The Tenth Doctor's POV – The TARDIS

I landed the TARDIS about a mile away from Tony Stark's house. I was panicking. If he didn't tell the boy he wasn't his real father all of time and space could collapse. I saw that is was morning when I ran out of the TARDIS. It was probably already too late. I ran to Tony's house and rang the doorbell several times before getting an answer.

"Did you tell him you weren't his father?" I asked in a panic.

He stared at me for a second confused as Martha caught up with me. It had been almost a month since I last saw Mr. Stark, but for him it's only been a few hours. He looked at Martha slightly confused, and then I saw the boy come down. I hadn't seen him since he was a baby, so I wasn't shocked to see how much he'd grown. He had bright green eyes and messy black hair that barely covered a scar on his forehead. I knew this scar was a curse, but I didn't know how much he knew. I smiled at him.

"Yes, Doctor?" Mr. Stark asked, snapping my attention back.

"Did you tell him? Because it is crucial that you tell him. If not last night then now," I said hurriedly.

The boy looked at me completely confused along with Mr. Stark. They looked between each other and me before Mr. Stark finally realized what I meant. Humans can be so slow sometimes!

"Oh, I told him last night. I let him read the letter that you left. He hasn't read the one from you know who yet. I'll let him read it after he gets his other letter," Mr. Stark replied.

I nodded, relieved. Martha stared at me as if I was crazy. I hadn't explained any of this to her, but I didn't know how much I should tell her.

"Oh, Martha, this is Mr. Tony Stark and his son…"

"Harry. His name is Harry," Mr. Stark informed me. "Nice to meet you Martha."

"Yep, good old Martha Jones. I met her about two weeks ago," I replied.

Harry spoke up for the first time that I heard. His voice was confident and full of excitement. He seemed just happy to be there.

"Hello! Nice to meet you Ms. Jones," Harry greeted her with a big grin.

"Oh, and Harry, this is the Doctor. He's the one that brought you to me when you were a baby," Tony explained to him.

"Doctor who?" Harry asked.

I grinned, expecting that response. I had heard that one everywhere I went and it was asked by everyone I met. I loved the question almost as much as I loved hearing "It's bigger on the inside!", which was a lot.

"Just the Doctor," I replied with a chuckle.

"Your voice sounds different," Harry stated.

Tony looked down at Harry surprised while Martha and I laughed. Harry grinned at us and I put my hand on his shoulder with a grin.

"We aren't from America. We're just visiting. Where we come from makes our voice sound different. To me your voice sounds different," I explained to him with a smile.

"Well, Doctor, I think it's time we're off," Martha mentioned.

I checked my watch and almost kicked myself. I was going to be late if I wanted to show Martha the first solar eclipse in the universe, which we would miss if we didn't go now.

"Oh, yeah. It was nice meeting you, goodbye!" I exclaimed quickly, running off with Martha.

Harry was a sweet kid, and I really liked him. It's a good thing, too, because I'd be spending a lot of time with him.
