"I still can't believe it! Dogs with two noses!" Amy and Rory laughed and discussed the latest planet the doctor had taken them to.
Trying to concentrate on re-calibrating the TARDIS he set his mind on the discombobulator and soniced it, standing up the Doctor prepared a cheeky grin but before he could turn to his giggling companions a feeling of nausea and pain swept over him. Doubling over, he prepared to steady himself when someone came behind him and did it for him.
"Doctor are you okay?" Amy's concern filled his head and he took a moment to regain his composure.
"I'm fine." He expressed looking in Amy's eyes, "You look like someone's just killed those dogs with two noses!" laughing the Doctor tried to shy some of the worry away but the questions just kept coming.
"You're lying, I can tell! You're a terrible liar!" Amy folded her arms like a stubborn child and refused to give up until she had got something from the Doctor.
"It was just head rush!" even though he knew he didn't get head rush, it was the simplest explanation for what had happened and it seemed to work for him.
"Doctor, I'm pretty sure head rush doesn't have you doubling over in extreme pain." Rory said a little cockily.
"Err, It was a special…Type of head rush?" The Doctor said feeling a grin spread across his face.
"Uh huh." Amy said raising one eyebrow.
"Uh huuuuh!" The Doctor laughed and returned his attention to the TARDIS console hoping that his nosey, stubborn companion didn't carry things on.
"Rory?"
"NO! I'm not doing it!"
"What? You're not doing what?" The Doctor questioned.
"Please Rory I just want to make sure he is okay." Amy pleaded until Rory gave in.
"Okay Doctor, stay still for one second." With Rory advancing towards him the Doctor could do only one thing but… "THERE'S A GIANT LIZZARD BEHIND YOU!"
" WHAT! WHERE!" both of his gullible companions turned to face the door when it dawned on them…
"YOU TRICKED US!" they both said in unison, suddenly, the doctor grabbed a small object and pressed it and then he disappeared, into thin air.
"Doctor? Doctor where are you?" Amy asked puzzled, she was about to scream at him to stop being stupid, when he appeared on the other side of the TARDIS.
"Invisibility cloak! I didn't think…" They turned around just in time to see him tumble to the bottom of the stairs.
"DOCTOR!" The loyal companions ran over to the lifeless body, pressing his ear to the Doctors chest Rory a relieved Rory looked up at Amy.
"He's breathing, but his pulse is very weak."
"What's wrong with him?" Amy questioned.
"I don't know…"
