The rest of the team was staring at the CCTV screen. Laying on Jack's old camp bed, Miranda was curled on her side, shut away in the isolation cell. Ianto had brought some blankets and clothes from her rooms to keep her comfortable.

"Evie can't get sick…" Fish gasped, watching Miranda cough into a handkerchief.

"She's running a fever. She's congested. She's coughing. She said her throat hurt," Ianto said, in pure disbelief. "She's sick. It must have been when she cut her finger on that glass slide."

"Is it all right to leave her in there by herself?" Gwen asked.

"Mandy insisted," Ianto said, shaking his head. "She didn't even realise she was sick. She thought she was just overworked and tired. She came up with a reasonable explanation for all of her symptoms."

"How long was it before the coma started in the others, Martha?" Jack asked.

"Four days after the symptoms started. The staff infected with Brian Wilson's blood fell into comas within hours of each other," Martha said, shaking her head.

Ianto shook his head too, "Mandy's immortal. Who knows how this will effect her? She might not fall into a coma at all. How are you feeling, Ethan?"

"Fine," Donovan said. Everyone was staring at him. "No seriously, I really do feel fine. When'd she cut herself on that slide?"

"Night before Cameron MacDonald showed up on the Plass," Ianto said.

"Oh," Donovan said, absently.

"What?" Jack asked.

"Uhhh," Donovan said and then gave a nervous cough. "We've been working a lot of late nights…"

"And you two haven't been shagging," Gwen supplied.

Donovan didn't say anything, just shifted nervously.

"What if we reset her?" Fish asked, eagerly changing the subject.

"Reset?" Donovan asked, confused. "She's not a fucking computer, Joe."

"No, but she's immortal," Fish said, rolling his eyes a bit. He mimed a gun with his finger, pointing it at his temple.

"We could give it a try," Jack said. He turned to leave so he could get his Webley but Ianto grabbed his arm.

"Jack, I don't think it's a good idea. She's sick. This is a completely unknown set of circumstances. We have no idea if she'll revive. What if, after she's dead, her body liquifies like the others," Ianto protested. "I don't think it's worth the risk."

"I think we're all missing the point here," Gwen said.

"What do you mean, Gwen?" Ianto asked.

"I mean, what would make Miranda sick?" Gwen asked. She pointed her hand at the screen, feeling as if she was stating the obvious.

"I see where Gwen's going with this," Donovan said. "She said she's seen hundreds, probably thousands of plagues and nothing's ever infected her before. She gets sick now?"

"The illness could just be alien," Jack pointed out.

"I don't think so," Donovan said, shaking his head. "I mean, think about it for a sec. What is it that keeps Miranda from getting sick? Have you guys ever studied what happens to her when she gets exposed to disease?"

Angry, Ianto snapped, "We don't experiment on Miranda and Jack."

"Take it easy, Ianto. I'm not talking about using them as fucking guinea pigs, I'm talking about what you guys see day in and day out. They get injured and you watch them heal, right? What? Two? Three days after I got here, a Weevil scratched her up pretty good. I watched those wounds heal. It was some sort of accelerated metabolism," Donovan pointed out. "What if the reason she doesn't get sick is the same? Some sort of advanced immunity? An alien disease wouldn't get at her any more than an old fashioned earth one."

"We're just guessing," Jack said, shaking his head. "We keep working this. Will and I have reacted strangely to alien artefacts before. Remember those Nepanthian energy weapons? Who's to say there isn't an illness out there that can make us sick? Fish? Go home and get Henry. Bring him here. I want to talk to him. Martha? I know it seems like we've got the perfect source of samples now but I don't want to use Will. We don't know what effect her immortality will have on things. Keep processing everything from the patients at the hospital. Gwen, keep working on the CCTV with Ianto. Ethan? I've got some things I need you to read about her."

Fish grabbed Jack's arm. He lowered his voice. "You're going to tell him about the Game? Evie didn't want that."

