Chapter 2

River smiled as she watched the Doctor lean over and brush a piece of hair away from Trevor's face. Carefully standing up, he crept out of the room, quietly closing the door behind him.

The two parents walking down the hall hand in hand; "So Professor Song, what do you suggest we do tonight?" He smiled, kissing the back of her hand as they entered the console room.

"Oh, sweetie " she responded with a smirk. "Don't you know how to spoil a girl." She released her hand from his grip and kept walking, circling her way around the Tardis.

"You know...It never ceases to amaze me, just how beautiful she is" She stopped, waiting to hear a response, furrowing her eyebrows as she frowned " Doctor...?" There was no response. "DOCTOR?!"

He looked up "Hmm?"

"Doctor what's wrong?"

"Nothing is wrong River"

"Don't you tell me nothing is wrong, I know that face,"

"What face?"

"There! Your doing it now! Its your thinking face!"

"Oh is that what you call it now?"

"Doctor..."she dangerously warned.

"Its nothing, really. It's just Trevor.."

"TREVOR?!"

"Yes, Trevor, now please stop shouting, I'm trying to think."

River crossed her arms across her chest, "And what might that be?"

The Doctor stared at her, knowing that she wasn't going to let the subject pass without a fight..."Chase."

River moved her hands to her hips "Chase? Who is Chase?"

He walked around the console and stood in front of his wife. "Chase is not a who, but a what, and that what being a game."

River raised an eyebrow "Sweetie, I'm not quite following you."

The Doctor turned to the console and began pressing buttons, "Like I said its nothing...NOW! Where do you suggest we go? How about somewhere beachy? I like a good beach!"

River ran around the console to face her husband," You can't go changing the subject like that! What about Trevor!?"

The Doctor smiled "Well I suppose he can come along to."

"Doctor, you know that is not what I meant!"

He looked up from the console to find his wife looking terribly nervous, pulling down a lever, he walked over speaking softly "River... the last time I've seen you this nervous was four years ago ."

River laid her head under his chin as he pulled her into a hug. He spoke up as he wrapped his arms around her, "I promise you, there is nothing to worry about." He placed a kiss on her forehead and held her in a hug. He knew River was never this emotional, but Trevor was a special case, bringing out the strongest of emotions in the both of them.

River lifted her head from his chest and gave him a sweet peck on the lips," I'm going check on Trevor." He released her from his embrace and watched as she walked through the arch and down the hall.

Once she was out of eyesight he dashed to the computer monitor to pull up hallway footage. Combing his hands through his hair, he watched as his son was revealed on the screen running through the halls shouting "You can't catch me! Try and catch me!". He watched the segment over and over, until finally turning his back to the evidence, rubbing his face he whispered in dismay "I was right." He turned back to the monitor watching the screen one last time, praying that the clip had changed, but it only revealed the same thing, Trevor running throughout the halls playing chase and calling to someone who wasn't there...

River sat in the doorway with her head against the frame, watching her little boys quite figure peacefully sleep. Taking a deep breath, she closed her eyes and began thinking about one of her most cherished memories, the day Trevor was born.

"River, he is so tiny."

"Well what do you expect sweetie, he is a newborn." River smiled, he had been so nervous while holding Trevor for the first time.

"He has your eyes River, he has those sexy blue eyes that I thought where impossible to replicate."

"Sweetie, you just called our son sexy." "Sorry kiddo, but your mums eyes really are breath taking...yes yours are too...you want me to prove it?"

"Who are you talking to?"

"Trevor."

"Your lying."

"No really, I speak baby, and he wants to see your eyes." The Doctor sat next to River, allowing her to adjust herself before easing the little time lord into her arms. He rapped an arm around River and placed a kiss on her forehead, the two parents gazing at the little life.

"Yea buddy, I know. Bow ties are cool."

River smiled at the memory, touching her forehead where she swore she could still feel his kiss. She slowly opened her eyes grinning at the sight of her husband crouching next to her, realizing that he had kissed her as a ploy to try to wake her up. The Doctor stood up and offered her his hand, gratefully taking it , River didn't let go once she was standing and quietly closed the door before walking away.

"Someone looks happy."

"I was thinking about when Trevor was born."

"Really?"

"Yes really! Why do you sound so surprised, it was a life changing moment for us."

The Doctor sighed, "That it was... Remember how we were talking about Trevor earlier?"

Rivers face hardened "Yes."

"Well what if I told you that Trevor has played with something we can't see?"

River couldn't help but smirk "What?"

The Doctor began to grow impatient "I watched the hallway footage from earlier and Trevor was playing chase and calling to something that wasn't there...why are you smirking?"

"Oh sweetie, only if mum and dad were here to explain this one to you."

The thought of Amy and Rory brought pain to his heart, "How is this funny? Shouldn't we find somewhere safe for him to go until we figure out what made its way onto the Tardis?"

This comment only made River's smile bigger. "Doctor! Trevor is only four years old, having an imaginary friend is completely normal for a child his age, even if he is only a quarter human!"

"But River he is our child, and I can speak for ourselves when saying our lives aren't what one would call normal."

Hearing that concerned River, trouble seemed to follow them where ever they went, and it was difficult enough childproofing the Tardis let alone protecting a curious four-year old who was just like his father. "Maybe its time we pay a visit with Brian?"

"Right, perfect, that's a great idea. When do you suggest we go? How about now?"

"How about tomorrow sweetie?"

"Right, that works to."
