A/N Caleb who is 14 and Sophia who is 12. Hope you enjoy this! :)

As Rose started to wake up she saw her daughter sitting next to her.

"Mom." Sophia said hugging her mother as Caleb came over also hugging Rose, who happily hugged back her children, who she loved dearly.

"What happened?" Rose asked not being able to remember when she became the bad wolf.

"Don't you remember." The Doctor said as he looked at the TARDIS console.

"It's like there was this singing" Rose said.

"That's right. I sang a song and the Daleks ran away" The Doctor said making Caleb and Sophia smile because they know that didn't happen and what did happen was so much worse.

"No it.." Sophia began saying but interrupted by The Doctor. "You two go to bed"

"Why?" Caleb asked as he started to walk.

"Because i said so" The Doctor.

"So moody." Sophia muttered under her breath as JJ nodded as to what his sister was saying.

"I was at home. no, I wasn't , I was in the TARDIS, and there was this light. I can't remember anything else" Rose said as she looked at the doctor, as he looked at his hand as it darkened.

"Rose Tyler. I was going to take you and the kids so many places. Barcelona. Not the city Barcelona, the planet Barcelona. You'd all love it. Fantastic place. They've got dogs with no noses" The Doctor said as he laughed as did Rose. Imagine how many times a day you end up telling that joke, and it's still funny"

"Then why can't we go"Rose said confused.

"Maybe you and the kids will. maybe I will just not like this" The Doctor said.

"Your not making sense" Rose said even more confused than before.

"I might never make sense again. I might have two heads or no head. Imagine me with no head" The doctor said as he laughed, as did Rose "And don't say that's an improvement. Rose, remember when I told you that I can regenerate where all my body changes. Well, it's happening." The Doctor doubles over in pain.

"Doctor!" Rose shouted as she went towards her husband.

"stay away!"the doctor shouted making Caleb and Sophia worried wanting to go back to the console room.

"What's going on" Caleb said a him and Sophia came walking into the room.

"I absorbed all the energy of the time vortex and no ones meant to do that. Every cell in my body's dying" The Doctor said.

"Can you do something? Sophia asked. The Doctor and Rose had never told Caleb and Sophia about regeneration. They always put it off.

"Yeah I'm doing it now. Time lords have this little trick. You two and the baby will have it to." The Doctor said pointing to his children. "It's sort of a way of cheating death. Except it means i'm going to change, and I'm not going to see any of you again, not like this not with this daft old face. And before i go" The doctor finished.

"Don't say that" Caleb said as he kids stood by her.

"It'll be ok, Caleb. I'm not leaving I just won't look the same. I'll see be your dad." The Doctor replied smiling to each of his children.

"Rose before I go,I want to tell you that you were an amazing wife to me and I love you so much. You, Caleb and Sophia. I just want to tell you all that you, were fantastic. Absolutely fantastic. And do you know what so was I" The Doctor said as he began his regeneration. Sophia burying her face into Rose's arm and Caleb just watching in shock as a new man appeared with his dad's clothes on.

"Hello. Okay. Ooo, new teeth. That's weird so where was I oh that's right Barcelona" The Tenth Doctor said as everyone just looked in shock at this new man.

A/N hope you enjoyed it if you do please review! :)