"I know but he needs to be in possession of all the facts. We need everyone on the same page now, Fish. The point here is to teach him and he isn't going to learn anything if we keep him in the dark," Jack said. He pointed at the hallway that led to the garage. "Go get Henry."

"I don't want him anywhere near this," Fish nearly snarled.

"I need answers only an immortal of the Game can give me and I need someone I know Will can trust." He ordered, "Go. Get. Henry."

Fish sighed and started towards the Hub garage. He sent a quick text to Henry, telling him to expect him home soon. He couldn't believe that Miranda was even sick but he couldn't deny what he'd seen with his own eyes. Fish didn't want Henry anywhere near the Hub and was a bit angry with Jack for asking him to bring Henry down rather than speaking with him on the phone.

With a sigh, he parked his car and got out. He climbed the stairs and unlocked the door, thankfully avoiding Mrs. Foster, his nosy neighbor. The sooner he and Henry moved away from her the better. The idea of have a gay couple living across the hall was quite novel to her. She was more nosy than ever, constantly popping round with baked goods so she could snoop and asking intrusive and inappropriate questions.

When Fish opened the door, he gasped. The flat was a completely disaster. Henry had emptied every one of the kitchen cupboards. Their contents were spread out all over the flat, covering every available surface. Fish's mismatched plates and glasses were everywhere. Every pot, every pan, and utensil was out on the counter, his coffee table and sofa. There were several bin liners open on the floor filled with all manner of things - chipped crockery and boxes of dry goods. Henry was on a step stool. He had on a pair of rubber gloves and was scouring the cupboard shelves. The smell of cleaning fluid was in the air.

"Bugger all, Henry! What the bloody hell are you doing?" he cried. "Look at my flat!"

Henry leaned out of the cupboard, quirking an annoyed eyebrow at his lover. For some reason, Fish still referred to the flat as 'his' instead of 'theirs'. Something which irritated Henry to no end. "I believe I live here too, Joe."

"I didn't expect you to move in and wreck the place!" Fish said, waving his hand around.

"I am planning on putting everything back. The cupboards are quite dusty, Joe, and most of your dry goods have expired and some have bugs in them," Henry said, patiently. He waved at the bin liners. "Much of your crockery is badly chipped and there is enough that you needn't hang on to the damaged items. It is only the two of us."

Henry stepped down off of the step stool and waved at the hall cupboard. He removed his rubber gloves and dropped them on the counter. "I'm afraid I've also broken your hoover."

"What?" Fish asked. "How?"

"The bag was overly full and I neglected to check before I used it," Henry said, sheepishly. "I'm afraid I've burned out the motor. I was going to head down to the storage unit for mine."

As Henry spoke, Fish winced. He actually couldn't remember the last time he'd changed the bag inside. He was always forgetting.

"The hoover's not your fault, Henry, it's mine. I've burned out two like that." He stood in place, turning, surveying the chaos. "We don't have time to put all this back…"

"Is something the matter, Joe?" Henry asked, wiping his hands. "Are you expecting a guest of whom I was not aware?"

"We need to get to the Hub. Jack wants to talk to you," Fish said. He leaned over and tied up one of the bin liners.

"To me? Whatever for?" Henry asked, surprised.

"Evie's sick," Fish said, flatly.

"Preposterous," Henry said with a laugh but it trailed off as he saw his lover's face. He shook his head. "Your Captain Harkness should find a better way of playing a practical joke."

"I'm serious, Henry. She's running a fever. She's coughing and… well, she's sick!" Fish insisted.

"Utter nonsense!" Henry cried. He moved some pans aside and sat down on the sofa so he could put on his shoes. "Fine, if you wish me to play along with this joke than I will do so…"

Now Fish could see why Jack had wanted him to fetch Henry rather than talking with him. Henry didn't believe him! Fish spent the first few minutes of the drive to the Hub trying to convince Henry that his teacher was actually sick but eventually gave up. Henry was becoming quite cross with him and it wasn't worth starting a row. He'd see the proof with his own eyes soon enough. He pulled into the Hub's garage and parked. Before Henry could get out of the car, Fish put his hand on his arm to stop him.

