The TARDIS shook and that was a surprise since River was the one driving. The Doctor couldn't see the coordinates, which was annoying him to no end.

"River, where are we?" he exclaimed angrily, clumsily walking towards her.

"I don't know, you tell me, it's your TARDIS!" She replied rolling her eyes.

"Well, maybe I would if you let me see the screen!"

"It was supposed to be a surprise!"

"That surprised you?"

River glared at him, "No, but that's not the point. Just open the door and see where we are because the TARDIS is refusing to take us anywhere else."

"Fine" pouted the Doctor, just like the child he is, and opened the door to see a familiar sight of Cardiff and Captain Jack Harkness running in his direction.

"Oh, hello Jack!" he waved happily to his long date friend, not noticing the terror on the other's face.

Jack practically jumped inside the TARDIS and closed the doors immediately, "Hello Doctor, nice seeing you here," then his gaze went to the woman inside the time machine "and who's that beautiful woman over there?" he asked with a charming smile and kissing her hand.

"My wife." The Doctor replied harshly and glared at his friend.

River just smiled to the now, shocked Time-Agent, "Don't worry he's always grumpy." Then turned to her husband, "Sweetie, he was just saying hello, there is no need to be so mad."

Jack grinned, "Oh, I like her. How did you even meet each other?"

"Oh you know," River started "Just your usual meeting like, I first saw him when I was born, then the second time my mother tried to kill me and the third time I tried to kill him, succeeded and finally saved him, you could say our love story started there." The Captain's eyes were bigger than tennis balls then he laughed.

"Oh Doctor, you just had to find someone as complicated as you are"

The Doctor smiled, at least the only friend that would be able to keep up with his immortality has accepted his wife, not that anyone wouldn't accept River, she just wormed her way to people's hearts. Then he remembered something, "What were you running from Jack?"

"You know, secret American organizations that have big guns and want me for something." He had just finished that sentence when they heard a big bump at the door.

"Jack Harkness and the Doctor, we know you're inside of the TARDIS, so either open up the door or we'll have to break in" They listened to a male voice speak from outside the TARDIS.

"Yep, they are the ones I was running from" Jack stated, smiling apologetically for not telling it before.

"No kidding! Would have never guessed that!" the Doctor exclaimed sarcastically as he walked to the door and opened it. "Oh, oh, ooooh" a big smile could be seen on his face.

"Captain Steve Rogers! Nice seeing you here! What can I do for you? Would you like some tea, cookies, maybe bananas?"

The super soldier blinked at the hyper man in front of him, after a couple of seconds he recollected his thoughts and replied, "Uhm, no thank you, Mr…?"

"Doctor, just the Doctor. My wife makes a mean tea, but that's not why you're here for, right?" The alien asked nicely, Captain America in his TARDIS, ha! Amy and Rory would love this.

"You're right. I'm here representing SHIELD, the director, he has requested your presence as well as Mr. Harkness'." Rogers said politely. Going to the diplomatic route, much better than whoever knocked on the TARDIS's door.

"And if I refuse?" the Doctor asked, curiosity burning in his eyes.

"Then I'm sorry to tell you, sir, but we'll have to enter your time machine and take you, Mr. Harkness and the woman with you to the headquarters of SHIELD with us" Steve said politely.

"SHIELD? What is SHIELD? I wanna know what SHIELD is. Take me to SHIELD! Take me to your leader! I 've always wanted to say that! Well, I did once, but I'll say it again anyways!"

River came over the door, "Sweetie, don't get over excited they have big guns and SHIELD stands for Supreme Headquarters, International Espionage, Law-Enforcement Division. Am I wrong Cap?"

"Nope" came the answer from inside the TARDIS.

The archeologist smiled, "Not you Captain! This handsome Captain here!"

"You're saying I'm not handsome, ma'am?"

"Not at all" she winked at him "But why don't you come out and check him yourself?" she smirked, which made Jack curious. When he approached the TARDIS' door he had a cheeky smile on and his so well known flirtatious look.

"Well, I couldn't agree more with you, ma'am. Maybe I wouldn't run away had I know such a breathtaking person was after me" with that, Captain Jack winked at Captain Rogers, which made the latter become as red as a tomato.

The Doctor rolled his eyes, "Jack…"

"Oh shush it sweetie! Leave him, he's a big boy."

"That's the problem."

After recollecting his thoughts once again (for a whole different reason now), Steve asked, "So you're coming?"

The Doctor and his wife replied with a simple "yes". While Jack replied, "With you for company? Wouldn't miss it for the world!"
