Family issues

The Console room was humming with the usual array of sounds as the Doctor leapt around the control panel making sure to land the TARDIS without the engines phasing and destroying Cardiff.
"Sweetie, we've landed. I'm just waiting on an old friend of mine to show up then we will be off again." The Doctor blared over the intercom.
"Okay I'll be up when the soufflés are ready." Clara replied cheerily.
The Doctor stood smiling to himself. Of all the companions he has had on the TARDIS she was the first to use the kitchen. Then again that wasn't the only thing she had done that other companions hadn't.
"Are you ever going to tell me who he is?"
"He prefers to introduce himself" he replied, then muttered "just before he hits on the nearest person with a pulse."
He had barely had time to straighten his bow-tie before there was a loud knocking on the doors. With a snap of his fingers the doors flew open to reveal Captain Jack Harkness.
"Doctor!" Jack exclaimed as he strode in and embraced him.
"Its good to see you Jack, its been too long." He said, obviously happy to see his friend again.
"Damn right it has been, you've regenerated since last time I see." Jack said as he looked over the time lord's new body. "Bit scrawny don't you think?" Jack teased.
"hey, I like this body, this body is cool." said the obviously offended Doctor.

" I hope you both like.." Clara stopped dead as she appeared from the kitchen. "Dad? What are you doing here?" exclaimed Clara with an expression of shock and joy across her face.

"Dad? He's your dad!?" The Doctor spluttered turning several shades paler.

"Clara, It's good to see you! What are you doing here? Jack joyfully hugged his daughter.

"Sorry, Jack is your Dad?"

"Didn't see that coming did you chin boy" smirked Clara cheekily.