"Henry, promise me you'll be careful. If this thing got Evie, it could get you too," Fish said, afraid.

"I'm certain I will be fine, Joe," Henry said with impatience. He was rolling his eyes and shaking his head.

Henry followed Fish into Hub, down the long hallway from the garage. The moment the two men emerged, Jack strode across and held out his hand.

"Henry, good to see you again," Jack said as Henry shook his hand.

"Captain," Henry said.

"He doesn't believe me, Jack," Fish said.

"I figured. It's fine, Fish. Follow me, Henry," Jack said.

Henry followed Jack down the east stairs towards the isolation cell. "Captain-"

"Jack."

"Jack, I do not understand what joke this is that you and Joe…" Henry trailed off as he caught sight of Miranda. She was laying in the cell, covered in a blanket, asleep. Henry's eyes flicked to the monitors but the most startling information wasn't what was displayed on the screens. It was in Miranda's own face. Having lived in an age before modern medicine, Henry knew sickness when he saw it. She was sweating. Her pale complexion was waxy but her cheeks were flushed with fever. This was no joke at all! Fish had been telling him the truth! Impossible! Henry felt the colour fading from his own cheeks.

"God in Heaven!" he cried.

"Shhh, she's asleep," Jack said, waving his hand at him. "She's sick, Henry, and we don't know why. There are some trust issues between Will and I when it comes to this Game of yours. I need you to be straight with me here. Will says you people can't get sick but I need to know the truth. Is there anything that can infect your kind? Anything at all?"

In an emphatic whisper, Henry said, fearfully backing away from the glass, "NO! Our kind are immune to every illness! I have lived through the Black Death! The Sweating Sickness! Epidemics of small pox and measles! Spanish influenza! Malaria, cholera and typhus! HIV! This is NOT possible!"

"It's safe, Henry," Jack said, raising a calming hand. "The cell is sealed and on its own ventilation. The illness isn't airborne. It's blood borne."

"How was she infected?" Henry asked, not believing he was asking such a question.

"A slide broke. She cut her finger on the glass," Jack said, softly.

"You must keep her condition secret. None of our kind can know she is incapacitated. The others… the Watchers… no one can know that there is an illness to which we are vulnerable." Henry tilted his head. "Have you tried killing her?"

"Not yet," Jack said. "We've no idea what is going on here. We're afraid-"

"That if you kill her, she may not revive," Henry finished. "If the disease kills her, she may not revive either. How high is her fever?"

"Thirty nine point five."

Henry furrowed his brow.

"One hundred and three point one," Jack supplied.

Henry's eyes went wide. "Is she lucid?"

"She's sleeping a lot but when she's awake, she is," Jack said, leading Henry back into the main Hub. "C'mon, I don't want to wake her up."

"I'm sorry I cannot help you," Henry said, sadly. "Are you safe? Mao-Lin informed me that your immortality is different than ours."

"We don't know," Jack said, shaking his head.

"Who is taking care of her?" Henry asked.

"I am," Jack said. "Even though we don't know if I can get sick or not. It's the least risky."

"I shall take over her care," Henry said, immediately.

"I can't ask you to do that, Henry-"

Henry interrupted, "I am not asking, Jack-"

"-because Fish would kill me," Jack said, talking over him.

Henry drew himself up. "I believe Torchwood was formed by the Crown, Captain Harkness. As the acknowledged son of King Henry VIII-"

"Don't play that card with me, Henry," Jack said, pointing his finger in Henry's face. "You want to take care of her? You clear it with Fish and I'll let you."

Henry's face fell and took on a nervous sort of panicked look.

"Yeah, I thought so," Jack said. He pressed his lips together into a thin line. "Look, I really don't have a problem with you chipping in. I'm down an immortal team member and you did good last time. But I don't want to hear it from your boyfriend."
