Rory and Amy were woken up by a crash in the main room. Amy picked up her trusty baseball bat. They snuck downstairs carefully. Amy sighed as she saw the creamy-brown trench coat swish by the door.
"It's Cas!" Amy said.
Jack's messy brown hair and flirtatious grin popped around the door. "Morning!" he said in his American accent.
"Him I don't know!" Amy added, "Who are you?"
"Captain Jack Harkness!"
"Who?" Rory asked.
"The leader of torchwood. A friend of the doctors." Cas introduced.
"Right well, I'm just going to go and put some trousers on-" Rory began.
"Oh don't bother! I wouldn't want to make you do anything you don't want to!" Jack said. He didn't try and make it subtle as he glanced Rory up and down. Rory ran back upstairs to put some clothes on. Jack glanced at Amy the same way.
"Oi!" Amy said. She hit his arm.
"Ow!" Jack mocked laughing.
Rory made tea for everyone. He didn't have anything else to do. As he did, Jack and Amy were flirting. Jack kept flirting with Cas but it was lost on him. Cas was trying to keep them on topic.
"Why is it so important to find the doctor anyway?" jack asked.
"To make sure he's safe! He never answers his phone and we need to talk to him!" Amy said.
"And why does angel face over here need it?" jack asked.
"I am an angel. I do not just have an angel face!" Cas correct.
"If there's anything else angelic I'd like to see!" jack said.
"My true form would blind you." Cas said.
"Well what a last sight it would be!" jack clicked his tongue.
"Jack leave the poor guy alone! He obviously doesn't get it!" Rory said.
"Spoilsport!" jack grinned.
"So why do you need to find the doctor Cas?" Rory asked as he poured tea into Cas's teacup.
"What is this?" Cas asked.
"Tea? "Amy said uncertainly.
"Oh. I pictured it… different!" Cas said. He took a sip anyway. "Sam and dean wish to find this doctor. I will help them any way I can but I can't get to close to them!"
"Why do they want to find the doctor?" Amy asked.
"I don't know. I didn't question them!" Cas said.
"To find the doctor you have to find Martha Jones. She's got his number!" jack said.
"Who's she?" Amy asked.
"One of his former companions. A good friend of mine. She's the doctor at the government base of UNIT!" jack said.
"And she'll help us find the doctor?" Rory asked.
"Maybe. If he still has her phone!" jack shrugged.
"Where do we find her?" Amy asked.
"First you hack into UNIT's systems. I'll call Gwen and get her to get the exact instructions from Tosh's compute drive!" jack instructed as he left the room to enter the hall.
"I'll call Sam!" Rory said leaving to get his mobile from their room.
"I'll call Dean!" Amy said going to the landline in the hall.
"I'll… sit here quietly," Cas said. He didn't move.
