The Doctor, Rose and Jack walked out of the resort and over to the beach where some other people were relaxing. They all lay on the beach for about an hour. The Doctor was worried about the vision he had but he never told Jack or Rose about it because he didn't want to scare them, especially Rose, but he needed to find out who the hooded figures were so he could stop them from.....killing Rose.

"this is nice" said Rose

       "yes it is" said Jack and The Doctor

    "hey Rose you want to go swimming.... as a mermaid?" asked the Doctor

" hell yeah... wait how?

      " I've got three biology changers in the TARDIS. It changes the biology of anyone who wears them. I'll be back in a bit"

Rose was ecstatic to swim like a mermaid, so was Jack. The Doctor ran into the TARDIS and ran through the hallway to the right, turned left, right and left again until he arrived at the storage room. He looked on shelves, through chests and boxes. He found them in one of the old boxes he took with him from his home when he left all those years ago.

The Doctor got back to the beach and found Rose and Jack. The Doctor put one changer on Rose's wrist, one on Jack's and one on himself. At this point Jack, Rose and The Doctor were all in their swimwear. The Doctor set all the Biology changers to mermaid, although on Populas they were called Cien's. All three of them walked into the water until they were fully underwater, and turned them on, within seconds their legs disappeared  and tails appeared on the three of them. The lights on the changers were blue, however the Doctors was green because he wasn't human the changer had to be put on a different setting than the other two. Jack's tail was blue, Rose's was purple and The Doctors was green.

 The three of them were swimming under the water for hours. (since they could breath under the water) They didn't even realise they had been swimming for about five hours, they got out the water and reset the changers back to human and Time Lord and decided to go for dinner since it was now about 5pm earth time. It happened again, when The Doctor walked into the resort he felt that weird feeling again, but this time Rose had noticed but didn't say anything.

Rose and Jack and gotten their food and sat at a table, The Doctor was still getting his food.

" It happened again Jack, I saw him stumble at the door, somethings wrong with him" said Rose

      "He would tell us if something's wrong wouldn't he?" asked Jack

"Have you met him? He never tells us if somethings not right"

      " Maybe he doesn't want to worry us"

    " What we talking about?" asked The Doctor as he sat at the table

" You, it happened again when you walked through the door and don't say it didn't I saw you stumble."

    "I'm fine Rose, stop worrying, its just a feeling like somethings not right but I cant place it"

" what do you mean a feeling?" asked Rose

     " Time Lords are telepathic remember I'm just picking something up and its doesn't feel right, that's all"

"Your mind was interfering with my medical scanner earlier when you collapsed, I scanned you and it wasn't even registering you as a person." said Jack

    " Okay, I'll admit that's weird"

"Exactly, so what going on with you, you wouldn't just collapse over a feeling?"

    " I don't know but I will figure it out okay.?"

"Okay" said Rose who still had a worried look on her face.

After dinner the three of them went to their room and Jack fell straight to sleep on his bed, Rose however was looking out the window at the ocean still worried about the Doctor. As the Doctor walked out of the bathroom after cleaning his teeth, he noticed that Rose looked scared and worried.

"you okay?" asked The Doctor

     " yeah just thinking" " you would tell me if something was wrong wouldn't you?"

" yeah of course I would. If I get the feeling again I'll tell you, promise, get some sleep"

      "okay"

She kissed him on the cheek and got into bed and went to sleep. The Doctor stared at her for about an hour before falling asleep in the chair in the corner of the room.
