The Doctor smiled – taken by his new companion. Martha, Martha Jones. A good strong name that! His happy expression faltered. She had yet to face the hardest test that came with being a companion of The Oncoming Storm. Sure, there was the monsters, the facing the endless dark sides of a million races (including humans), the weapons, the death, the threat of accidentally being stranded in a different time zone or on a different planet, the endless, exhausting running. But then, on a whole other level, there was Harry.

Harry. His son, his pride and joy, his bloody nightmare! Since his tenth birthday the boy had become a little green eyed monster, glaring at anyone with the potential to be a companion. Sure, he was less thrilled to be entertaining another companion, but that was because of Rose – someone Harry had never known. He had travelled for three years alone before finding the miracle baby that was Harry. It had been lonely, the Doctor had hated almost every minute of it, mourning the lack of his Rose and the half cut of message. The fact he never got to say I love you.

But he had moved on, he understood that a new female human companion would dredge up the loss of the one companion he would never forget and always miss, however, it would open up new doors, new adventures, new opinions, a new chance to see the glory of the humans, those hairless apes and, of course, lots more running holding a hand (Harry refused to after his ninth birthday with the claim that he was a big boy now!).

Oh, who was he kidding, it was gunna be a disaster!

The Doctor twisted his head around the corner, craning his long, lanky body as to see around the corner seconds before his new darker doctor in training companion. For the first time, he winced at the sight of his T.A.R.D.I.S. Its blue panels were as welcoming as normal, but the ominous sight of two large but narrowed green eyes staring out the gap in the door.

They were glowing slightly as if the mischief in them had lit a torch inside of Harry that was escaping only through his eyes.

He couldn't help but guess at some of the attacks whirring in those glowing green orbs and the brain behind them and tried to squash the growing grin that was quickly spreading across his narrow face. He turned to Martha, still seeing the glint of bared teeth in the dark slot between the two T.A.R.D.I.S. doors (although he wasn't sure if it was in grin or growl they were bared), who looked apprehensive of the smile plastered unwillingly across he knew travelling companions face.

"Doctor? Why are you smiling like that?" her voice was even more apprehensive than her face, each word hesitant to leave her lips. The Doctor's grin faded, and was easily replaced by a frown. Had he told her about Harry...?

Oh. His mouth formed a little oh shape as he frowned in that was Harry knew meant he had forgotten something important and was now trying to figure out what to say to make it sound like forgetting the major object, incident or in this case person he had forgotten was ordinary, everyday or completely unimportant. (which, of course, it wasn't as Martha was looking for some alone time with the Doctor and making the mistake of assuming that Harry was Rose's and the Doctor's son would do nothing but get her alone time alone).

"Erm, well, Martha, I think there's something I should tell you..."

To all those not too busy covering their own arses to listen, a giggle, slightly reminiscent of a cackle from a witch or the laugh of an evil genius just creating life, echoed from the peculiar blue box in the corner of the street. Though what that foretold nobody but the green eyed second generation Marauder knew.
