Elizabeth wandered into Amy's room. The lights were low and the only sound was of the gentle beeping of the machines that were keeping her internal organs alive. She stepped softly, trying not to disturb her. Amy opened her eyes. "Hey." she said with a weak smile. Her lips were even pale. Liz tried her best to smile back. The grief in her welled up and she fought to keep from crying.

"Hey back." she said quietly. "You feelin' better any?"

Amy shrugged. "Feel like I've been hit by a truck." She smiled again. "I need a drink."

Liz laughed. "Yeah, me too." she said as she sat down. "I have some interesting things to tell you though."

"OK, shoot." Amy said.

"Well....." Liz started. She told her all about the two of them being sisters and how they both carried the same gene for this disease but somehow Amy's had been activated. Now they were all trying to figure out what was making her body kill itself. "Any ideas?" she asked.

Amy chewed her lower lip. "Sisters, huh? Like real sisters?" Liz nodded. "Teach is gonna flip." she said thoughtfully. After a few more minutes she added. "I got nothing. I haven't been sick since the whole thing with Joaquin went down, you know that."

Liz's face went pale. "I'd forgotten about that." she said. Her voice was distant. "I'll have to tell House, you know that, right. He's your doctor."

"He is?" Amy asked. She seemed pleased. "Good. Things are going to be alright then."

"If he doesn't kill you or both of us in the process." Liz mused.

Amy waved her free hand in the air dismissively. "Just tell him that Teach will be pissed if we die. And he'll never get laid ever again."

Liz laughed. "That might actually work. From what I've heard. Typical middle-aged male."

"Who, me?" asked House as he stepped into the room.

"Yes, you. You old fogey." Liz said. House stuck out his tongue at her. "You better stop, or I'll tell Momma."

House's eyes went narrow. "You wouldn't?" he asked suspiciously.

"Wouldn't I?" Liz asked in return.

"What'd she say on the phone?" he asked.

"What are you in here for?"

"I asked first."

"My question is decidedly more important."

"Good point. What'd she say?"

"House!" Liz crossed her arms on her chest and gave him that 'answer me, right now' look that he would know she'd learned from Jesse.

He shifted uneasily under her glare. "I still have nothing."

"What about the flu?" Amy asked from her bed. "I caught Joaquin's bird flu. He cured me with his little vaccine, but It messed me up pretty bad."

House's jaw went slack. "Joaquin used you as one of his guinea pigs?! That... I'll....He'd better never...." House stammered and started to pace the tiny room. "This makes a lot of difference. I have to run all the test over again."

He turned on his heel and swept out other room. "Just then, he kinda reminded me of Dr Frankenstein on his way to the rooftop lab." Liz remarked. Amy could only groan.

On his way down the hall he passed Wilson. "She's with Amy." he said without stopping.

James stopped still in his tracks. He hadn't planned on asking where Liz was, but now that he new... he might as well stop in and say hello.

The closer he came to the room the clearer the sounds of feminine laughter became. At least Liz was keeping Amy in good spirits. He edged closer to the door. Suddenly the room went silent. Wilson frowned, immediately thinking the worst. Just then the form of his beloved girlfriend appeared in the doorway and shouted "Gotcha!"

James Wilson nearly jumped three feet into the air. He yelped and grabbed his chest in reaction. "Jee-zus you could have given me a heart attack." He said though gasps.

Liz touched his face, felt his chest and suck out her lower lip. "You're fine, you big baby." She turned around. "Besides, it was Amy's idea. Gotta humor the sickie."

"Shut up, skank." came Amy's voice. "Don't call me sickie.. sick-o."

"Bite me." Liz retorted. "Sickie."

"Whore!" Amy snapped.

"Bitch!" Liz replied.

"Yeah, well....." Amy stammered. "You...you..." She let out a sound of exasperation "killjoy!"

Liz gasped as if she's just been slapped. "Well, I never!" she said with a huff."

Wilson, standing there through all of this, could no longer restrain himself. He started to laugh out loud at the two. "Oh, my god." he said. "You two are the most odd couple of women I've ever had the privilege of knowing."

From her bed Amy asked Liz "Was that a compliment? He's your boyfriend. You know him better than I do."

Liz eyed James for a second and said "Yeah, I think so." She stepped back into the room. James followed. Amy looked ten times better than she had an hour earlier.

"You look like you feel a bit better." Wilson said.

Amy nodded. "I have Elizabeth to thank for that...and Teach."

Wilson nodded. "You certainly seem to be good at what you do." he said to Liz.

"Was there a doubt?" Liz asked. She raised up on her toes and kissed him on the mouth.

"Oh, puke!" Amy said from her bed. "If you're gonna do that, go in the hall." Liz gave her sister the finger. Amy scoffed. "I'm sick and maybe dying and you're giving me the finger. Ingrate."

Liz stopped kissing Wilson. She turned her head to Amy and said "invalid."

Amy glared. "smart ass."

"Dumb ass."

"Alright, alright. Ladies, please. Can we not do this again?" Wilson ran interference between the sisters. "I swear. You find out you're sisters and you start acting worse than ever. You realize the two fo you are making House look mature?"

"James, that hurt." Liz said playfully.

"Then stop being such a child."

"I am a child."

"No, you aren't." he argued.

Amy, again, from her bed snickered and called Wilson a "cradle robber." Liz started to laugh. All poor James Wilson could do was hang his head and admit defeat.

"I'm leaving with what little dignity I have left." he said with a short laugh. He kissed Liz once more and said "I'll see you later, OK."

"Ok." Liz agreed. "Dinner?"

"Sounds good. Where?" he asked.

"Not now. It'll only upset Amy because she's gotta choke down hospital food all night." Amy frowned. "I'll come to your office later."
