals, caging psychotic gods who are trying to take over the world, making people kneel at his feet, that sort of thing."

"Yeah, we've done that before…" the doctor mumbled.

"Excuse me?"

"Huh? Oh, nothing, just thinking. This way for your height."

"You know, I have technology that can scan the body and get this information within seconds."

"Yes, well, we like the old fashioned way. Isn't that right Jack?"

Jack didn't reply. He wasn't sure if she was making a reference to what time he was from or just making small talk. Speaking of time…

"What's wrong with your buddy there?" Tony asked. "Sulking over something?"

"Oh, uh…sort of." Martha wrote down his height. "And how is your arc reactor?"

"Oh, the pacemaker?" He beat at his chest. "It's doing fine. Although, you really shouldn't be worrying about that."

"Well, sir, I'm a doctor. I'm supposed to worry."

"Yes, a doctor. Tell me, how did you get aboard the heli-carrier?"

Martha hesitated, and Jack stood up.

"Oh, come on, you can tell me," Tony said.

"We, uh, came aboard a transit plane, when it arrived yesterday."

"Ah, but there was no transit plane. I checked the security and look what I found."

Tony pulled a remote out of his pocket and pointed it at one of the monitors. The monitor sprung into life, and showed a recording of Martha and Jack coming out of the bathroom. The same bathroom. The recording showed them looking around for a moment, then turning around as someone inside the bathroom was giving the instructions. The recorded Martha and Jack nodded, and the bathroom door closed. The recorded Martha and jack looked at each other, squealed and jumped in excitement, then ran down the hallway, out of the sight of the camera.

The monitor turned off, and Tony turned toward the 'doctor' and the 'nurse'.

"So, I think we can all guess that you two didn't come from any plane, but from a restroom! Now, I didn't tell anyone, but from the looks of the cameras, you don't seem to be any threat. If anything, I would say maybe tourists. But one thing still isn't clear." Tony's face turned dark. "How a heavily guarded plane suspended multiple miles off the ground can overlook two passengers that have no clearance or ID's. Now I'm going to ask again: How did you get on the carrier?"

Martha looked at Jack, and Jack shrugged. "You think he'll believe us?"

Martha shook her head.

"Alright. Here's what happened. We've been traveling with this guy who can go anywhere in time and space. He travels in this blue police box that's bigger on the inside. A few days ago, he dropped us off here and told us to 'lie low' while he talks to this Fury guy about a future threat. So we've been posing as a doctor and a nurse until he comes back."

The bay was silent for a moment. Then, Tony spoke.

"Oh, is that it? I was wondering when the unicorns and magic glitter would show up."

"Well, actually-." Jack started.

Martha looked at him as if to say, "Don't even mention it." Jack closed his mouth.

Tony looked from the doctor to the nurse. "And…this is the story you're going on?"

They both nodded. "It's the truth."

Tony slowly nodded. "Huh. Okay…well, since you guys aren't really, well, sane, I'm going to talk with Fury. Until then, keep playing 'Doctor'. Just don't, uh, kill anyone." And with that, Tony backed out of the room and shut the door behind him.

Martha crossed her arms. "Well, that went just great."

"Well, it could have been worse," Jack countered.

"Oh yeah? How?"

"He could have laughed and then called security to arrest us."

"…True. Very true.
